Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional milling depth setting methods are used, then additional tools and aids are required, but this increases device complexity and costs
Solution Approach 1:
The patent combines the depth indication function with the base plate structure by integrating a laser diode directly into the base plate. The laser diode projects a light spot that indicates the milling depth, merging the depth measurement function into the existing base plate rather than requiring separate external aids or tools.
Solution Approach 2:
The machine tool performs its own depth indication function through the integrated laser diode system. The laser diode automatically projects the depth indicator without requiring external measurement tools or additional aids, allowing the system to serve itself for depth measurement.
2Measurement precision
If additional depth setting aids are added to achieve precise milling depth, then measurement precision improves, but manufacturing cost increases
Solution Approach 1:
The patent merges the depth indication function with the base plate structure by integrating a laser diode directly into the base plate. This integration eliminates the need for separate external measurement aids, reducing the overall system cost while maintaining precise depth indication capability.
Solution Approach 2:
The patent uses a laser diode, which is a relatively inexpensive and compact component, to provide precise depth indication. The laser diode can be easily replaced if needed, providing a cost-effective solution compared to more complex or expensive measurement systems.
3Ease of operation
If a laser diode is integrated into the base plate for depth indication, then ease of operation improves, but device complexity increases
Solution Approach 1:
The laser diode integrated into the base plate automatically provides depth indication without requiring operator intervention or external tools. The system self-regulates the depth indication function, making operation simpler even though the base plate structure is more complex.
Solution Approach 2:
The patent replaces traditional mechanical depth measurement methods with an optical laser diode system. This substitution simplifies operation by providing visual feedback through a light spot, eliminating the need for mechanical gauges or manual measurement procedures.
