Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If traditional profiles and connection pieces are used to construct display racks, then the display frame can be assembled, but the structure becomes cumbersome and storage/transport becomes inconvenient
Solution Approach 1:
The display rack is divided into modular components: display frames, corner connection pieces, and intermediate connection pieces. Each component is independently designed and manufactured, then assembled on-site. This segmentation allows for simplified individual parts while maintaining overall functionality, resolving the contradiction between ease of manufacture and structure complexity.
Solution Approach 2:
The corner connection pieces and intermediate connection pieces are designed to nest within the frame structure, with rotating mechanisms that allow components to fold into each other. This nesting approach reduces the overall footprint and simplifies storage/transport while maintaining the complete structure during use, addressing both manufacturing simplicity and structural complexity.
2Reliability
If multiple connection parts are used for assembly, then the display frame can be constructed, but construction becomes time-consuming and laborious
Solution Approach 1:
Multiple connection functions are merged into single integrated components. The corner connection pieces combine locking, positioning, and structural support functions in one element. The intermediate connection pieces integrate folding and connecting capabilities. This merging reduces the number of separate parts and assembly steps while maintaining assembly reliability through multifunctional design.
Solution Approach 2:
The connection pieces are designed with self-aligning and self-locking features. The rotating mechanisms automatically position components correctly during assembly, and the structural design ensures proper engagement without requiring precise manual alignment. This self-service capability maintains assembly reliability while significantly improving construction speed and efficiency.
3Adaptability or versatility
If traditional folding mechanisms are used, then some folding capability is achieved, but the structure remains cumbersome and stability is reduced
Solution Approach 1:
The connection pieces incorporate rotating mechanisms that enable dynamic transformation between folded and unfolded states. The rotation joints provide controlled movement while maintaining structural integrity in both configurations. This dynamic design achieves adaptability for folding while preserving stability through engineered joint mechanics and structural geometry.
4Adaptability or versatility
If existing folding display racks are designed, then folding is possible, but manufacturing cost increases and construction becomes complicated
Solution Approach 1:
The corner connection pieces at different positions are designed with uniform structure and dimensions, allowing for standardized manufacturing processes. The intermediate connection pieces also follow consistent design patterns. This homogeneity enables batch production, reduces tooling costs, and simplifies quality control, thereby reducing manufacturing costs while maintaining the folding function.

Implementation Method 1
the lower rotation piece is connected to the lower corner body through the lower pin shaft and is rotatable around the lower pin shaft towards an inner side of the display frame
Implementation Method 2
with one end of the lower pin shaft as a reference point, the other end of the lower pin shaft inclines downwards and towards the inner side of the display frame
