Floating Bracket Layout for Motorcycle Inertial Sensor Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inertial sensor attachment structures in motorcycles do not adequately suppress vibrations from the vehicle body frame, limiting the layout flexibility and requiring separate brackets for ABS and inertial sensors, which increases weight and cost.
Innovation Solution
A floating bracket is used to support both the ABS unit and inertial sensor via vibration-absorbing members, allowing for effective vibration suppression and shared component usage, with the inertial sensor being attached to the back surface and the ABS unit to the top surface of the bracket, and an additional vibration-absorbing member between the sensor and the bracket for enhanced isolation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If vibration absorbing members are used to support the inertial sensor in a floated manner, then vibration transmission is reduced, but the layout flexibility is restricted
Solution Approach 1:
The patent combines the ABS unit and inertial sensor onto a single floating bracket, merging their mounting functions. This integration allows the bracket to be positioned optimally for vibration isolation while accommodating both components, thereby improving layout flexibility without compromising vibration protection.
Solution Approach 2:
The floating bracket serves multiple functions: it mounts both the ABS unit and inertial sensor, provides vibration isolation through floating support, and enables flexible layout configuration. This multi-functionality resolves the contradiction by making the vibration protection system adaptable to different layout requirements.
2Reliability
If separate brackets are used for the ABS unit and inertial sensor, then each component is adequately supported, but the number of components increases, leading to increased weight and cost
Solution Approach 1:
The patent merges the ABS unit and inertial sensor mounting functions into a single floating bracket. This consolidation reduces the total number of components, decreases weight, and lowers cost while maintaining adequate support for both components through the shared bracket structure.
Solution Approach 2:
The floating bracket is designed as a universal mounting structure that can accommodate both the ABS unit and inertial sensor simultaneously. This multi-functional design eliminates the need for separate brackets, thereby reducing component count, weight, and cost while preserving reliable support for each component.
3Object-affected harmful factors
If the floating bracket supports only the inertial sensor, then vibration isolation is achieved, but additional components are required for the ABS unit
Solution Approach 1:
The patent combines the mounting functions for both the inertial sensor and ABS unit onto a single floating bracket. This merger maintains effective vibration isolation for the inertial sensor while eliminating the need for separate ABS unit mounting components, thereby reducing overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces vibration transmission to the inertial sensor, increases layout flexibility, reduces the number of components, and lowers weight and cost by sharing the floating bracket, while maintaining detection accuracy and stability.
Implementation Method 1
a bracket of the inertial sensor is supported by a vehicle body frame in a floated manner via vibration absorbing members. Vibration coming from the vehicle body frame is absorbed by the vibration absorbing members
Implementation Method 2
another vibration absorbing member sandwiched between the inertial sensor and the first attachment surface of the floating bracket. vibration to travel from the ABS unit to the inertial sensor can be suppressed because it is absorbed by the other vibration absorbing member
