Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If LED lighting is used for energy-efficient illumination, then energy consumption is reduced and lifespan is extended, but heat generation increases causing reliability issues

Engineering Contradiction:
Improveenergy consumptionVSAvoidreliability
Core Design Contradiction:
Use of energy by moving objectVSReliability

Solution Approach 1:

The patent extracts the heat dissipation function from the integrated lighting structure by introducing separate heat dissipation fins and air flow channels. The heat dissipation fins are positioned to conduct heat away from the LED modules, while air flow channels enable convective cooling, effectively separating the illumination function from the thermal management function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces air as an intermediary cooling medium that flows through dedicated channels between the heat dissipation fins. This air flow acts as a heat transfer medium, carrying thermal energy away from the LED modules without direct contact, thereby protecting the LEDs from excessive heat while maintaining efficient heat dissipation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Temperature

If heat dissipation structures are added to LED lighting, then thermal management is improved, but device complexity increases

Engineering Contradiction:
Improveheat dissipationVSAvoiddevice complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The patent merges the heat dissipation fins directly with the driver box structure, integrating the thermal management component into the existing housing rather than adding it as a separate assembly. The air flow channels are formed as integral features of the driver box, combining structural support and thermal management functions into a single unified component.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The driver box is designed to serve multiple functions: it provides electrical power to the LED modules, houses the control circuitry, and simultaneously acts as a heat dissipation structure through its integrated fins and air flow channels. This multi-functionality reduces the need for additional dedicated heat dissipation components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A lighting apparatus includes a light head, a driver box, multiple separating columns and a light source module. The light head has an Edison cap and a head body. The head body has a rotatable connector. The driver box has a first side and a second side for containing a driver circuit. The first side of the driver box has a fixing unit corresponding to the rotatable connector of the head body to selectively attach or detach the light head from the driver box by rotating the rotatable connector with respect to the fixing unit. The light source plate has a light source plate mounted with LED modules. The light source plate is fixed to the driver box with the multiple separating columns. The separating columns form an air gap between the driver box and the light source for heat dissipation.
