Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If constant time pulses are used for diffusion activation, then the device can operate under worst-case conditions, but energy wastage increases significantly

Engineering Contradiction:
Improveoperation reliability under worst-case conditionsVSAvoidenergy wastage
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent applies dynamics by transitioning from fixed, constant time pulses to variable pulse widths that adapt to actual operating conditions. The control unit dynamically adjusts the diffusion activation time based on real-time voltage detection, ensuring reliable operation across different battery charge levels while minimizing energy consumption when conditions are optimal.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent implements feedback by using the voltage detection unit to continuously monitor battery charge level and feed this information back to the control unit. This feedback loop enables the system to adjust pulse width in real-time, optimizing the balance between operational reliability and energy efficiency based on actual battery status rather than predetermined fixed intervals.

Inventive Principle:
Principle #23Feedback

2Reliability

If longer pulse durations are used to ensure diffusion under low battery voltage, then reliability improves, but battery service life decreases

Engineering Contradiction:
Improvediffusion reliability under low voltageVSAvoidbattery service life
Core Design Contradiction:
ReliabilityVSDuration of action of moving object

Solution Approach 1:

The system dynamically adjusts pulse duration based on detected voltage levels. When voltage is high, shorter pulses are used; when voltage drops to worst-case levels, the control unit automatically extends the pulse width to ensure adequate diffusion, thereby maintaining reliability throughout the battery service life without unnecessarily extending pulses during high-voltage periods.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent changes the temporal parameter (pulse width) of the diffusion activation based on the electrical parameter (voltage level). By detecting voltage and adjusting pulse duration accordingly, the system optimizes the trade-off between ensuring sufficient diffusion under low-voltage conditions and minimizing total energy consumption to extend battery service life.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If fixed pulse widths are applied, then device complexity is reduced, but dispensing consistency deteriorates

Engineering Contradiction:
Improvecontrol system simplicityVSAvoiddispensing consistency
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

The voltage detection unit provides real-time feedback on battery charge level to the control unit, enabling dynamic adjustment of pulse width. This feedback mechanism ensures consistent volatile substance dispensing across varying battery conditions without requiring complex algorithms, maintaining relatively simple device architecture while achieving improved dispensing consistency.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent replaces complex mechanical adjustment mechanisms with an electrical detection and control system. By using voltage detection and electronic pulse width modulation, the system achieves precise control over diffusion activation timing without requiring physical adjustment components, thereby maintaining simplicity while improving dispensing consistency.
