Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If separate camera and display systems are used to capture and reproduce light fields, then functional capability is provided, but device complexity and bulk increase

Engineering Contradiction:
Improvesystem integrationVSAvoidlight field recreation accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent combines the camera sensor array and display array into a single integrated system mounted on opposite sides of the same circuit board. Each sensor pixel unit is directly mapped to corresponding display pixel units, merging the capture and reproduction functions into one unified device. This integration reduces overall system complexity while maintaining light field recreation accuracy through direct pixel correspondence.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated system performs multiple functions simultaneously - capturing light fields through the sensor array and reproducing them through the display array within the same device structure. The circuit board serves as a common substrate for both functions, enabling the system to act as both camera and display without requiring separate dedicated systems.

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

2Device complexity

If traditional image transformation methods are used to map sensor pixels to display pixels, then light field reproduction is achieved, but processing complexity and power requirements increase

Engineering Contradiction:
Improveimage transformation complexityVSAvoidpower requirements
Core Design Contradiction:
Device complexityVSUse of energy by moving object

Solution Approach 1:

The patent implements a direct one-to-one mapping where each sensor pixel unit is copied directly to corresponding display pixel units without requiring complex image transformation algorithms. This direct copying approach maintains the light field information while significantly reducing processing complexity and power consumption compared to traditional transformation methods.

Inventive Principle:
Principle #26Copying

3Measurement precision

If high-resolution light field capture is implemented, then accurate light field recreation is achieved, but device size and weight increase

Engineering Contradiction:

Solution Approach 1:

The patent uses a thin circuit board as the substrate to mount both the sensor array and display array, enabling high-resolution light field capture without significant increase in device thickness or weight. The flexible circuit board structure allows for compact integration of high-density pixel arrays while maintaining a lightweight form factor suitable for wearable applications.

Inventive Principle:

4Manufacturing precision

If more sensor pixels and display pixels are integrated, then light field resolution improves, but manufacturing complexity increases

Engineering Contradiction:
Improvepixel alignment precisionVSAvoidassembly complexity
Core Design Contradiction:

Solution Approach 1:

The patent divides the system into discrete sensor pixel units and corresponding display pixel units, each independently addressable and manufacturable. This segmentation allows for modular assembly where pixel units can be manufactured separately and then precisely aligned on the circuit board, reducing overall manufacturing complexity while enabling high-resolution configurations.

Inventive Principle:
Principle #1Segmentation
