Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple support modes are provided with fixed manufacturer-defined sequences, then the device complexity is reduced and ease of manufacture is improved, but the adaptability to different user preferences and conditions deteriorates
Solution Approach 1:
The patent implements dynamic sorting of support modes based on key performance indicators (KPIs) that are calculated in real-time. The control unit automatically reorders the sequence of support modes according to their calculated KPI values, transforming a static manufacturer-defined sequence into a dynamic user-adapted sequence. This allows the system to adapt to different user preferences and riding conditions without requiring manual reconfiguration or increasing manufacturing complexity.
Solution Approach 2:
The patent changes the parameter of support mode sequence from a fixed manufacturer-defined order to a variable order based on calculated KPIs. By introducing KPI calculation and sorting mechanisms, the system transforms the static parameter into a dynamic one that automatically adjusts based on performance data, thereby improving adaptability while maintaining ease of manufacture through automated control.
2Device complexity
If support modes are pre-configured by manufacturers with fixed sequences, then the device complexity is reduced, but the ease of operation for customization deteriorates
Solution Approach 1:
The patent enables the support mode sequence to self-adjust based on automatically calculated KPIs. The control unit performs the sorting operation autonomously without requiring user intervention or complex manual configuration. The system serves itself by automatically optimizing the support mode sequence according to performance data, thereby improving ease of operation while keeping device complexity low through automated self-configuration.
Solution Approach 2:
The patent performs preliminary calculation of KPIs for each support mode before presenting them to the user in sorted order. By pre-calculating the performance indicators and automatically sorting the modes beforehand, the system eliminates the need for users to manually evaluate and rank multiple support modes, significantly improving ease of operation while maintaining simple device architecture.
3Adaptability or versatility
If users can manually evaluate and rank support modes based on personal preferences, then the adaptability improves, but the loss of time for configuration increases
Solution Approach 1:
The patent replaces the manual mechanical process of user evaluation and ranking with an automated electronic KPI calculation and sorting system. The control unit automatically computes performance indicators and orders support modes based on these calculations, eliminating the time-consuming manual evaluation process while maintaining full adaptability to user preferences through objective performance data.
Solution Approach 2:
The patent implements a feedback mechanism where KPIs are calculated based on objective performance data from each support mode. This feedback loop allows the system to automatically determine the optimal sequence without requiring users to spend time on subjective evaluation. The calculated KPIs provide immediate, objective feedback that enables rapid automatic sorting, thereby reducing configuration time while maintaining adaptability.
4Reliability
If the sequence of support modes is fixed, then the reliability of manufacturer specifications is maintained, but the adaptability to different riding conditions deteriorates
Solution Approach 1:
The patent transforms the static fixed sequence into a dynamic sequence that automatically adapts to different riding conditions through real-time KPI calculation and sorting. The control unit maintains reliability by using objective, calculable performance indicators while simultaneously achieving adaptability by reordering modes based on current conditions and user preferences, resolving the contradiction between fixed specifications and flexible adaptation.
