Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the sensing threshold is increased to reduce false touches in noisy environments, then the reliability is improved, but the sensitivity is decreased

Engineering Contradiction:
Improvetouch accuracyVSAvoidsensitivity
Core Design Contradiction:
ReliabilityVSMeasurement precision

Solution Approach 1:

The sensing threshold is dynamically adjusted based on environmental conditions detected by the environment sensing device. The control device automatically modifies the threshold value according to the detected environment type (noisy or clean), allowing the system to maintain high reliability in noisy environments while preserving sensitivity in clean environments.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system uses feedback from the environment sensing device to continuously monitor environmental conditions and automatically adjust the sensing threshold accordingly. This closed-loop feedback mechanism enables the touch panel to adapt to changing environmental conditions without manual intervention, resolving the contradiction between reliability and sensitivity.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If manual adjustment of setting values is required to adapt to different environments, then the adaptability is improved, but the ease of operation is decreased

Engineering Contradiction:
Improveenvironmental adaptationVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The touch panel system performs self-adjustment by automatically detecting environmental conditions through the environment sensing device and modifying its own sensing parameters accordingly. This eliminates the need for manual user intervention, maintaining high adaptability while significantly improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The system automatically changes operational parameters (sensing threshold, analysis criteria) based on detected environmental conditions. The control device receives environment data and dynamically adjusts touch sensing parameters to optimize performance for the current environment, providing adaptability without requiring user operation.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If the touch panel operates in high temperature or high RF noise environments, then the versatility is improved, but the measurement precision is decreased

Engineering Contradiction:

Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The touch panel dynamically adjusts its sensing and analysis parameters based on environmental conditions detected by the sensing device. In high temperature or high RF noise environments, the system automatically modifies threshold values and data analysis criteria to compensate for environmental interference, maintaining measurement precision across a wide environmental range.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The environment sensing device provides continuous feedback about environmental conditions (temperature, RF noise levels), enabling the control device to real-time adjust touch sensing parameters. This feedback mechanism ensures that measurement precision is maintained even when operating in previously challenging environments, expanding the usable environmental range.

Inventive Principle:
Principle #23Feedback
