Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If multiple cameras at multiple angles are used for shooting, then the display image can be captured completely, but the cost increases significantly

Engineering Contradiction:

Improveimage capture completenessVSAvoidmanufacturing cost

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

A light collimation module is introduced as an intermediary component between the curved display panel and the single camera. This module collimates the light beams reflected from different regions of the curved panel, enabling a single camera to capture the entire display image without requiring multiple cameras at different angles, thus reducing cost while maintaining capture completeness

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical approach of using multiple cameras positioned at different angles with an optical approach using a light collimation module. This substitution eliminates the need for complex mechanical positioning and multiple camera systems, reducing manufacturing cost while achieving the same imaging goal

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of manufacture

If a single camera is used for multiple times shooting, then the cost is reduced, but the implementation complexity increases

Engineering Contradiction:

Improvemanufacturing costVSAvoidshooting scheme complexity

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

The light collimation module serves as an optical intermediary that enables a single camera to capture the entire curved display panel in one shot by collimating light from different regions. This eliminates the need for complex multi-shot procedures, reducing implementation complexity while maintaining cost efficiency

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The light collimation module performs preliminary optical processing by collimating light beams before they reach the camera sensor. This preliminary action prepares the optical paths from different regions of the curved panel, enabling complete image capture in a single shot without requiring complex post-processing or multiple shooting sequences

Inventive Principle:

Principle #10Preliminary action

3Measurement precision

If multiple cameras or complex shooting schemes are used, then complete image capture is achieved, but the process is not conducive to mass production

Engineering Contradiction:

Solution Approach 1:

The light collimation module enables complete image capture in a single shot, eliminating the need for multiple cameras or repeated shooting sequences. This single-shot capability significantly improves production throughput and makes the compensation process suitable for mass production environments

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces complex mechanical positioning systems and multi-camera arrangements with a stationary light collimation module and single camera setup. This substitution simplifies the manufacturing process, reduces setup time, and enables high-speed mass production while maintaining complete image capture capability

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)
