Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If wireless communication is used between APP-compatible devices and on-board controllers, then ease of operation is improved, but reliability deteriorates during movement

Engineering Contradiction:
Improveease of operationVSAvoidreliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent uses the on-board controller as an intermediary device that receives commands from the APP-compatible device and executes them locally. The controller stores and processes gearshift commands, acting as a buffer between the wireless communication interface and the mechanical gearshift system, thereby maintaining reliability while enabling wireless operation.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If the system is designed to be compatible with pre-existing bicycles, then adaptability is improved, but device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The on-board controller is designed with multi-functionality to handle various communication protocols (Bluetooth Low Energy, ANT+), store multiple types of data (firmware, parameters, gearshift commands), and interface with different bicycle components. This universal design enables compatibility with pre-existing bicycles while managing complexity through integrated functionality.

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

Solution Approach 2:

The patent implements a nested architecture where the on-board controller contains embedded memory for firmware and parameters, which in turn contains the operational logic for gearshift control. The APP interface module is nested within the controller structure, creating a hierarchical organization that manages complexity through modular nesting.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Adaptability or versatility

If firmware updates and parameter settings are enabled through APP interface, then adaptability is improved, but ease of operation deteriorates due to technical complexity

Engineering Contradiction:
ImproveadaptabilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system implements self-service capabilities where the on-board controller automatically receives and installs firmware updates, and parameters are automatically configured based on APP commands without requiring manual technical intervention. The controller manages its own software maintenance and configuration, simplifying user interaction while maintaining adaptability.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent incorporates feedback mechanisms where the on-board controller communicates system status, firmware version, and parameter settings back to the APP-compatible device. This feedback loop allows the system to automatically adjust and confirm changes, reducing the operational burden on users while maintaining full adaptability through remote configuration.

Inventive Principle:
Principle #23Feedback
