Foldable camping seat
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camping chairs are not ergonomically correct for most users, leading to discomfort, especially for larger individuals, as they do not accommodate the natural angle of the lower back and buttocks, resulting in reduced comfort over time.
Innovation Solution
A foldable camping seat with flexible bracings on both sides and a seat back, featuring a tension-resistant connection and an elastic zone in the upper part of the seat back that adjusts to the user's size, allowing for a customizable angle and increased contact area for comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed angle seat back is used, then the structure is simple and compact, but it is not ergonomically correct for most users leading to discomfort
Solution Approach 1:
The patent applies the dynamics principle by introducing an elastic zone that allows the seat back to dynamically adjust its angle and shape according to the user's body contours. The elastic material enables the seat back to transition from a fixed structure to a flexible, adaptive structure that automatically conforms to different body types without requiring complex mechanical adjustment mechanisms.
Solution Approach 2:
The patent implements parameter changes by modifying the physical state of the seat back material from rigid to elastic. This allows the seat back to change its geometric parameters (angle, curvature, width) in response to user weight and body shape, providing ergonomic adaptability while maintaining a simple overall structure.
2Stability of the object's composition
If the seat back is made rigid to maintain shape, then structural stability is improved, but comfort is reduced for larger individuals as corners stick into the back
Solution Approach 1:
The patent applies flexible shells and thin films by using an elastic material for the seat back that can flex and conform to the user's body. This flexible approach eliminates rigid corners and edges that cause discomfort, while the elastic properties maintain sufficient structural stability to support the user's weight and preserve the essential seat back shape.
Solution Approach 2:
The elastic material inherently provides cushioning before contact with the user's body. The material's elasticity allows it to deform smoothly under pressure, distributing forces evenly and preventing pressure points from forming at corners or edges, thus providing beforehand cushioning that prevents discomfort.
3Adaptability or versatility
If the seat back width is fixed, then manufacturing is simplified, but it cannot accommodate various body types effectively
Solution Approach 1:
The patent uses parameter changes by allowing the seat back width to vary dynamically through the elastic material's properties. The material can stretch and expand to accommodate wider bodies or narrower bodies without requiring multiple fixed-width models, thus achieving body type adaptability while maintaining a single standardized manufacturing process.
4Volume of moving object
If the seat back angle is fixed, then the device is more compact for storage, but it causes the upper back to rest against the upper part of the seat back leading to gnawing discomfort
Solution Approach 1:
The patent applies dynamics by enabling the seat back angle to adjust dynamically based on user weight and body shape. The elastic material allows the seat back to tilt and angle itself appropriately for each user, providing ergonomic comfort while maintaining a compact folded state for storage, as the flexibility is only activated during use.
