Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connection is used for coupling objects, then the coupling strength and stability are improved, but the ease of separation and assembly speed deteriorate
Solution Approach 1:
The coupling mechanism is divided into separate components: a coupling body with coupling teeth and a separate fastening component with elastic elements. This segmentation allows the coupling and fastening functions to be independent, enabling quick release by simply disengaging the fastening component without affecting the coupling teeth engagement.
Solution Approach 2:
The patent introduces elastic elements (springs) that provide dynamic fastening force. The elastic elements can automatically adjust to maintain coupling pressure and enable quick release when force is applied, transforming the static screw connection into a dynamic system that responds to operational needs for both secure coupling and easy separation.
2Stability of the object's composition
If screw connection is used for coupling objects, then the stability of the coupling is improved, but the assembly time and productivity deteriorate
Solution Approach 1:
The coupling teeth are pre-configured in the coupling body, ready for engagement. The elastic fastening elements are pre-loaded to provide immediate coupling force. This preliminary preparation eliminates the need for step-by-step screw tightening, allowing rapid assembly by simply bringing the coupling parts together.
Solution Approach 2:
The elastic elements provide dynamic fastening that automatically maintains stable coupling pressure without requiring manual adjustment or tightening operations. This dynamic system achieves both assembly speed and coupling stability simultaneously.
3Ease of operation
If elastic element is used for fastening, then the ease of assembly and separation is improved, but the coupling strength may deteriorate
Solution Approach 1:
The patent merges two coupling mechanisms into one system: the elastic fastening elements provide ease of assembly and separation, while the interlocking coupling teeth provide mechanical strength and stability. The combination of these two mechanisms resolves the trade-off between ease of operation and coupling strength.
Solution Approach 2:
The coupling mechanism uses composite structural design combining elastic elements (for flexibility and ease of operation) with rigid coupling teeth (for strength and stability). This composite approach allows each component to contribute its optimal properties to the overall coupling system.

Function Achieved in This Case
The motion body facilitates quick and repeated coupling and separation of objects by using an elastic element to securely fasten and unfasten the coupling portion with the counterpart object.
Implementation Method 1
two ends of the elastic element respectively abut against the coupling portion and the second body to enable the motion body to be elastically assembled or elastically fastened with a counterpart object

AI summary
A motion body and a coupling method thereof are introduced. The motion body includes a first body and a coupling portion. The coupling portion is provided with a second body and an elastic element. The second body is disposed at the first body, and two ends of the elastic element respectively abut against the coupling portion and the second body to allow the coupling portion to enter a counterpart object and be located at a residing position or a pause position, enabling the motion body to be elastically assembled or elastically fastened with the counterpart object and to lift or fix an object by the first body. Thus, with coordination of the motion body, the counterpart object and the object, quick coupling of at least two objects can be completed to achieve effects of repeatedly quick coupling and separation.
