Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brake system for human-powered vehicles is used without an acquisition portion, then the device complexity is reduced, but the braking performance becomes suboptimal
Solution Approach 1:
The acquisition portion collects real-time information about the rotary body (temperature, rotation count, manufacturing data) and brake device (friction member remaining amount, temperature, operating portion input/output), feeding this data to the control portion which adjusts braking force accordingly. This feedback mechanism ensures optimal braking performance by adapting to actual system conditions.
Solution Approach 2:
The patent replaces traditional mechanical braking control with an electronic control system. The control portion electronically processes acquired information and drives the brake device based on processed signals, substituting mechanical linkages with electronic sensing, processing, and actuation components.
2Measurement precision
If sensors and communicators are added to acquire information, then the braking control precision is improved, but the device complexity increases
Solution Approach 1:
The acquisition portion is designed as a multi-functional module that can collect various types of information through different sensors (temperature sensor, rotation sensor, thickness sensor) and communicators. This universal acquisition capability allows the system to gather diverse data (rotary body conditions, brake device status, operating portion inputs) using a unified control architecture, reducing overall system complexity despite multiple sensing functions.
3Adaptability or versatility
If the brake device is driven based on acquired information, then the adaptability of the braking system is improved, but the device complexity increases
Solution Approach 1:
The control portion dynamically adjusts braking force based on real-time acquired information. The system transitions from static braking control to dynamic adaptation, where braking characteristics change continuously according to detected conditions such as temperature variations, rotation counts, and friction member wear levels, enabling the brake system to adapt to different operating scenarios.
