Folding Chair With Detachable Cooler and Ergonomic Webbing Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Folding chairs often lack comfort and durability due to their rigid materials and inadequate back support, which become uncomfortable over time and fail to contour to the human body, especially in high-use settings.
Innovation Solution
A folding chair design featuring a detachable, reconfigurable, and interchangeable insulated container, carrying straps, and cup holder, constructed with aircraft-grade aluminum and fabric webbing for comfort, along with adjustable and ergonomic armrests, allowing multiple carrying configurations and improved storage options.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If rigid materials (metal, plastic, wood) are used for seats and backrests, then structural strength and durability are improved, but comfort deteriorates over time as surfaces degrade and become weathered
Solution Approach 1:
The patent applies flexible fabric webbing material to replace rigid seat and backrest surfaces. The fabric is stretched over the frame structure, providing both comfort through soft contact and durability through tension-based support. This flexible covering resolves the contradiction by eliminating the weathering issues of rigid materials while maintaining structural integrity through the webbing tension system.
2Ease of manufacture
If one-dimensional flat seats and backrests are used, then manufacturing simplicity is improved, but comfort deteriorates as they fail to contour to the human body
Solution Approach 1:
The patent implements local quality by varying the density and arrangement of fabric webbing in different regions of the seat and backrest. The webbing is configured to provide enhanced support in areas requiring it (such as lumbar support regions and seat contours) while maintaining simplicity in the overall manufacturing process. This allows the flat structure to provide differentiated comfort zones without complex shaping.
3Adaptability or versatility
If backrest portions are minimized for folding operation and storage, then portability and storage space are improved, but back support adequacy deteriorates
Solution Approach 1:
The patent employs a dynamic backrest design that can transition between compact folded positions for portability and extended positions for adequate back support. The fabric webbing backrest is configured to provide full back support when the chair is in use, while the entire assembly can be folded flat for storage and transport. The dynamic nature of the folding mechanism allows the backrest to adapt between these two states.
4Ease of operation
If thick, high-quality padding is used to improve comfort, then comfort is improved, but weight and bulk increase
Solution Approach 1:
The patent uses thin fabric webbing material that provides comfort through its flexibility and ability to conform to the body, rather than through thick padding. The webbing material is lightweight yet provides adequate cushioning and support through its tensile properties and close fit to the body contours, eliminating the need for heavy foam or cushioning layers.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The chair provides enhanced comfort and durability with its ergonomic design and versatile carrying options, maintaining comfort and functionality even in heavy use, while the insulated container keeps items cold for extended periods.
Implementation Method 1
The container can be insulated and can be easily and conveniently attached and detached from the folding chair

AI summary
Portable chairs including a detachable container. The container can be insulated for keeping beverages and food cold for an extended period. The folding chair preferably is designed and constructed for the demands of the outdoors. Various detachable, reconfigurable, and/or interchangeable features including the container, carrying straps, and cup holder. The container can be easily and conveniently attached and detached from the folding chair. The container can have exterior pockets which are welded and sealed to protect items contained within. The straps can have multiple different attachment points which allow multiple different carrying styles and reconfigurations including a backpack type carrying configuration, over-the-shoulder briefcase type carrying configuration, and across the body satchel type configuration, for example. The cupholder is interchangeable from each side of the folding chair and can be designed to accommodate various types of beverage containers including cups having a handle, a can, and a canteen, for example.
