Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If bonding device is used to bond display panel and optical member, then manufacturing capability is improved, but alignment precision deteriorates due to alignment errors

Engineering Contradiction:

Improvemanufacturing capabilityVSAvoidalignment precision

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

Offset data representing the relative arrangement position between three-dimensional lenses and sub-pixels is stored in advance in a storage device. This preliminary action allows the main controller to access and apply the offset data before image display, compensating for alignment errors without requiring complex real-time adjustment mechanisms during manufacturing.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system changes the parameter of image data by applying offset compensation. The main controller corrects image data based on the offset data, effectively transforming the alignment error parameter into a correctable variable that can be adjusted through data processing rather than physical repositioning.

Inventive Principle:

Principle #35Parameter changes

2Manufacturing precision

If offset data compensation is applied, then alignment precision is improved, but device complexity increases due to additional storage and control components

Engineering Contradiction:

Improvealignment precisionVSAvoiddevice complexity

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

Offset data serves as an intermediary element between the physical alignment error and the image display output. Rather than directly adjusting the physical components, the system introduces offset data as a mediator that bridges the gap between misaligned components and correct image presentation, simplifying the control mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces a potentially complex mechanical adjustment system with a data-based compensation approach. Instead of using mechanical mechanisms to physically realign the optical member and display panel, the system substitutes this with electronic offset data storage and image data correction, reducing mechanical complexity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If user correction value is incorporated, then adaptability is improved, but ease of operation deteriorates due to additional user input requirements

Engineering Contradiction:

ImproveadaptabilityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system incorporates user correction values as a feedback mechanism. Users can provide correction inputs based on their viewing experience, and the main controller uses these feedback values to adjust the offset data. This creates a closed-loop system that adapts to individual user preferences and viewing conditions.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The offset data system is made dynamic by allowing user correction values to modify the stored offset data. Rather than being a static compensation value, the offset data can be adjusted in real-time based on user feedback, enabling the system to adapt to changing viewing conditions and user preferences.

Inventive Principle:

Principle #15Dynamics
