Solution Overview

Problem

Projector light source modules require excessive assembly time and device volume due to multiple independent heat sink structures for different temperature-operating light source components, increasing complexity and size.

Innovation Solution

A light source module configuration where the first light source component (red) and the second light source component (green or green-blue) share a heat sink structure, reducing the number of heat sink members and assembly time, with the third light source component (blue) having its own heat sink, and the fourth light source component (auxiliary blue) converting blue light to enhance green light, thereby optimizing heat dissipation and module compactness.

Core Design Contradiction:
TemperatureVSVolume of stationary object

Solution Approach 1:

The patent merges multiple independent heat sink structures into a single integrated heat sink structure that serves multiple light source components simultaneously. This integration maintains effective heat dissipation for each component while reducing the overall device volume and eliminating redundant structures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated heat sink structure is designed to perform multiple heat dissipation functions for different light source components (red, green, and blue light sources) within a single structure, making the heat sink system universal and multi-functional rather than requiring separate dedicated heat sinks for each component.

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

Solution Approach 1:

By combining multiple heat sink structures into one integrated unit, the patent reduces the number of assembly operations required. Instead of installing and positioning multiple separate heat sinks, the integrated structure can be installed as a single component, significantly reducing assembly time while maintaining heat dissipation effectiveness.

Inventive Principle:
Principle #5Merging (Combining)

3Temperature

If plural independent heat sink structures are used for different light source components, then heat dissipation for each component is optimized, but device complexity is significantly increased

Engineering Contradiction:

Solution Approach 1:

The patent integrates multiple heat dissipation functions into a unified heat sink structure, reducing structural complexity. Instead of managing multiple independent heat sink components with separate mounting and positioning requirements, the integrated structure simplifies the overall device architecture while still providing optimized heat dissipation for each light source component.

Inventive Principle:
Principle #5Merging (Combining)
