Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high machining accuracy is used for recesses and protruded blocks, then firm and stable connection is achieved, but manufacturing cost and assembly difficulty increase
Solution Approach 1:
The patent introduces a fixing section with a dot structure as an intermediary element between the recess and the protruded block. This dot structure acts as a mediator that compensates for dimensional tolerances and machining variations, enabling stable connection without requiring high machining accuracy. The dot structure fills gaps and provides a reliable engagement interface that is tolerant to manufacturing variations.
Solution Approach 2:
The patent changes the geometric parameters of the connection interface by introducing a dot structure with specific dimensions and positioning. This parameter change allows the connection to accommodate a range of machining tolerances while maintaining firm engagement. The dot structure's size and position are optimized to provide stable connection across varying manufacturing conditions.
2Ease of manufacture
If machining accuracy is reduced to facilitate easy assembling, then manufacturing cost decreases, but gaps appear between components resulting in loose connection
Solution Approach 1:
The dot structure serves as a compensatory intermediary that bridges gaps between components when machining accuracy is reduced. It absorbs dimensional variations and maintains reliable connection even with lower precision machining, thus enabling easy assembly without sacrificing connection stability.
Solution Approach 2:
The dot structure provides beforehand cushioning by pre-compensating for potential gaps and dimensional variations. It is designed to accommodate expected machining tolerances, ensuring that even with reduced machining accuracy, the connection remains firm and stable without requiring post-assembly adjustments.

AI summary
An assembly of torque module for hinge device includes a torque module having two swing arm assemblies that are synchronously pivotally turnable relative to each other and extended transversely outward in two opposite directions to form a fitting section each; two swing supports symmetrically provided with two receiving sections for receiving the fitting sections therein through engagement of receiving grooves with fitting rails; and two elastic packing elements disposed in the receiving sections and respectively including a rib section downward pressed against a bottom of the receiving section and two lateral supporting sections upward pressed against a bottom of the fitting section. The elastic packing elements compensate any gap between the receiving grooves and the fitting rails to enable lower accuracy of machining the receiving sections and the fitting sections to reduce manufacturing cost while achieves firm and stable connection of the fitting sections with the receiving sections.
