Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional coupling methods are used to connect stand base and stand neck, then connection strength is improved, but assembly and disassembly complexity increases
Solution Approach 1:
The coupling hole and elastic block are integrated into the coupling portion structure, merging the fastening function and locking function into a single integrated component. This eliminates the need for separate coupling members while maintaining both connection strength and ease of assembly.
Solution Approach 2:
The elastic block automatically engages with the coupling hole through elastic deformation when the stand neck is inserted, and automatically locks without requiring external tools or additional coupling members. The structure serves itself by using the elastic property of the block to create automatic engagement and locking.
2Reliability
If secure locking mechanism is implemented, then reliability of connection is improved, but ease of operation deteriorates
Solution Approach 1:
The elastic block automatically engages with the coupling hole through elastic deformation when the stand neck is inserted, and automatically locks without requiring external tools or additional coupling members. The structure serves itself by using the elastic property of the block to create automatic engagement and locking.
Solution Approach 2:
The elastic block changes its physical state through elastic deformation, transitioning from a compressed state during insertion to an expanded state during locking. This parameter change enables the block to provide secure locking while maintaining ease of operation through simple insertion and removal motions.
3Ease of operation
If tool-free assembly is implemented, then ease of operation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The elastic block changes its physical state through elastic deformation, transitioning from a compressed state during insertion to an expanded state during locking. This parameter change enables the block to provide secure locking while maintaining ease of operation through simple insertion and removal motions.
Solution Approach 2:
The coupling mechanism is divided into distinct functional elements: the coupling hole, the elastic block, and the coupling portion. This segmentation allows each component to be manufactured with standard tolerances while achieving precise engagement through the elastic deformation of the block, reducing overall manufacturing precision requirements.

AI summary
A supporting device for supporting a display may include a stand base including a first coupling portion; and a stand neck including a second coupling portion being couplable with the first coupling portion, the stand neck being supported by the stand base and being connectable to a rear side of the display. The first coupling portion may include: a first coupling body formed in a hollow shape; and a coupling hole formed in the first coupling body. The second coupling portion may include: a second coupling body being insertable in the first coupling body; a spring accommodated inside the second coupling body; and an elastic block being movable relative to the second coupling body by the spring and corresponding to the coupling hole.
