Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a touch screen is used for control, then ease of operation is improved, but reliability deteriorates due to accidental touches

Engineering Contradiction:
Improveease of operationVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

A lock switch is introduced as an intermediary component between the user and the touch screen. When activated, it blocks input signals from reaching the control circuit, thereby preventing accidental touches while maintaining the touch screen's ease of use when intentionally operated.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The lock switch provides preliminary protection by preemptively blocking accidental input signals before they can trigger unintended operations. This anti-action mechanism is activated in advance to prevent potential errors rather than correcting them after occurrence.

Inventive Principle:
Principle #9Preliminary anti-action

2Reliability

If control functions are added to prevent accidental touches, then reliability is improved, but device complexity increases

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The locking function is extracted as a separate, independent switch component rather than being integrated into the touch screen firmware or control circuitry. This modular approach adds reliability without significantly complicating the overall device architecture.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The lock switch operates independently with simple on/off functionality, managing its own state without requiring complex control logic or additional processing resources from the main control circuit, thereby minimizing the increase in device complexity.

Inventive Principle:
Principle #25Self-service
