Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the system responds in real-time to user input, then the writing trajectory is captured accurately, but the system cannot keep up when the user writes too fast, causing breakpoints or illegible trajectories

Engineering Contradiction:
Improvetrajectory recognition accuracyVSAvoidsystem response speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary actions by detecting handwriting trajectories in advance and determining whether they meet predetermined conditions (such as completeness and legibility) before final recognition. Motion parameters are acquired and correction strategies are prepared beforehand, allowing the system to process fast handwriting without losing accuracy.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by evaluating detected trajectories against predetermined conditions and using motion parameters to correct trajectories that don't meet standards. This closed-loop feedback mechanism ensures that even fast handwriting is captured accurately by iteratively improving trajectory quality based on detected issues.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If the system processes all handwriting input in real-time, then responsiveness is maintained, but fast writing causes trajectory loss or illegibility

Engineering Contradiction:
Improveuser writing experienceVSAvoidtrajectory data completeness
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The system uses feedback to evaluate trajectory quality against predetermined conditions and applies corrections based on motion parameters when deficiencies are detected, preventing information loss while maintaining ease of use.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs self-service by automatically detecting trajectory issues and correcting them using motion parameters without requiring user intervention. This self-correction mechanism ensures complete trajectory capture while maintaining smooth user experience.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the system uses basic trajectory detection, then the implementation is simple, but fast handwriting results in breakpoints or illegible trajectories

Engineering Contradiction:
Improvesystem structureVSAvoidtrajectory recognition accuracy
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system applies preliminary action by establishing predetermined conditions for trajectory acceptance and preparing correction strategies in advance. This structured approach improves reliability without significantly increasing complexity, as the framework is set up beforehand and executed systematically.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses parameter changes by incorporating motion parameters (such as speed, acceleration, and direction) to correct trajectories that fail predetermined conditions. This adds reliability through enhanced parameter analysis while maintaining reasonable system complexity through focused parameter monitoring.

Inventive Principle:
Principle #35Parameter changes
