Transport aid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional transport aids are difficult to disassemble, assemble, and adjust in width, making them cumbersome to carry and transport, and they cannot accommodate individuals of varying heights, widths, or disabilities, requiring caregivers to manually move and lift users, which increases mental and physical burden.
Innovation Solution
A transport aid composed of disassemblable members including left and right support members, a chair seat, and horizontal assembly frames, with retractable cable belts or ropes, allowing for quick assembly, adjustment in sitting height, width, and headrest position, enabling easy transportation of individuals with disabilities to desired locations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If conventional transport aids are designed to be folded for receiving, then they can be compacted, but the folded transport aid still takes up a lot of space making it difficult to carry, stow and transport
Solution Approach 1:
The transport aid is divided into multiple detachable members including a left support member, a right support member, a chair seat, and two horizontal assembly frames. This segmentation allows each component to be independently handled and stored, significantly reducing the space required for storage and transportation while maintaining ease of assembly and disassembly.
2Adaptability or versatility
If conventional transport aids have fixed dimensions, then they have simple structure, but they cannot be applicable to tall, short, fat or thin person with disability
Solution Approach 1:
The transport aid incorporates adjustable features that allow dynamic modification of dimensions including sitting height, width, and headrest position and angle. These adjustments enable the device to adapt to various body types and disabilities without requiring complex reconfiguration, achieving versatility through straightforward mechanical adjustments.
3Extent of automation
If conventional transport aids require manual moving and lifting by caregivers, then they have simple operation, but they increase mental and physical burden on caregivers
Solution Approach 1:
The transport aid incorporates a retractable mechanism with cable belts or ropes that enables the chair seat to swing automatically from an original location to a desired location. This self-service mechanism reduces the need for manual intervention by caregivers, allowing the system to perform transport functions autonomously while minimizing the physical burden on users.
4Productivity
If transport aid components are permanently assembled, then they have high structural stability, but they cannot be quickly disassembled and assembled
Solution Approach 1:
The transport aid is designed with detachable connections between its segmented components (left support member, right support member, chair seat, and horizontal assembly frames). These connections enable quick assembly and disassembly operations while maintaining structural stability when assembled, achieving both portability and structural integrity.

AI summary
The present disclosure illustrates a transport aid which can be quickly assembled, disassembled, and adjusted in width, and includes two support members, a chair seat and two horizontal assembly frames, wherein the horizontal assembly frames are disposed on left and right sides of the chair seat, respectively, and each includes a first quick connector assembled to a corresponding second quick connector of the chair seat, and ends of the two horizontal assembly frames are pivotally connected to corresponding support members, respectively, and other ends of the two horizontal assembly frames are assembled to each other through a quick packing connector for forming a horizontal bottom support member. As a result, the transport aid can be quickly disassembled into members for easy carry; furthermore, these members can be quickly assembled to a transport aid as a wheelchair, so that any person with disability can sit thereon and easily and comfortably be transported.
