Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If real-time character recognition is performed on handwriting input using stylus pens, then handwriting input functionality is enhanced, but system resources are consumed and screen output delays occur

Engineering Contradiction:

Improvehandwriting input functionalityVSAvoidscreen output delay

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent applies dynamics by making the recognition period adjustable rather than fixed. The processor dynamically changes the recognition period between a first recognition period and a second recognition period based on detected events, allowing the system to adapt its resource consumption and response time characteristics to different operational contexts, thereby resolving the contradiction between maintaining handwriting input functionality and avoiding screen output delays

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements parameter changes by modifying the recognition period parameter. The processor changes the recognition period from a first value to a second value based on detected events, which directly controls the balance between processing frequency (affecting screen output delay) and resource consumption, thus resolving the technical contradiction

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If real-time character recognition is performed on handwriting input, then character recognition capability is improved, but system resource consumption increases

Engineering Contradiction:

Improvecharacter recognition capabilityVSAvoidsystem resource consumption

Core Design Contradiction:

Measurement precisionVSUse of energy by moving object

Solution Approach 1:

The system dynamically adjusts the recognition period based on detected events, switching between a first recognition period and a second recognition period. This dynamic adjustment allows the processor to optimize the balance between character recognition capability and system resource consumption, performing recognition at higher frequency only when necessary based on event detection

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements periodic action by using different recognition periods for character recognition. Instead of continuous or fixed-period recognition, the system uses variable periodic recognition where the period changes based on events, reducing overall resource consumption while maintaining recognition capability when needed

Inventive Principle:

Principle #19Periodic action
