Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional fastening apparatus is used, then the structure is simple, but it cannot connect components of different thicknesses
Solution Approach 1:
The fastening apparatus employs a rotary element that can rotate relative to the base element, transforming a static structure into a dynamic one. This rotation enables the abutting means to engage with components of varying thicknesses, providing adaptability while maintaining a relatively simple overall structure through controlled movement rather than multiple complex adjustable components
Solution Approach 2:
The fastening apparatus is divided into distinct functional segments: a base element with bayonet-like fastening means and a rotary element with abutting means. This segmentation allows each part to perform its specific function independently, enabling the system to accommodate different thicknesses through the rotation of the rotary element while keeping the base element structure simple
2Adaptability or versatility
If a fastening apparatus with rotational and axial movement is used, then it can connect components of varying thicknesses, but the operation becomes more complex
Solution Approach 1:
The fastening apparatus combines rotational movement and axial displacement into a single integrated operation. The threaded axial displacement device links the rotary element's rotation to its axial movement, so that one continuous motion performs both functions simultaneously, simplifying the operation despite the multi-dimensional movement required
Solution Approach 2:
The threaded axial displacement device acts as an intermediary mechanism that translates rotational motion into axial displacement. This mediator allows the user to perform a simple rotational action while the threaded mechanism automatically produces the necessary axial movement to engage components of different thicknesses, reducing operational complexity
3Reliability
If bayonet-like fastening means are used, then the connection is secure, but the device structure becomes more complex
Solution Approach 1:
The bayonet-like fastening means on the base element serves multiple functions: it provides secure retention on contour elements, enables rotational engagement, and works in conjunction with the rotary element's axial movement. This multi-functionality achieves reliable connection security while avoiding the need for separate dedicated mechanisms for each function, thereby limiting the increase in structural complexity
