Solution Overview

Problem

The challenge in projector devices is to improve heat dissipation in the optical machine module, which generates high heat during operation, while maintaining a compact size.

Innovation Solution

The optical machine module incorporates an internal radiator thermally coupled to a radiator cover, which is strategically positioned next to the light source within the module, enhancing heat transfer and dissipation.

If the projector device size is reduced, then the compactness is improved, but the heat dissipation capability deteriorates

Engineering Contradiction:

Improveprojector device sizeVSAvoidheat dissipation capability

Core Design Contradiction:

Volume of moving objectVSTemperature

Solution Approach 1:

The internal radiator is nested within the optical machine housing, positioned inside the inner space formed by the radiator cover and optical machine housing. This allows the heat dissipation component to be integrated within the limited device volume, enabling effective heat dissipation without increasing the overall projector size.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The radiator cover serves as an intermediary thermal conduction path between the light source and the internal radiator. The light source is disposed on the cover inner surface, thermally coupling to the radiator cover, which in turn is thermally coupled to the internal radiator, creating an efficient heat transfer chain within the compact structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

If an internal radiator is added to improve heat dissipation, then the heat dissipation effect is improved, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The radiator cover serves multiple functions: it forms part of the housing structure defining the inner space, provides a mounting surface for the light source, acts as a thermal conduction path, and supports the internal radiator. This multi-functionality reduces the need for separate dedicated heat dissipation structures, thereby limiting the increase in device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The heat dissipation function is merged with the existing housing structure. The internal radiator is integrated into the space between the radiator cover and optical machine housing, combining the heat dissipation component with the structural enclosure rather than adding it as a separate external component.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

An optical machine module includes an optical machine housing, a radiator cover, a light source, and an internal radiator. The radiator cover covers the optical machine housing to jointly form an inner space, and the radiator cover includes a cover inner surface facing the inner space. The light source is disposed on the cover inner surface. The internal radiator is located beside the cover inner surface and close to the light source, and the internal radiator is thermally coupled to the radiator cover.
