Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a transilluminated LC display or controllable transmitted light projector is incorporated into the light section sensor, then user-friendliness and operational efficiency are enhanced through intuitive visualization of measurement settings directly on the object, but device complexity increases due to additional projection components
Solution Approach 1:
The patent merges the display function with the existing light section sensor by incorporating a transilluminated LC display or controllable transmitted light projector into the sensor housing. This integration allows measurement settings and parameters to be projected directly onto the measurement area, eliminating the need for separate external display devices and reducing overall system complexity despite adding projection components.
Solution Approach 2:
The LC display or projector acts as an intermediary element that translates internal sensor settings into visible projections on the measurement area. This mediator provides intuitive visual feedback to users, making complex measurement parameters easily understandable without requiring additional external hardware or complex adjustment procedures.
2Productivity
If visible information is projected directly onto the measurement area using the third structured light beam, then operational efficiency is improved through dynamic visualization of measurement boundaries, but energy consumption increases due to additional light sources
Solution Approach 1:
The third structured light beam serves multiple functions: it defines measurement boundaries and simultaneously projects visible information about measurement settings and parameters onto the measurement area. This multi-functionality eliminates the need for separate illumination sources, reducing overall energy consumption while maintaining operational efficiency.
Solution Approach 2:
The system dynamically adjusts the parameters of the third structured light beam, including its intensity and modulation characteristics, to optimize the balance between providing sufficient visible information for user guidance and minimizing energy consumption. The projection is activated only when needed during measurement operations.
