Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a reed switch is used to control device operation, then operational control is achieved, but additional current is consumed reducing battery lifespan

Engineering Contradiction:

Improveoperational controlVSAvoidbattery lifespan

Core Design Contradiction:

Ease of operationVSDuration of action of moving object

Solution Approach 1:

The patent replaces the mechanical reed switch system with a voltage-based control system using passive electronic devices. Instead of using magnetic fields to actuate reed switches, the invention applies voltage from an external power source to control circuit nodes, eliminating the need for magnetic actuation and reducing internal power consumption while maintaining operational control capability.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The invention extracts the control function from the internal power system by introducing an external power source. The control voltage is supplied externally rather than being generated internally, separating the control function from the power consumption function and allowing the internal battery to be preserved for essential operations only.

Inventive Principle:

Principle #2Taking out (Extraction)

2Ease of operation

If additional current is consumed for reed switch operation, then operational control is maintained, but internal power consumption increases

Engineering Contradiction:

Improveoperational controlVSAvoidinternal power consumption

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent introduces an external power source as an intermediary to provide control voltage. This external power source acts as a mediator between the control signal and the device operation, supplying the necessary voltage without drawing current from the internal battery, thus reducing internal power consumption while maintaining full operational control.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention substitutes the reed switch's magnetic actuation mechanism with a voltage-based control mechanism using passive electronic devices. This substitution eliminates the need for current-consuming magnetic field generation and maintains control functionality through voltage application to control nodes.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
