Solution Overview

Problem

Existing lighting apparatuses face inefficiencies in both electrical connection and heat dissipation due to the need for radial forces on electrical contacts, which complicate the structure and can lead to instability.

Innovation Solution

The use of a base made of high-dissipative material, such as aluminum, with removable first connectors featuring insulating elements and rotation locking mechanisms, allows for efficient heat transfer and stable electrical connections without radial pressures, accommodating various light source configurations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If radial forces are applied to electrical contacts to maintain thermal contact, then heat dissipation is improved, but electrical connection stability deteriorates

Engineering Contradiction:
Improveheat dissipationVSAvoidelectrical connection stability
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The base is divided into functionally distinct zones: a heat dissipation zone with high thermal conductivity material for thermal contact, and an electrical connection zone with insulating material for stable electrical contacts. This segmentation allows each zone to optimize its specific function without interfering with the other.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the base have different material properties tailored to their specific functions. The heat dissipation region uses materials with high thermal conductivity, while the electrical connection region uses materials with high electrical insulation properties. This local differentiation resolves the contradiction by providing appropriate material characteristics in each location.

Solution Approach 1:

The base integrates multiple functions into a single component: it provides structural support, thermal dissipation, and electrical insulation. By combining these functions in one element rather than using separate components, the design reduces overall structural complexity while maintaining effective thermal contact.

Inventive Principle:
