The Wheelchairs A Journey of Innovation, & Independence

The wheelchair is more than just a mobility aid; it’s a symbol of independence, empowerment, and resilience for millions of people around the world. From its early inception to the advanced designs we see today, the wheelchair has undergone significant transformations, reflecting the evolving needs of users and the technological advancements of our times. This blog post delves into the history, innovation, and impact of wheelchairs, highlighting their crucial role in enhancing mobility and quality of life for individuals with disabilities.

The Origins of the Wheelchair

The concept of a wheelchair can be traced back thousands of years. The earliest known reference to a wheelchair-like device comes from ancient China, around the 6th century BC, where carts were used to transport people who could not walk. Similar devices were also used in ancient Greece and Egypt. However, these early wheelchairs were rudimentary and lacked the sophistication and functionality of modern designs.

The first recorded wheelchair that resembles what we recognize today was created in 1595 for King Philip II of Spain. This chair had small wheels at the front and larger ones at the back, allowing the user to be pushed by an attendant. Over the centuries, various improvements were made, but it wasn’t until the 18th century that wheelchairs began to be developed with the user’s independence in mind.

The Evolution of Wheelchair Design

The 19th and 20th centuries saw significant advancements in wheelchair design, driven by the need for more functional and comfortable mobility solutions. In 1869, the first patent for a wheelchair was filed in the United States. This design included large rear wheels and smaller front wheels, similar to modern manual wheelchairs. However, it was still relatively cumbersome and required considerable effort to propel.

The advent of lighter materials and improved engineering techniques in the early 20th century led to more user-friendly designs. The folding wheelchair, invented by Harry Jennings in 1932, was a game-changer. Jennings, who built the wheelchair for his paraplegic friend Herbert Everest, created a design that was lightweight, portable, and could be easily stored. This innovation laid the foundation for modern manual wheelchairs and marked a significant step toward greater independence for wheelchair users.

The Rise of Power Wheelchairs

While manual wheelchairs offered increased mobility, they still required physical strength and stamina to operate, which could be challenging for some users. The invention of the power wheelchair in the mid-20th century revolutionized mobility for many individuals. These wheelchairs are equipped with an electric motor, allowing users to navigate without the need for physical exertion.

The first power wheelchairs were developed in the 1950s, primarily for veterans returning from World War II with disabilities. These early models were bulky and expensive, limiting their accessibility. However, as technology advanced, power wheelchairs became more compact, efficient, and affordable. Today, they are available in a wide range of designs, with features like adjustable seating, customizable controls, and even smart technology integration.

Power wheelchairs have had a profound impact on the lives of users, offering greater independence and the ability to participate in daily activities with less assistance. For many, power wheelchairs are not just a mobility aid but a tool that enhances their overall quality of life.

Wheelchairs have empowered users to pursue education, employment, and social activities, contributing to a more inclusive and equitable society.

Accessibility and Inclusion: The widespread availability of wheelchairs has driven improvements in accessibility, leading to the development of ramps, curb cuts, accessible public transportation, and inclusive building designs. These changes have not only benefited wheelchair users but have also made public spaces more accessible to all, including parents with strollers and elderly individuals with mobility challenges.

Empowerment and Independence: For many wheelchair users, having access to a reliable and comfortable wheelchair is the key to independence. It allows them to move freely, make their own decisions, and participate fully in society. The sense of empowerment that comes with this independence is invaluable, contributing to better mental and physical health.

Cultural Representation and Awareness: The visibility of wheelchair users in media, sports, and public life has helped to challenge stereotypes and promote a more accurate and positive portrayal of people with disabilities. Events like the Paralympic Games and the increasing representation of wheelchair users in film and television have played a significant role in raising awareness and fostering greater understanding and acceptance.

Challenges and the Road Ahead

Despite the advancements in wheelchair technology and the progress made in accessibility, challenges remain. Many wheelchair users still face barriers, including high costs, limited access to suitable models, and societal stigma. Addressing these challenges requires continued innovation, advocacy, and a commitment to creating a more inclusive world.

One of the key challenges is the affordability of high-quality wheelchairs. While there are many options available, the most advanced models can be prohibitively expensive, limiting access for those with limited financial resources. Insurance coverage for wheelchairs varies widely, and in some regions, it can be difficult for users to obtain the devices they need.

Another challenge is the need for continued improvements in public infrastructure and transportation. While progress has been made in making public spaces more accessible, there is still work to be done to ensure that all environments are wheelchair-friendly.

Looking to the future, the development of even more advanced wheelchair technology, combined with a greater focus on inclusive design and accessibility, holds the promise of further enhancing the lives of wheelchair users. As society continues to evolve, so too will the wheelchair, adapting to the changing needs and aspirations of those who rely on it for mobility and independence.

3d Printing In Fashion Garment Industry: What To Look Forward

3D printing has started making its way into the fashion apparel industry. A number of designers are making use of the additive manufacturing technology to produce one-off complex designs; 3D printing services dedicated to fashion and design are emerging in the market. Fashion schools are adapting their programs, incorporating laser-cutting and 3D printing. Annual hi-tech fashion weeks are popping up around the globe


Such technology refers to the layer by layer. Creation of physical objects based on digital 3D files. Which described as having the power to disrupt and transform the manufacturing system as we know it. 3D printing transforms the design and development process by expanding spheres of possibilities, enhancing design quality and limiting development costs. It also incurs great consequences for manufacturing as it reduces transaction costs, resolves the scale-scope problem and fosters zero-waste production.

Technology

In recent years, the fashion industry has shown growing interest in 3D printing technologies and its affiliated 3D designing software. Traditionally the business and engineering communities have formed the foundation for research on the issue of 3D printing. And have provided the theoretical and empirical framework through which to analyze the adoption and impacts of 3D printing on the industrial sector.

The first 3D printer was introduced in 1986 by Chuck Hall. 3D printers manufacturers have been large R & D based organizations (De Jong et al, 2012) which were able to afford high prices and required premium products. However, with the patents for these technologies beginning to expire a number of firms, most of which were start-ups began entering the market, with a concentration on the lower end of the market. 

Transformative Effects of 3D printing:

3D printing also brings about many advantages in terms of manufacturing and supply chain management. It promotes customization to new design alternatives that can be created without the need for investments in setup, tooling or machine changeovers. As such, the marginal cost of reproduction is close to zero thus resolving the scale-scope dilemma imposed by traditional manufacturing technologies. Products are producing and sold efficiently in small batches (Michalik et al, 2015). As a result, 3D printing also limits concerns relative to stock. Inventories become obsolete when it becomes possible to produce according to make-to-order processes (Weller and al, 2015). Finally, 3D printing enables localized production. With 3D technologies, design and manufacturing can happen anywhere thus reducing transaction costs.


Innovation in the Creative Industries:

In order to assess the possible impact of 3D printing in terms of fashion. It is crucial to turn to the existing literature on the role of innovation in the creative industrie. as well as a past example of adoptions of digital innovations in this particular sector.

The difficulty to replicate the study, the problem of generalization and the risk of lack of transparency. There’s been general uneasiness for the application reliability and validity in qualitative research. The quality of the study will be guaranteed according to the alternative indicators of quality

Brief discussion of auto marker & making process

Brief discussion of auto marker & making process

Let’s get back to the initial time of cutting department of garments industries there is no facility like auto marker. All the time in bulk cutting they used marker, however; how did they make it? In that case; can you say that in a single sentence? Well let me tell you, they make it manually placing one pattern by by one. Marker is most important element to complete the bulk cutting.

Now question is what is marker in detail ?


Marker is sheet of paper. where every parts of garments are plotted as per layer or cutting plan. Always the marker man makes marker by breakdown a ratio from PO quantity. As per company working policy; this ration also can be provided by cutting planer. Marker maker input the ratio into marker making software to make desire marker for production.

This is the package of garments parts, which let us to enhance the cutting production with limited period of time.

How did they make manual marker?


Question Is little weird, isn’t it? How did they ? Because the manual marker making isn’t used in large production. This is very long process and it’s efficiency isn’t good as in computerized methods.


The maker man makes marker by placing one pattern by one. If maker Missed something he/she need to erase drawn marker and do that again. This is very complicated process & unable to change anything after finish the marker. It’s required much more time and manpower than computerized method.

What is Computerized method?



As I mention earlier, it’s easiest way to place the Patten one by one and check how much efficiency we are achieving n. On the other hand, if we change any placement and see much eefficiency increased or decreased. This is helps a lot the marker man to achieve desire efficiency goal.

Auto marker.


Technology improving rapidly and it’s adding new features everyday to progress CAD and CAM technology. Auto marker is one of them. It’s doesn’t take long time to make any marker. Within two minutes it can be possible to make any marker. which is at least 10 minutes work for a marker man. Almost every top ranking recognizes software company are providing such auto marker facilities with its main software by adding some extra charges.

How it’s work?


As simple as like convert a video files from .avi to .mkv . Just open the software, input the marker, set your desire time, setting and go for process. Done!

Point should be noted. “that the file type doesn’t change at all”. File type remain same. to reduce Fabric wastage all the pieces must placed perfectly


You can also send new created and unplaced marker to nesting directly from your working folder. Using “send to option” as like we send some file to flash drive from computer.
So simple!
