Engineering Contradiction Analysis
1Volume of moving object
If the spacing between the lighting means device and the lamp housing is reduced to achieve a compact structure, then the lamp size is reduced, but electrical insulation breakdown occurs between the lighting means device and housing
Solution Approach 1:
An insulation component made of electrically insulating material is introduced as an intermediary between the lighting means device and the lamp housing. This mediator enables close spacing while preventing electrical breakdown by providing the necessary insulation barrier.
Solution Approach 2:
The insulation component is strategically positioned only where electrical insulation is needed - between the lighting means device and the housing - rather than insulating the entire housing. This localized approach maintains compactness while providing necessary insulation.
2Reliability
If the lighting means device is screened in an electrically insulating manner from the lamp housing, then electrical insulation is ensured, but the lamp structure becomes more complex
Solution Approach 1:
The insulation component is implemented as a thin-walled structure made of electrically insulating material that provides the necessary insulation while occupying minimal space. This thin-film approach ensures insulation without adding significant structural complexity.
3Reliability
If heat is efficiently removed from the housing to enable operation at high voltages, then safety is improved, but additional cooling components increase device complexity
Solution Approach 1:
The lamp housing itself serves as a heat sink, utilizing its own thermal mass and surface area to dissipate heat from the lighting means device. This self-service approach enables efficient heat removal without requiring additional active cooling components.
