Solution Overview
Problem
Conventional packaging structures rely heavily on adhesives, making them difficult to recycle and contributing to low recycling rates, as they require additional delamination processes and incur extra costs.
Innovation Solution
A glue-free supporting structure and displaying frame design featuring a foldable bottom plate, side plates, flip segments, and through holes, allowing for the formation of an accommodating space without adhesive fixation, enabling the structure to be reused and recycled efficiently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If adhesives are used for bonding and fixing during the manufacturing process, then structural integrity and stability are improved, but recyclability and ease of recycling deteriorate
Solution Approach 1:
The supporting structure is divided into multiple separable components including a bottom plate, side plates, and flip segments connected by score lines. This segmentation allows the structure to be assembled and disassembled without adhesives, maintaining structural integrity during use while enabling easy recycling by simply separating the components.
Solution Approach 2:
The adhesive component is completely removed from the structure. Instead of using adhesives for bonding, the patent employs mechanical connection methods such as flip segments that can be inserted through holes and folded to secure the bottom plate to side plates, eliminating the need for chemical bonding agents and facilitating recycling.
2Stability of the object's composition
If adhesives are used for bonding and fixing, then structural stability is improved, but manufacturing complexity and costs for recycling deteriorate
Solution Approach 1:
The structure is segmented into detachable parts connected by score lines and mechanical features like flip segments and through holes. This segmentation simplifies the recycling process by eliminating the need for complex delamination procedures required to remove adhesives, while still providing structural stability during the product's intended use.
Solution Approach 2:
By extracting and removing the adhesive component entirely, the patent eliminates the complexity of delamination processes. The structural stability is maintained through alternative mechanical connection methods that are inherently easier to reverse and separate, reducing both manufacturing complexity and recycling process complexity.
3Ease of manufacture
If conventional packaging materials are used, then ease of manufacture is improved, but environmental friendliness and recyclability deteriorate
Solution Approach 1:
The supporting structure uses segmentation to create a modular design with a bottom plate, side plates, and flip segments that can be manufactured separately and assembled without adhesives. This approach maintains manufacturing simplicity while improving environmental friendliness through easier recycling and reduced chemical usage.
Solution Approach 2:
The patent extracts and eliminates adhesive materials from the packaging structure, replacing them with mechanical connection methods. This removal of harmful adhesive substances improves environmental friendliness while the modular segmented design ensures that manufacturing remains simple and efficient.

AI summary
A supporting structure includes a bottom plate, a foldable area, a plurality of side plates, at least one flip segment, and at least one through hole. The side plates are disposed on edges of the bottom plate. Any two of the side plates that are adjacent are connected to each other, and the side plates form an accommodating space. A part of the at least one flip segment can be separated from at least one of the bottom plate and the side plates along a segmenting line. The at least one through hole and the at least one flip segment are disposed on at least one of the bottom plate and the side plates. When the bottom plate is folded along the foldable area, the partially separated flip segment is inserted into the through hole to fix the folded bottom plate and the side plates in position.
