Innovation Solution

A leakproof structure for the lamp holder of the infrared lamp tube is designed with a concave elongated housing, a waterproof plug, and an automatic control system for coolant flow, ensuring contact heat dissipation and preventing coolant leakage by using an O-ring washer and internal nut for sealing, and an automatic control system that adjusts coolant flow rate based on temperature for optimal heat dissipation.

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 service life is reduced

Engineering Contradiction:

Improveservice life of halogen lampVSAvoidheat dissipation effect

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

A waterproof plug made of heat-conductive material serves as an intermediary component that enables thermal contact between the halogen lamp and cooling system while maintaining waterproof sealing. The plug fills the space between the lamp base and housing, providing both thermal conduction path and water tightness, thus resolving the contradiction between heat dissipation effectiveness and leakage prevention.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Loss of energy

If contact heat dissipation is implemented by allowing coolant to contact the halogen lamp, then heat dissipation effectiveness is improved, but the lamp holder becomes prone to water leakage

Engineering Contradiction:

Improveheat dissipation effectivenessVSAvoidwaterproof performance of lamp holder

Core Design Contradiction:

Loss of energyVSReliability

Solution Approach 1:

The waterproof plug acts as a mediator that enables thermal contact while preventing water leakage. It provides a controlled interface between the coolant circulation system and the halogen lamp mounting area, allowing heat transfer through its heat-conductive material while its sealing structure prevents coolant from penetrating into the lamp holder.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The waterproof plug utilizes a flexible sealing structure that can deform to accommodate the lamp base while maintaining water tightness. This flexible sealing interface allows for thermal contact without compromising the waterproof integrity of the lamp holder assembly.

Inventive Principle:

Principle #30Flexible shells and thin films

3Reliability

If a waterproof sealing structure is added to the lamp holder, then water leakage is prevented, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The waterproof plug combines multiple functions into a single component: it provides waterproof sealing, thermal conduction, and mechanical support for the halogen lamp. By merging these functions into one integrated part rather than using separate components, the design achieves reliable waterproofing without significantly increasing device complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The waterproof plug serves multiple purposes simultaneously: it seals the interface between the lamp holder and housing, conducts heat from the lamp to the cooling system, and provides mechanical mounting support. This multi-functional design reduces the need for additional specialized components, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A leakproof structure of the lamp holder, combined with an installation hole, which can ensure that the coolant in the accommodation space does not leak out; moreover, the lower part of the halogen bulb is covered by the waterproof plug in a tight state, so as to achieve a complete leakproof structure.
