Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple single-line laser devices are used to improve obstacle detection coverage, then detection capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent integrates multiple laser light sources (at least two) onto a single substrate, combining what would traditionally be separate laser devices into one unified component. This merging approach maintains the enhanced obstacle detection capability while reducing device complexity by eliminating the need for multiple separate laser assemblies and their associated mounting structures
Solution Approach 2:
The substrate serves as a universal platform that simultaneously supports multiple laser light sources and integrates the collimating component. This multi-functional design allows a single component to perform the functions of multiple separate devices, thereby improving obstacle detection coverage without proportionally increasing device complexity
2Measurement precision
If multiple single-line laser devices are used to eliminate blind zones, then obstacle detection accuracy is improved, but cost increases
Solution Approach 1:
By merging multiple laser light sources onto a single substrate with a shared collimating component, the patent reduces the total number of parts that need to be manufactured and assembled. This approach maintains the obstacle detection accuracy needed to eliminate blind zones while lowering manufacturing costs through economies of scale and reduced assembly complexity
Solution Approach 2:
The patent emits lasers at different inclination angles (including vertical and inclined directions) from the same substrate, utilizing angular dimensionality to expand detection coverage. This allows the system to detect obstacles in multiple spatial dimensions simultaneously, eliminating blind zones without requiring multiple physically separated devices
3Volume of moving object
If a single substrate with multiple laser light sources is used, then device size is reduced, but manufacturing precision requirements increase
Solution Approach 1:
The substrate is divided into distinct regions, with each region designated for a specific laser light source and its corresponding shaping component. This segmentation approach organizes the compact layout into manageable zones, reducing the manufacturing precision challenges that would arise from attempting to integrate all components in a random or unorganized manner
Solution Approach 2:
Each region on the substrate is optimized for its specific function, with laser light sources and shaping components positioned and configured according to their local requirements. This local quality approach allows each component to be manufactured and positioned with precision tailored to its specific needs, rather than requiring uniform high precision across the entire device
4Adaptability or versatility
If laser light sources emit at different inclination angles, then obstacle detection coverage is improved, but optical system complexity increases
Solution Approach 1:
Each shaping component is specifically designed and positioned to control the laser beam at its local region, with different inclination angles achieved through localized optical configurations rather than a complex global optical system. This allows multiple detection directions to be achieved while keeping the overall optical system relatively simple
