Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a reed switch is used to control device operation, then the device can be controlled magnetically, but additional current is consumed reducing battery lifespan
Solution Approach 1:
The patent extracts the control function from the power consumption function. The reed switch is removed and replaced with a control circuit that uses voltage thresholds to determine operation without requiring continuous current flow. Only the essential control function is retained while the power consumption aspect is eliminated.
Solution Approach 2:
The patent replaces the mechanical/magnetic reed switch system with an electronic control circuit. Instead of using magnetic fields to physically close contacts, the invention uses voltage detection and comparison circuits to control operation, substituting a magnetic-mechanical system with an electronic system that consumes less power.
2Use of energy by moving object
If an external power source is used to control operation, then internal power consumption is minimized, but the device requires voltage threshold detection capability
Solution Approach 1:
The patent changes the control parameter from magnetic field strength (in the reed switch system) to voltage level (in the new system). By detecting voltage thresholds rather than magnetic fields, the control circuit can determine operation state with simpler electronics that consume less internal power, accepting the trade-off of added circuit complexity.
3Productivity
If voltage thresholds are used to decide operation presence, then operation control becomes efficient, but the device requires multiple terminal connections
Solution Approach 1:
The patent makes the terminals multi-functional. The same terminals that receive power from the external power source also serve as the detection points for voltage threshold comparison. This universal use of terminals allows efficient operation control without requiring separate dedicated detection terminals, reducing overall connection complexity.
