Couch Cot Cover Assembly for Functional Stacked-Cot Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-use furniture, such as chairs and sleeping cots, when stacked for storage, do not serve a useful purpose and occupy space without providing any functionality.
Innovation Solution
A couch cot cover assembly that includes a top cover assembly connected to a bottom cover assembly, with foam corner supports and a cushion assembly that conforms to the irregular surface of stacked cots, allowing the structure to be used as a seating assembly by providing structural support and padding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If stacked cots are used for storage, then space utilization is improved, but functionality is lost
Solution Approach 1:
The cover assembly transforms the stacked cots from a single-function storage object into a multi-functional unit that serves both as storage (maintaining compact stacked configuration) and as a functional seating surface. The cushion assembly and cover structure enable the stacked cots to provide seating functionality while remaining in their space-saving stacked position.
Solution Approach 2:
The cover assembly acts as an intermediary element that bridges the gap between the non-functional stacked cots and a functional seating surface. By placing the cushion assembly and cover over the stacked cots, the intermediary structure provides the necessary comfort and functionality while the underlying cots maintain their storage configuration.
2Adaptability or versatility
If a cover assembly is added to stacked cots, then seating functionality is provided, but device complexity increases
Solution Approach 1:
The cover assembly is divided into distinct segments including the cushion assembly, side panels, and fastening mechanisms. This segmentation allows for easier manufacturing, assembly, and maintenance while providing the necessary seating functionality. The modular structure reduces overall complexity by breaking down the cover assembly into manageable components.
Solution Approach 2:
The cover assembly utilizes flexible fabric materials and thin cushion layers rather than rigid structural elements. This approach reduces device complexity by using soft, form-fitting materials that naturally conform to the stacked cot shape, eliminating the need for complex rigid framing or support structures.
3Strength
If foam corner supports are added, then structural support is improved, but manufacturing complexity increases
Solution Approach 1:
The foam corner supports are integrated directly into the cushion assembly during manufacturing, combining multiple functions (corner protection, structural support, and cushioning) into a single manufactured component. This merging reduces the number of separate parts that need to be manufactured and assembled, thereby simplifying the overall manufacturing process while maintaining structural integrity.

AI summary
A cover assembly internally supported by a removable irregular object provides a seating apparatus. A top cover and a bottom cover are separated allowing access to the object within. A cushion assembly conforms to the irregular upper surface of the object forming a generally uniform top surface for the cover assembly. Foam structural supports in the corners of the cover assembly provide additional structural support and padding. A back support provides support for a person sitting on the cover assembly.
