Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual programming is used to configure slave display units, then the system can be set up, but the configuration process becomes time-consuming and impractical

Engineering Contradiction:
Improveconfiguration processVSAvoidconfiguration time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The slave display units automatically identify themselves and determine their locations through sensing elements that detect contacts with neighboring units. The system performs self-configuration without requiring manual programming, where each slave unit autonomously senses its position and transmits this information to the master display unit for automatic arrangement configuration.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical programming operations with an automated sensing system. Sensing elements (such as sensors, detectors, or identification devices) automatically detect the physical arrangement of display units and convert this physical information into digital data for configuration, eliminating the need for manual input.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Loss of information

If manual programming is used to configure slave display units, then location information can be input, but the process becomes complex and requires specialized knowledge

Engineering Contradiction:
Improvelocation informationVSAvoidprogramming complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

Slave display units automatically determine their own location information through sensing elements that detect contacts with neighboring units. The system performs self-identification and self-configuration, where each slave unit autonomously senses its position and transmits this information without requiring external programming knowledge or complex setup procedures.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex manual programming operations with an automated sensing system. Sensing elements automatically detect the physical arrangement of display units and convert this physical information into digital data for configuration, eliminating the need for manual input and specialized programming knowledge.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Adaptability or versatility

If display units are rearranged, then the system can be reconfigured, but manual programming steps must be repeated

Engineering Contradiction:
Improverearrangement capabilityVSAvoidreconfiguration time
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

The system is designed to be dynamically reconfigurable through automatic sensing. When display units are rearranged, the sensing elements detect the new physical arrangement and the system automatically updates its configuration accordingly. This dynamic adaptation allows the system to handle rearrangements without requiring manual reprogramming.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The sensing elements provide continuous feedback about the physical arrangement of display units to the master display unit. When units are rearranged, the sensing elements detect the change and transmit new location information, enabling the system to automatically update its configuration based on real-time physical state feedback.

Inventive Principle:
Principle #23Feedback
