Detachable Backpack and Folding Chair Coupling for Independent Use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing combined folding chair and backpack arrangements are deficient in being non-detachable, limiting access to storage and requiring users to carry the entire chair to the destination, with inconveniently positioned storage pouches and fixed carrying straps.
Innovation Solution
A folding chair and backpack arrangement with a coupling system that allows for easy detachment and reattachment, featuring adjustable harness straps that can route through or around the chair frame for ergonomic carrying, enabling hands-free mobility and separate use of the backpack and chair.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the backpack is permanently fixed to the folding chair, then the user can carry the chair on their back and store goods in the storage portion, but the user cannot easily access goods in storage when the chair is in the seating position and must bring the entire chair to the location of goods
Solution Approach 1:
The backpack is designed as a detachable component from the folding chair through a coupling system with interconnected elements. The coupling assembly includes a first coupling element on the chair and a second coupling element on the backpack that can connect and disconnect, allowing the backpack to be separated from the chair for independent access while maintaining the ability to carry them together when needed.
2Adaptability or versatility
If the backpack and chair are made as a single detachable unit, then the user can use the backpack traditionally or carry both together, but the coupling system becomes more complex
Solution Approach 1:
The coupling system is designed with universal applicability where the coupling elements can connect the backpack to the chair for combined carrying, yet allow separation for independent use. The same coupling mechanism serves multiple functions: securing the backpack during transport, enabling traditional backpack wear, and providing storage attachment when needed, without requiring different mechanisms for each use case.
Solution Approach 2:
A coupling assembly acts as an intermediary between the backpack and folding chair, providing a standardized interface that simplifies the connection and disconnection process. The coupling elements serve as mediators that enable versatile usage options while maintaining structural integrity, reducing the complexity burden by providing a single standardized interface rather than multiple specialized connections.
3Ease of operation
If the carrying straps are fixed to the chair frame and fabric, then the chair can be carried on the back, but the user cannot position the chair at the most ergonomic location
Solution Approach 1:
The carrying straps are designed with dynamic adjustability, allowing the user to route and position the straps at different locations on the chair frame and fabric. The straps can be configured to accommodate various chair positions and user preferences, transforming the fixed strap system into an adjustable one that adapts to ergonomic requirements while maintaining carrying functionality.

AI summary
A combination chair and backpack arrangement. The arrangement includes the folding chair, wherein the folding chair includes a foldable frame, a back support panel, a seat panel, at least one backpack coupler, and at least one harness coupler; the backpack, wherein the backpack comprises at least one pouch, at least one coupler releasably couple able to the backpack coupler, and at least one harness coupler; and a harness arrangement, wherein the harness arrangement includes a first end coupled to the backpack and a harness coupler selectively coupleable to the at least one harness coupler associated with the backpack and the at least one harness coupler associated with the folding chair; wherein when harness coupler of the harness arrangement is coupled to the at least one harness coupler associated with the backpack, the backpack is carriable independently of the folding chair, and the backpack and the harness arrangement forms a closed loop; and when the harness coupler of the harness arrangement is coupled to the at least one harness coupler associated with the folding chair, the folding chair and the backpack are carriable together.
