Motorcycle Brake Controller Vibration Resistance via Folded Coupling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional brake hydraulic pressure controllers for motorcycles experience unstable electrical connections due to vibrations during vehicle travel or motor operation, leading to reduced vibration resistance.
Innovation Solution
A brake hydraulic pressure controller design featuring a metal piece connecting motor terminals and a circuit board with specific coupling sections and tongue pieces, forming a slit-shaped clearance for the terminal insertion, enhances vibration resistance by absorbing vibrations through folded middle sections of the coupling sections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a motor and circuit board are connected via conventional rigid electrical connection, then the electrical connection is simple and reliable under static conditions, but the connection becomes unstable when vibrations occur during vehicle travel or motor operation
Solution Approach 1:
The patent employs a flexible printed circuit board (FPC) instead of a rigid circuit board to connect the motor terminals. The FPC can elastically deform to absorb vibrations from vehicle travel and motor operation, preventing disconnection or instability of the electrical connection while maintaining reliable electrical contact between the motor and control unit
Solution Approach 2:
The patent incorporates vibration-absorbing structures such as rubber dampers or elastic mounting elements between the motor assembly and the control unit housing. These cushioning elements are pre-installed to mitigate the impact of vibrations before they can affect the electrical connection, ensuring stable operation under vibrational conditions
2Device complexity
If the motor is directly mounted on the circuit board housing, then the device complexity is reduced, but the vibration resistance deteriorates due to direct transmission of vibrations
Solution Approach 1:
The patent introduces an intermediate vibration-absorbing layer or damping material between the motor mounting surface and the circuit board housing. This intermediary element decouples the direct mechanical connection, preventing vibration transmission while maintaining the compact integrated structure, thus achieving both simplicity and vibration resistance
