Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple projection devices are used to project images on different surfaces, then multiple directional projections are achieved, but device complexity and power consumption increase

Engineering Contradiction:

Improvemultiple directional projection capabilityVSAvoidnumber of devices and power sources

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple projection systems into a single integrated device with multiple lenses arranged in a housing. Each lens projects images in different directions, eliminating the need for separate projection devices while maintaining multi-directional projection capability. This merging reduces device complexity, power consumption, and mounting requirements.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The single projection device is designed to perform multiple functions by projecting images simultaneously in different directions through multiple lenses. The device can project onto various surfaces (walls, ceilings, floors) and display different content (images, video, art) through each lens, making it a universal solution for multi-directional projection needs.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple projection devices are deployed, then multiple images can be displayed on different surfaces, but power consumption increases

Engineering Contradiction:

Improvemulti-surface projection capabilityVSAvoidpower consumption

Core Design Contradiction:

Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

By merging multiple projection systems into a single device with shared power supply and control architecture, the patent reduces total power consumption. The integrated design allows efficient power distribution to multiple lenses and light sources, eliminating redundant power sources and reducing overall energy requirements while maintaining multi-surface projection capability.

Inventive Principle:
