Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake linings face challenges in reducing heat transfer and noise transmission from the friction surface to the application unit, leading to increased heating and noise during braking.
Innovation Solution
Incorporating an insulation element on the carrier plate, positioned away from the friction lining, which creates an air gap and increases the distance between the friction surface and the application unit, along with features like elevations, grooves, and secure fastening methods to reduce heat conduction and noise, while minimizing material costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the friction lining is directly attached to the carrier plate, then the structural simplicity is improved, but the heat transfer to the application unit increases
Solution Approach 1:
An insulation element is introduced as an intermediary component between the carrier plate and the application unit. This insulation element reduces thermal conductivity from the friction surface through the carrier plate to the application unit, thereby decreasing heat transfer to the application unit while maintaining structural integrity.
2Temperature
If the carrier plate is made thicker to reduce heat transfer, then the thermal insulation is improved, but the weight increases
Solution Approach 1:
The carrier plate is designed as a composite structure combining a thin base layer made of corrosion-resistant material with strategically placed insulation elements. This composite approach provides effective thermal insulation without requiring the entire carrier plate to be thick, thereby minimizing weight increase while achieving the desired thermal protection.
3Temperature
If insulation material is applied over the entire surface, then the thermal insulation is improved, but the material cost increases
Solution Approach 1:
Instead of applying insulation material uniformly across the entire surface, the patent employs insulation elements positioned only in specific regions where heat transfer to the application unit occurs. This localized insulation approach maintains effective thermal protection while significantly reducing the quantity of insulation material required, thereby lowering material costs.
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
The solution effectively reduces heat transfer and noise transmission, achieving cooler operation and quieter braking by decoupling the friction surface from the application unit through strategic insulation placement and design.
Implementation Method 1
The elevation can create an intermediate space between the carrier plate that can be used for air cooling. In addition, the elevation can reduce the heat conduction from the friction surface to the application unit
Implementation Method 2
The insulation element is arranged on the side of the carrier plate that faces away from the friction lining. As a result, the heat transfer from the carrier plate to a clamping unit can be reduced considerably
Implementation Method 3
Cross grooves allow air to flow through between the application units and the insulation elements, thus reducing the heat transfer and cooling the application unit
