Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fastening member is used to secure the device to the external device, then the reliability of attachment is improved, but the ease of operation for attachment and detachment deteriorates
Solution Approach 1:
The fastening member transitions from a static structure to a dynamic one that rotates between engaged and disengaged positions. The rotation mechanism allows the fastening member to move along its axis, enabling secure attachment when engaged and easy detachment when disengaged, thus resolving the contradiction between attachment security and operational ease
Solution Approach 2:
The fastening mechanism is divided into distinct functional segments: the fastening member itself, the receiving portion, and the rotation prevention member. This segmentation allows each component to perform its specific function independently, with the fastening member providing secure attachment and the rotation prevention member ensuring proper orientation, thereby maintaining both reliability and ease of operation
2Reliability
If a rotation prevention member is added to prevent unintended detachment, then the reliability of attachment is improved, but the device complexity increases
Solution Approach 1:
The rotation prevention member is integrated with the fastening member as a unified structure. The rotation prevention member extends from the fastening member and works in conjunction with it, eliminating the need for separate components and reducing overall structural complexity while maintaining attachment stability
Solution Approach 2:
The rotation prevention member automatically engages with the receiving portion when the fastening member is rotated into the engaged position. This self-acting mechanism prevents unintended detachment without requiring additional control systems or complex actuation mechanisms, thus improving reliability without significantly increasing device complexity
3Ease of operation
If the fastening member is designed to rotate for attachment, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The fastening member incorporates asymmetric features including an inclined surface and a non-circular cross-section for the rotation prevention member. The inclined surface guides the rotation operation, making it intuitive and easy to perform, while the asymmetric geometry of the rotation prevention member ensures it can only engage in one orientation. These asymmetric designs simplify the user operation while the features can be manufactured using standard precision machining techniques

Function Achieved in This Case
The solution ensures stable, easy attachment and detachment of the device to external devices, preventing unintended separation and enabling versatile positioning, thereby enhancing usability.
Implementation Method 1
The operation member may have an inclined surface at one end thereof that extends in a first direction. The first sliding member may include a second inclined surface facing the first inclined surface... The first sliding member may slide in a second direction by a force applied from the first inclined surface to the second inclined surface as the operation member moves in the first direction
Implementation Method 2
The connecting member may include a fourth inclined surface adjacent to the third inclined surface. The connecting member may move in a third direction opposite to the first direction as the first sliding member slides in the second direction
