Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing brake disc processing systems face challenges in efficiently transporting and securing brake discs during processing, particularly in maintaining alignment and preventing slipping during grinding operations.
Innovation Solution
A brake disc arrangement with a receiving device that enables a frictional or positive connection with the brake disc, allowing for secure alignment and fixation, utilizing a pressing body and centering device with a spring bias for self-sufficient securing, and a handling section for easy gripping, along with a drive system for rotary driving that applies high torques without influencing the rotary drive.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a brake disc is secured to a receiving device during transport with the friction ring in a vertical plane, then the brake disc remains stable and prevents slipping during grinding operations, but the complexity of the receiving device and drive system increases due to the need for specialized coupling mechanisms and alignment features
Solution Approach 1:
The receiving device is divided into separate functional components: a receiving device for horizontal transport and a drive system for rotational processing. This segmentation allows each component to be optimized independently, reducing overall system complexity while maintaining reliability during both transport and grinding operations.
Solution Approach 2:
A coupling mechanism acts as an intermediary between the receiving device and the drive system. This mediator enables reliable torque transmission during grinding while allowing simple horizontal transport, resolving the contradiction between transport simplicity and processing stability.
2Power
If a coupling mechanism is used to connect the receiving device with a drive system for applying high torques, then high torques can be applied during grinding without influencing the rotary drive, but the device complexity and energy requirements increase
Solution Approach 1:
The system separates the torque application function into a dedicated drive system that couples only when needed. During transport, the receiving device operates independently with simple horizontal movement. During grinding, the coupling mechanism engages to transmit high torques, eliminating the need for a continuously complex system.
Solution Approach 2:
The coupling between the receiving device and drive system is dynamic rather than static. The coupling mechanism can be engaged or disengaged based on operational requirements, allowing the system to transition between simple transport mode and high-torque grinding mode, reducing overall complexity.
3Use of energy by moving object
If the receiving device is designed to be self-sufficient without external energy supply for securing the brake disc, then energy efficiency is improved, but the reliability of securing the brake disc during high torque operations may be compromised
Solution Approach 1:
The receiving device incorporates self-centering features and friction-based securing mechanisms that automatically engage without external energy supply. The horizontal transport orientation and geometric design of the receiving device create inherent stability, allowing reliable brake disc securing through passive mechanical means rather than active energy-consuming systems.
