Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual adjustment of sensor settings is performed, then the sensor can be configured for presence detection, but the installation procedure becomes cumbersome and difficult
Solution Approach 1:
The sensor performs automatic self-configuration by detecting static elements in the environment and autonomously determining optimal detection parameters, eliminating the need for manual adjustment and simplifying installation procedures
Solution Approach 2:
The sensor conducts preliminary detection of the installation environment during setup, automatically identifying static elements and pre-configuring detection parameters before actual use, thereby streamlining the installation process
2Productivity
If manual adjustment of sensor settings is performed, then the sensor can be configured, but the configuration process becomes time-consuming and inefficient
Solution Approach 1:
The sensor automatically configures itself by detecting the environment and setting optimal parameters without human intervention, dramatically reducing configuration time and improving installation efficiency
Solution Approach 2:
The patent replaces manual mechanical adjustment of sensor parameters with automated electronic detection and configuration systems, eliminating time-consuming manual operations
3Adaptability or versatility
If the sensor detection range is increased to cover more area, then more targets can be detected, but false detections from static elements increase
Solution Approach 1:
The sensor applies different detection strategies to different spatial regions, using refined detection criteria in areas with static elements while maintaining broader detection coverage in open spaces, thereby improving overall accuracy
Solution Approach 2:
The sensor performs preliminary mapping of static elements in the environment and uses this information to adjust detection parameters and exclude static regions from active detection, preventing false detections while maintaining coverage
