Foldable Chessboard Box with Independent Supporting Feet
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Foldable chessboard assemblies suffer from unstable placement when used as a chessboard, leading to a non-flat surface, which affects the playing experience due to the higher end surface of the connecting portion causing the surfaces to not splice properly into a plane.
Innovation Solution
The design incorporates first and second supporting portions with positioning slots and feet that are flush and higher than the connecting portion, allowing the surfaces to fit flatly when opened, and locking mechanisms to maintain stability and prevent pieces from falling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the connecting portion end surface is made higher than the chessboard surfaces, then the folding and carrying convenience is improved, but the chessboard surface stability and flatness deteriorate
Solution Approach 1:
The chessboard is divided into multiple board sections that can be folded relative to each other. Each section has its own supporting feet that can independently contact the supporting surface, allowing the structure to maintain stability while accommodating the elevated connecting portion for convenient folding and carrying.
Solution Approach 2:
Supporting feet are introduced as intermediary elements between the chessboard sections and the supporting surface. These feet act as mediators that transmit the board's weight to the surface while compensating for the height difference created by the elevated connecting portion, ensuring stable and flat surface formation.
2Adaptability or versatility
If the connecting portion end surface is made higher than the chessboard surfaces, then the portability is improved, but the flatness of the chessboard surface deteriorates
Solution Approach 1:
The chessboard is segmented into multiple sections with independent supporting feet. This segmentation allows each section to maintain proper contact with the supporting surface despite the elevated connecting portion, preserving the overall flatness of the playing surface while enabling easy folding and carrying.
Solution Approach 2:
The height parameter of the supporting feet is specifically designed to compensate for the elevated connecting portion. By adjusting the foot height, the system maintains the chessboard surface at the correct elevation relative to the supporting surface, ensuring flatness while preserving portability.
3Stability of the object's composition
If supporting feet are added to maintain flatness, then the chessboard surface stability is improved, but the device complexity increases
Solution Approach 1:
The supporting feet are merged with the existing board sections as integral parts rather than separate additions. This merging approach maintains flatness and stability while minimizing the increase in device complexity, as the feet are incorporated into the board's overall structure rather than being added as separate components.
