Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional solid stands are used to ensure stability, then the holder is stable, but the manufacturing process becomes complex and the thickness increases
Solution Approach 1:
The patent uses a thin elastic sheet structure instead of solid thick material. The sheet is bent and rolled into a cylindrical shape to form the holder, achieving stability through the rolled configuration rather than material thickness. This resolves the contradiction by maintaining stability while using minimal material and simplifying manufacturing.
Solution Approach 2:
The holder transitions from a flat static sheet to a dynamic rolled structure. The elastic sheet is bent and rolled into a cylinder that can adapt to different tableware sizes, providing stability through the three-dimensional formed structure rather than inherent material thickness.
2Strength
If conventional solid stands are used, then the holder provides adequate support, but storage space is occupied and resources are wasted due to washing requirements
Solution Approach 1:
The patent employs a disposable paper or thin plastic sheet that can be discarded after use, eliminating the need for washing and extending the lifecycle management. This resolves the contradiction by providing adequate support during use while eliminating resource consumption associated with cleaning and maintenance.
Solution Approach 2:
The material parameters are changed from solid permanent materials to thin elastic disposable materials. The sheet structure provides sufficient mechanical support for temporary use, then is discarded, changing the lifecycle parameter from reusable-to-clean to single-use-to-discard, thereby reducing resource consumption.
3Stability of the object's composition
If conventional stands are made with certain thickness for stability, then the holder is stable, but the manufacturing process is complex and storage space is required
Solution Approach 1:
The flat sheet structure can be nested or folded into a compact form for storage, then expanded and rolled into a stable cylindrical holder during use. This resolves the contradiction by achieving a stable three-dimensional structure during use while occupying minimal storage space in the collapsed state.
Solution Approach 2:
The holder transitions from a two-dimensional flat sheet to a three-dimensional rolled structure during use, achieving stability through the third dimension. For storage, it returns to the two-dimensional flat state, minimizing volume. This dimensional transformation resolves the contradiction between stability and storage volume.

AI summary
The present invention relates to a simple holder which includes an elastic first sheet structure. The first sheet structure has a first side and a second side which are opposite to each other, a hole located between the first side and the second side, a first cutting slit formed by cutting from the edge of the first side inwards, and a second cutting slit formed by cutting from the edge of the second side inwards. The center of the hole is located between the first cutting slit and the second cutting slit. The first sheet structure can be bent to make the first cutting slit slotting into the second cutting slit for locking. The simple holder provided by the present invention is formed by sheets and is thus convenient to be manufactured, transported and stored.
