Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple sensors are monitored to detect motion status of cartridge components, then measurement precision and reliability are improved, but device complexity and data processing requirements increase
Solution Approach 1:
The system divides the monitoring function into multiple independent sensors positioned at different locations on the cartridge (e.g., proximal and distal ends). Each sensor independently monitors specific motion parameters, allowing the complex monitoring task to be segmented into manageable components that can be processed separately, thereby improving measurement precision without proportionally increasing overall system complexity.
Solution Approach 2:
A control circuit acts as an intermediary between the multiple sensors and the processing system. This intermediary consolidates sensor signals, performs initial data processing, and manages data transmission to the external system. By introducing this intermediary layer, the patent reduces the burden on the external processing system while maintaining high measurement precision through coordinated multi-sensor monitoring.
2Productivity
If sensor data collection and transmission is optimized, then productivity and efficiency are improved, but use of energy and data transmission requirements increase
Solution Approach 1:
The system implements periodic data transmission rather than continuous transmission. Sensors collect motion status data continuously, but data is transmitted to the external system at optimized intervals or triggered by specific events (e.g., when motion thresholds are exceeded). This periodic action maintains high productivity by ensuring timely data availability while significantly reducing energy consumption compared to continuous transmission.
Solution Approach 2:
The system dynamically adjusts transmission parameters such as sampling rate and data transmission frequency based on the current operational state and motion activity levels. When motion is minimal or stable, sampling rates are reduced to conserve energy. When significant motion or critical events occur, the system increases sampling and transmission frequency to maintain productivity. This adaptive parameter adjustment optimizes the balance between efficiency and energy consumption.
