Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex securing mechanism is used to attach the actuator to the housing, then the attachment is secure and reliable, but the device complexity increases and production costs rise
Solution Approach 1:
The strap is divided into distinct functional segments: a first region for axial fixation and a second region for rotational fixation. This segmentation allows each region to be optimized for its specific function while keeping the overall structure simple and easy to manufacture.
Solution Approach 2:
The strap acts as an intermediary component between the actuator and the housing, providing both axial and rotational fixation functions. This single intermediary element replaces what would otherwise require multiple separate securing mechanisms, thereby reducing overall device complexity while maintaining secure attachment.
2Adaptability or versatility
If the actuator is fixed in multiple positions, then the adaptability for different detection tasks is improved, but the securing mechanism becomes more complex
Solution Approach 1:
The strap performs multiple functions simultaneously: it provides axial fixation, rotational fixation, and enables positioning at multiple discrete rotation angles. This multi-functionality is achieved through a single simple component design, avoiding the need for separate mechanisms for each function and thereby maintaining low device complexity.
Solution Approach 2:
The strap allows the actuator to be positioned at various discrete rotation angles while maintaining secure fixation. The dynamic capability to accommodate multiple positions is achieved through the geometric design of the strap regions rather than through complex adjustable mechanisms, keeping the securing mechanism simple.
3Ease of manufacture
If a simple strap design is used to reduce production complexity, then manufacturing is easier and more economical, but the mechanical robustness and security of attachment may be compromised
Solution Approach 1:
The strap is segmented into specialized regions where the first region is optimized for axial fixation and the second region for rotational fixation. This segmentation allows each region to be designed for its specific mechanical demand, ensuring robust attachment while keeping the overall strap design simple and easy to manufacture.
Solution Approach 2:
Different regions of the strap have different structural qualities optimized for their specific functions. The first region has structural characteristics suited for axial fixation while the second region has characteristics suited for rotational fixation. This local optimization ensures mechanical robustness in each function without requiring the entire strap to be overly complex or heavy.
