Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If acceleration sensors and microphones are used to detect fitting work, then detection capability is improved, but detection accuracy deteriorates due to similar sounds and accelerations from various hand operations
Solution Approach 1:
The patent combines data from multiple sensors (acceleration sensors, microphones, and pressure sensors) to create a composite detection signal. By merging these different types of sensory information, the system can distinguish fitting operations from other hand operations more accurately, resolving the contradiction between detection capability and detection accuracy.
Solution Approach 2:
The patent introduces pressure information as an additional dimension of detection beyond the traditional acceleration and sound data. This extra dimensional information from pressure sensors provides new discriminative features that enable accurate identification of fitting operations even when acceleration and sound patterns are similar to other operations.
2Measurement precision
If multiple sensors are used to improve detection accuracy, then work content detection precision is improved, but device complexity increases
Solution Approach 1:
The patent integrates multiple sensor types (acceleration, sound, and pressure sensors) into a single multi-functional detection system. This universal approach allows one integrated system to perform multiple detection functions simultaneously, improving work content detection precision while managing device complexity through consolidation rather than separate systems.
Solution Approach 2:
The patent introduces a signal processing unit that acts as an intermediary between the multiple sensors and the detection algorithm. This intermediary component processes and integrates the raw data from different sensors, managing the complexity of multiple sensor inputs and transforming them into meaningful detection signals.
3Productivity
If acceleration information from hand operations is used, then work detection capability is improved, but false detection increases due to unexpected collisions and similar accelerations
Solution Approach 1:
The patent segments the detection process into multiple independent sensor inputs (acceleration, sound, and pressure) that are processed separately before being integrated. This segmentation allows the system to analyze each sensor's data independently, identifying patterns specific to fitting operations while filtering out false signals from unexpected collisions or similar accelerations from other operations.
Solution Approach 2:
The patent implements a feedback mechanism where the detection system continuously monitors multiple sensor inputs and adjusts its detection thresholds and algorithms based on the combined information. This feedback loop improves detection reliability by learning from patterns and reducing false detections while maintaining high work detection capability.
