Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If non-contact heat dissipation is used for halogen lamps, then the risk of water leakage is reduced, but the heat dissipation effect is insufficient and the working temperature remains too high

Engineering Contradiction:
Improvewater leakage preventionVSAvoidworking temperature of halogen lamp
Core Design Contradiction:
ReliabilityVSTemperature

Solution Approach 1:

The patent introduces a waterproof plug as an intermediary component that enables contact between the coolant and halogen lamp while preventing water leakage. The plug mediates between the requirement for effective heat dissipation (contact cooling) and the requirement for leakage prevention, allowing the coolant to cool the lamp directly while the waterproof plug blocks the leakage path.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the state of the sealing interface by introducing a waterproof plug that creates a new parameter state - a sealed contact interface. This allows the system to transition from non-contact heat dissipation (with leakage prevention) to contact heat dissipation (with controlled sealing), optimizing both heat transfer efficiency and leakage prevention.

Inventive Principle:
Principle #35Parameter changes

2Temperature

If contact heat dissipation is implemented by allowing coolant to contact the halogen lamp, then heat dissipation effectiveness improves, but the risk of water leakage increases

Engineering Contradiction:
Improveheat dissipation effectivenessVSAvoidwater leakage risk
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The waterproof plug serves as a mediator that enables the coolant to contact the halogen lamp for effective heat dissipation while simultaneously preventing water leakage. The plug creates a controlled interface where thermal contact is maintained but fluid leakage is blocked.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The waterproof plug acts as a flexible sealing element that conforms to the interface between the lamp holder and coolant channel, creating a reliable seal while allowing thermal contact. The plug's sealing properties enable contact heat dissipation without compromising the waterproof integrity of the system.

Inventive Principle:
Principle #30Flexible shells and thin films

3Power

If the halogen lamp operates at high temperature for extended periods, then the infrared heating function is maintained, but the service life and reliability of the lamp are greatly reduced

Engineering Contradiction:
Improveinfrared heating functionVSAvoidservice life of halogen lamp
Core Design Contradiction:
PowerVSDuration of action of stationary object

Solution Approach 1:

The patent implements continuous contact heat dissipation through the waterproof plug and coolant system, maintaining a continuous cooling action on the halogen lamp. This continuous heat removal prevents temperature accumulation that would otherwise reduce lamp lifespan, while the lamp continues to operate at full power for infrared heating.

Inventive Principle:
Principle #20Continuity of useful action

Solution Approach 2:

The patent changes the thermal parameter of the halogen lamp operating system by introducing active contact cooling. This parameter change allows the lamp to operate at full power continuously without the temperature buildup that previously limited service life, effectively decoupling power output from thermal degradation.

Inventive Principle:
Principle #35Parameter changes

AI summary

A leakproof structure of the lamp holder (13), combined with an installation hole (112), which can ensure that the coolant (W) in the accommodation space(111) does not leak out; moreover, the lower part of the halogen bulb(13) is covered by the waterproof plug (123) in a tight state, so as to achieve a complete leakproof structure. Therefore, according to the temperature of the coolant (W), the automatic control system calculate the optimal flow rate of the coolant (W) in a proportional mode that the higher the temperature, the faster the flow rate, so as to achieve the most effective mode of heat dissipation, then perform contact heat dissipation to the halogen bulb (13) to solve the problem of the non-contact heat dissipation of halogen bulb (13) of the prior art that cannot achieve the predetermined heat dissipation effect and resulting in the easy damage of halogen bulb (13); and further improves the product reliability and the service life.
