Pre-assembled Disc Brake Units with Cover-like Securing Elements
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc brake assemblies are prone to damage during transport and storage due to external influences, requiring special tools and knowledge for assembly, leading to high costs and limited installation options.
Innovation Solution
The development of pre-assembled units with securing elements, such as plastic covers, that protect components during transport and assembly, allowing for standard tool installation without specialized knowledge and ensuring settings are retained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If pre-assembled units are provided for easier installation, then ease of assembly is improved, but protection against damage during transport deteriorates
Solution Approach 1:
The securing elements are installed on the assembly before transport, performing the protective function in advance. This preliminary action ensures components are secured against damage during transportation and storage, while allowing easy removal during assembly operations.
Solution Approach 2:
The cover-like securing elements provide protective cushioning for the components before they are exposed to potential damage during assembly. This beforehand protection prevents impacts and damage during transport while being removable when assembly is needed.
2Manufacturing precision
If special tools and knowledge are required for assembly, then manufacturing precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The assembly system is segmented into a pre-assembled functional unit and removable securing elements. This segmentation allows the complex internal components to be pre-assembled with precision at the factory, while the external securing elements provide simple, tool-free attachment and detachment for installation.
3Reliability
If securing elements are provided to protect components, then reliability is improved, but device complexity deteriorates
Solution Approach 1:
The securing elements serve multiple functions: they protect internal components from damage during transport, secure the pre-assembled unit during handling, and provide simple attachment/detachment mechanisms. This multi-functionality improves reliability without adding significant complexity.
