Multi Function Bracket Tolerance Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-function brackets for motor vehicle doors face challenges in providing cost-effective tolerance compensation, leading to noise issues due to backlash between components, especially when the vehicle is in motion and under load.
Innovation Solution
Utilizing the existing elastic seal in the window guide for dual functionality, compressing it between the motor vehicle lock and the carrier to provide tolerance compensation, eliminating the need for additional components and ensuring a noiseless relative movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate components like washers are provided for tolerance compensation, then tolerance compensation is achieved, but production cost increases
Solution Approach 1:
The existing elastic seal in the window guide is made to serve dual functions: its original sealing function and a new tolerance compensation function. By compressing the elastic seal between the motor vehicle lock and the carrier, it compensates for tolerances without requiring separate components like washers, thereby reducing production cost while maintaining reliability
Solution Approach 2:
The elastic seal compensates for tolerances using its own elastic properties without needing additional dedicated components. The seal's inherent elasticity allows it to absorb dimensional variations and prevent backlash, making the system self-sufficient for tolerance compensation
2Ease of manufacture
If loose tolerances are permitted for ease of assembly, then assembly ease is improved, but backlash and noise occur due to relative movement
Solution Approach 1:
The elastic seal's compression state is changed from its normal operating state to a pre-compressed state by positioning it between the motor vehicle lock and the carrier. This parameter change allows the seal to actively compensate for tolerances and prevent backlash, enabling loose assembly tolerances without generating noise
Solution Approach 2:
The invention uses an existing elastic seal that is already part of the window guide structure, rather than adding expensive separate tolerance compensation components. The seal's elastic properties are leveraged to provide continuous tolerance compensation, preventing noise and backlash while maintaining cost-effectiveness
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 approach effectively reduces noise and improves assembly ease while maintaining cost-effectiveness by leveraging the elastic seal's properties for tolerance compensation, ensuring a stable and quiet operation of the motor vehicle door components.
Implementation Method 1
a compensation section of the elastic seal is compressed between a counter structure of the multi function bracket and the motor vehicle lock to provide tolerance compensation

AI summary
A multi function bracket for use in a motor vehicle door with a carrier, and an elastic seal arranged in a window guide for being compressed by a window pane, the carrier comprising a lock receptacle for fastening a motor vehicle lock, and the multi function bracket further comprising a motor vehicle lock fastened to the lock receptacle. The multi function bracket is characterized in that, a compensation section of the elastic seal is compressed between a counter structure of the multi function bracket and the motor vehicle lock to provide tolerance compensation between the carrier and the motor vehicle lock.
