Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple touch screens are provided to enable various operations, then functionality and versatility are improved, but device complexity increases

Engineering Contradiction:

ImprovefunctionalityVSAvoiddevice complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The display device is divided into multiple independent touch screens, each capable of displaying different content and responding to touch inputs separately. This segmentation allows each screen to perform specialized functions while maintaining overall system versatility.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each touch screen is designed to support multiple operations including touch input, display output, and various interaction modes. The system provides universal functionality across all screens, allowing any screen to serve multiple purposes depending on the operational context.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If multiple touch screens are provided for various operations, then adaptability is improved, but ease of operation deteriorates

Engineering Contradiction:

ImproveadaptabilityVSAvoidease of operation

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

Multiple touch screens are integrated into a unified system with coordinated control. The screens work together as a combined interface, allowing users to perform complex operations by interacting with multiple screens simultaneously or sequentially, thereby maintaining ease of operation while enhancing adaptability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

A control system acts as an intermediary between the user and multiple touch screens, managing the complexity of coordinating operations across screens. This intermediary layer processes touch inputs and displays appropriate content, shielding users from the underlying system complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple touch screens are provided, then versatility is improved, but control complexity increases

Engineering Contradiction:

ImproveversatilityVSAvoidcontrol complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system dynamically adjusts the functionality and coordination of multiple touch screens based on operational context. The control mechanism adapts to different usage scenarios, automatically managing screen assignments and interactions to maintain versatility while minimizing control complexity.

Inventive Principle:

Principle #15Dynamics
