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

VSEngineering 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

Engineering Contradiction:
Improveease of assemblyVSAvoiddamage during transport
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

2Manufacturing precision

If special tools and knowledge are required for assembly, then manufacturing precision is improved, but ease of manufacture deteriorates

Engineering Contradiction:
Improveassembly precisionVSAvoidease of assembly
Core Design Contradiction:
Manufacturing precisionVSEase of manufacture

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.

Inventive Principle:
Principle #1Segmentation

3Reliability

If securing elements are provided to protect components, then reliability is improved, but device complexity deteriorates

Engineering Contradiction:
Improveprotection reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)
