Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a universal touch driver is used for all users, then device complexity is reduced and ease of manufacture is improved, but touch input accuracy and user experience deteriorate due to lack of personalization

Engineering Contradiction:
Improveease of manufactureVSAvoidtouch input accuracy
Core Design Contradiction:
Ease of manufactureVSMeasurement precision

Solution Approach 1:

The patent segments the user base into different clusters based on touch input characteristics, and creates customized touch driver profiles for each cluster. This segmentation allows the system to maintain multiple specialized profiles rather than a single universal driver, resolving the contradiction between manufacturing simplicity and measurement precision by organizing complexity in a structured, manageable way.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements dynamic adaptation where the touch driver profile is automatically selected and adjusted based on real-time analysis of user touch characteristics. The system dynamically transitions between different profiles or adjusts parameters within profiles, enabling the touch driver to adapt to individual users without requiring manual reconfiguration, thus maintaining accuracy while managing complexity through automation.

Inventive Principle:
Principle #15Dynamics

2Measurement precision

If personalized touch profiles are created for each user, then touch input accuracy and user experience are improved, but device complexity and processing requirements increase

Engineering Contradiction:
Improvetouch input accuracyVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent applies partial personalization by creating touch driver profiles at the cluster level rather than for every individual user. This partial action approach provides sufficient personalization to achieve high accuracy while avoiding the excessive complexity of fully individualized profiles. The system processes touch data to identify cluster characteristics and applies cluster-level adjustments, which reduces computational burden while maintaining effectiveness.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The system performs self-service by automatically analyzing touch input patterns and generating personalized profiles without requiring manual user input or configuration. The touch driver autonomously adapts to user characteristics by processing touch data and adjusting parameters, which reduces the operational complexity and automation burden on the system while achieving high measurement precision.

Inventive Principle:
Principle #25Self-service

3Measurement precision

If touch calibration is performed manually for each user, then touch input accuracy is improved, but time consumption and productivity are reduced

Engineering Contradiction:
Improvetouch input accuracyVSAvoidcalibration time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary action by pre-processing touch input data to identify user characteristics and generate personalized profiles automatically before actual use. The system analyzes touch patterns and creates calibrated profiles in advance, eliminating the need for time-consuming manual calibration sessions. This preliminary automated analysis achieves high touch input accuracy while minimizing time loss during user setup.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the mechanical manual calibration process with an automated computational system that analyzes touch data and generates profiles algorithmically. Instead of requiring users to manually perform calibration tasks, the system uses software-based analysis and automatic profile generation, which maintains high accuracy while dramatically reducing the time and effort required for calibration.

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

4Ease of operation

If generic touch processing parameters are used, then ease of operation is maintained, but adaptability to different user characteristics deteriorates

Engineering Contradiction:
Improveease of operationVSAvoidadaptability
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent achieves universality by creating a multi-functional touch driver system that can serve multiple user types through cluster-based profiles. The system maintains a set of standardized profiles that can be automatically selected based on user characteristics, providing adaptability to different users while preserving ease of operation. The unified profile selection mechanism allows the system to adapt to various user preferences without requiring complex manual configuration or different operational procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)
