Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If conventional inertial sensors are used to measure fast rotations, then measurement data can be obtained, but the measurements are not understandable to sport participants and spectators

Engineering Contradiction:

Improverotation measurementVSAvoiddata understandability

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The patent introduces an intermediary processing system that translates raw sensor measurements into sport-specific maneuver identifiers. The system acts as a mediator between the sensor data and human understanding, converting complex rotation measurements into recognizable trick names that participants and spectators can comprehend

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the conventional mechanical understanding of rotation measurements with an information processing system that uses algorithms and databases to translate sensor data into meaningful sport terminology, substituting direct mechanical measurement interpretation with computational analysis

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If subjective judgment is used to evaluate athletic maneuvers, then flexibility in assessment is maintained, but objectivity and consistency are compromised

Engineering Contradiction:

Improvejudging flexibilityVSAvoidjudging objectivity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements an objective feedback system using sensors to provide consistent, measurable data about athletic maneuvers. This feedback mechanism replaces subjective human judgment with reliable sensor-based measurements, ensuring consistency while maintaining the ability to assess various maneuver types through configurable parameters

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent changes the assessment parameters from subjective human perceptions to objective sensor-measured physical quantities such as rotation angles, flight time, and acceleration. This parameter transformation enables reliable, consistent evaluation while maintaining adaptability through configurable threshold values and maneuver definitions

Inventive Principle:

Principle #35Parameter changes

3Loss of information

If manual identification of maneuvers is used, then detailed analysis is possible, but the process is time-consuming and impractical for fast actions

Engineering Contradiction:

Improvemaneuver detail accuracyVSAvoididentification time

Core Design Contradiction:

Loss of informationVSLoss of time

Solution Approach 1:

The patent replaces manual visual identification with an automated sensor-based detection system that continuously monitors athletic maneuvers. This substitution eliminates the time delay of manual analysis while maintaining accurate maneuver identification through real-time sensor data processing

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent implements continuous sensor monitoring that captures athletic maneuvers in real-time without interruption. This continuous data collection ensures no maneuver details are lost while eliminating the time delay associated with manual frame-by-frame analysis, providing immediate and accurate maneuver identification

Inventive Principle:

Principle #20Continuity of useful action
