A portable body support device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable support devices for seated passengers on long trips, such as airplanes, are uncomfortable and often require bending or specialized stabilization plates, limiting their usability and causing fatigue due to restricted positions and potential neck strain.
Innovation Solution
A portable device with a telescopically adjustable elongated support member and pivotable headrest support, allowing secure positioning on any seating area without specialized plates, supporting the upper body in both forward and backward leaning positions without requiring neck bending, using lightweight materials and ergonomic design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a stabilization plate is placed in front of the seat or attached to the front edge, then the head support device can be stably positioned, but the device can only be used in a forward leaning position and requires special mounting plates
Solution Approach 1:
The device is divided into separate functional components: a base unit that interfaces with the seat, a telescopic support member that provides adjustable height, and a headrest assembly. This segmentation allows each component to be optimized independently and enables the device to adapt to different seating configurations without requiring specialized mounting plates.
Solution Approach 2:
The base unit is designed with a universal interface that can accommodate various seat types and configurations. The telescopic support member provides multi-position adjustment capability, allowing the device to function in both forward and backward leaning positions, eliminating the limitation of single-position stabilization plates.
2Device complexity
If the support device requires the person to bend their neck towards the head support, then the device can be simpler in structure, but the neck may be injured due to bending
Solution Approach 1:
The headrest assembly is mounted on the telescopic support member, allowing dynamic adjustment of the headrest position and angle. This dynamic configuration enables the headrest to be positioned naturally against the user's head without requiring neck bending, while keeping the overall device structure relatively simple through the use of basic mechanical components.
3Adaptability or versatility
If the elongated support member is made adjustable to body height, then the device adapts to individual users, but the device complexity increases with telescopic mechanisms
Solution Approach 1:
The telescopic support member allows continuous adjustment of the support height parameter to match different user body dimensions. This parameter adjustment capability provides excellent adaptability while using a well-established mechanical telescopic mechanism that balances functionality with reasonable complexity.
4Weight of moving object
If the device uses lightweight materials for portability, then the device can be carried as hand luggage, but the structural strength may be reduced
Solution Approach 1:
The device utilizes composite material construction, combining lightweight materials with strategically placed reinforcement elements. This approach maintains portability by keeping overall weight low while ensuring sufficient structural strength through the composite design that targets critical load-bearing areas.
