Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lighting and safety systems are used for electric bicycles, then the system structure is simple, but the effectiveness in enhancing rider safety is insufficient
Solution Approach 1:
The safety system is divided into multiple independent sensor modules (friction sensors, temperature sensors, pressure sensors) that can detect different parameters separately. Each sensor module is independently configurable and can be activated based on specific riding conditions, allowing the system to achieve high reliability without requiring all sensors to function simultaneously, thus managing complexity.
Solution Approach 2:
The controller is designed to perform multiple functions: it processes data from various sensor types (friction, temperature, pressure), determines rider input based on multiple parameters, controls different output devices (display, haptic feedback, lighting), and adapts to different riding conditions. This multi-functionality consolidates what could be multiple separate systems into a single integrated controller, improving reliability while managing complexity.
2Reliability
If multiple sensors and adaptive systems are integrated to detect hazards, then rider safety is improved, but the device complexity increases
Solution Approach 1:
The friction sensor, temperature sensor, and pressure sensor are integrated into a single coordinated system managed by one controller. These sensors work together to detect hazardous conditions, and their data is processed collectively to determine rider input and trigger appropriate responses. This merging reduces the complexity that would arise from having completely separate detection and control systems.
Solution Approach 2:
The system automatically determines rider input by analyzing sensor data without requiring direct rider interaction. The controller autonomously processes friction, temperature, and pressure information to identify hazardous conditions and triggers appropriate safety responses (display alerts, haptic feedback, lighting changes) without needing additional rider input devices, reducing overall system complexity.
3Measurement precision
If friction detection systems with multiple sensor types are implemented, then measurement precision is improved, but the ease of manufacture decreases
Solution Approach 1:
Different sensor types (friction, temperature, pressure) are deployed at specific locations where they are most effective for detecting particular aspects of traction conditions. Each sensor targets a specific measurement need, and the controller processes these localized measurements collectively to achieve comprehensive and precise traction condition detection while allowing for modular assembly.
