Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the power of the blowing is increased to increase the scope of ioniser, then the scope is improved, but the electrical consumption increases
Solution Approach 1:
The patent applies dynamics by using a pulsed airflow mechanism instead of continuous blowing. The blower operates in pulses, creating intermittent airflow that carries ions forward. This dynamic approach allows the ioniser to achieve extended scope during pulse periods while consuming less energy overall compared to continuous operation at the same average flow rate.
Solution Approach 2:
The patent implements periodic action through pulsed airflow generation. The blower cycles between on and off states, creating periodic bursts of air that transport ions. This periodic operation achieves the desired ion distribution over a larger area while reducing the average electrical consumption compared to continuous blowing at equivalent effectiveness.
2Area of stationary object
If the power of the blowing is increased to protect multiple individuals simultaneously, then the protection scope is improved, but the electrical consumption increases making it incompatible with extended use when travelling
Solution Approach 1:
The pulsed airflow mechanism enables the ioniser to achieve wide protection coverage during active pulse periods while maintaining low average power consumption. The dynamic on-off operation allows ions to be distributed over a large area during pulses, then disperse during off periods, providing multi-person protection without requiring continuous high-power operation.
Solution Approach 2:
By using periodic pulsed blowing, the device achieves extended protection scope across multiple individuals during the pulse cycles while keeping the average electrical consumption low enough for portable use during travel and outdoor activities without mains power availability.
3Reliability
If conventional ionisers are used to repel insects, then individual protection is achieved, but the scope is limited and cannot protect several individuals simultaneously
Solution Approach 1:
The pulsed airflow dynamically propels ions forward in bursts, creating an expanding ion cloud that covers a larger spatial volume. This dynamic ion distribution extends the protection zone from a single-person radius to a multi-person area, while maintaining the ion concentration needed for effective insect repulsion during the pulse periods.
Solution Approach 2:
The periodic pulsed operation creates repeated ion distribution cycles that progressively expand the protected volume. Each pulse reinforces the ion presence in the air, maintaining effective concentrations over a larger area that can protect multiple individuals simultaneously while keeping average power consumption low.
