Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single optical lens group is used in conventional projection apparatus, then the device structure is simple, but it cannot project realistic 3D stereoscopic images

Engineering Contradiction:

Improve3D stereoscopic image projection capabilityVSAvoidoptical lens group configuration

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple optical lens groups (first optical lens group for visible light, second optical lens group for invisible light) into a single integrated optical lens module. This merging approach enables the system to project both visible images and invisible light patterns (such as infrared patterns for human-machine interaction) simultaneously, achieving 3D stereoscopic image projection and interaction sensing without requiring separate devices, thus resolving the contradiction between enhanced adaptability and device complexity.

Inventive Principle:

Principle #5Merging (Combining)

2Adaptability or versatility

If additional devices are added for human-machine interaction, then interaction functionality is enhanced, but the device volume increases

Engineering Contradiction:

Improvehuman-machine interaction capabilityVSAvoiddevice volume

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The optical lens module is designed with multi-functionality to serve both projection and interaction sensing purposes. The first optical lens group projects visible light images while the second optical lens group projects invisible light patterns (e.g., infrared) that can be used for gesture recognition and human-machine interaction. By integrating these functions into a single compact module, the system achieves enhanced adaptability without increasing device volume, as the same physical space houses multiple functional components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Volume of moving object

If multiple optical lens groups are integrated in a compact module, then device miniaturization is achieved, but manufacturing complexity increases

Engineering Contradiction:

Improveprojection system sizeVSAvoidlens group integration difficulty

Core Design Contradiction:

Volume of moving objectVSEase of manufacture

Solution Approach 1:

The patent employs a nested structure where the second optical lens group (for invisible light) is positioned around or alongside the first optical lens group (for visible light) within a shared housing. This nesting arrangement allows multiple optical lens groups to be integrated in a compact configuration, achieving device miniaturization. The nested design also facilitates streamlined manufacturing by reducing the number of separate assemblies required, as the lens groups share common mounting structures and optical paths.

Inventive Principle:

Principle #7Nested doll (Nesting)
