Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a 3D space measurement device uses rotation and tilt driving units to move the measurement position, then measurement capability and versatility are improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The device is divided into modular functional units: a light transmission unit (laser emitter), a light reception unit (position-sensitive detector), a rotation driving unit, and a tilt driving unit. Each unit performs a specific function and can be independently manufactured and assembled, reducing overall system complexity while maintaining measurement versatility
Solution Approach 2:
The support plate serves multiple functions: it holds the light transmission and reception units, acts as a rotating platform, and functions as a tilting surface. This multi-functionality reduces the number of separate components needed, simplifying the device structure while enabling both rotation and tilt operations for comprehensive spatial measurement
2Adaptability or versatility
If a 3D space measurement device uses rotation and tilt driving units to move the measurement position, then measurement capability is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the device into standard modular units (laser emitter, position-sensitive detector, rotation mechanism, tilt mechanism), each component can be manufactured using conventional processes and assembled like building blocks, reducing overall manufacturing complexity and cost
Solution Approach 2:
The patent uses commercially available off-the-shelf components such as standard laser diodes, position-sensitive detectors, and motorized rotation/tilt mechanisms. These standardized components are mass-produced and readily available, significantly reducing manufacturing costs compared to custom-designed systems
3Ease of manufacture
If the scanner structure is simplified, then ease of manufacture and portability are improved, but measurement precision may be compromised
Solution Approach 1:
The patent replaces complex mechanical measurement mechanisms with an optical system. A laser beam transmits distance information, and a position-sensitive detector optically measures the reflected light position. This substitution eliminates the need for complex mechanical linkages and moving parts, simplifying the structure while maintaining high measurement precision through optical triangulation
Solution Approach 2:
The light reception unit uses a position-sensitive detector that automatically determines the position of reflected light on the support plate without requiring additional mechanical measurement devices. The detector self-calibrates and provides direct digital position information, eliminating the need for complex mechanical measurement mechanisms and reducing structural complexity
