Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the housing is made fixed and non-adjustable, then the device structure is simpler and more durable, but the lighting direction cannot be adjusted to different positions
Solution Approach 1:
The housing is designed to be rotatable relative to the base portion, allowing the lighting direction to be dynamically adjusted. The retaining screw mechanism enables the housing to be secured at different angular positions while maintaining structural integrity, thus providing adaptability without excessive complexity.
Solution Approach 2:
The device is divided into separable components: a base portion and a housing that can rotate independently. The retaining screw acts as a coupling mechanism that allows selective connection and disconnection, enabling adjustment of the housing position while keeping the overall structure manageable and not overly complex.
2Adaptability or versatility
If the retaining screw structure is added to enable rotation, then the lighting direction can be adjusted, but the device structure becomes more complex
Solution Approach 1:
The retaining screw serves multiple functions: it secures the housing to the base portion, allows for angular adjustment, and can be easily removed for repositioning. This multi-functionality reduces the need for additional complex mechanisms, thereby limiting the increase in device complexity while achieving the desired adaptability.
3Adaptability or versatility
If fixed beam spread optics are used, then the device structure is simpler, but the lighting pattern cannot be adjusted for different applications
Solution Approach 1:
The beam spread optics are designed to be interchangeable, allowing the user to dynamically change the lighting pattern according to different application requirements. The optics assembly can be removed and replaced without complex tools or procedures, providing versatility while keeping the optics assembly relatively simple.
