Solution Overview

Problem

Existing angled housing parts for electric connectors are complex, prone to damage during assembly, and not well suited for automated processes, especially when managing wire inserts or exits at angles and requiring multiple elements for sealing against environmental influences.

Innovation Solution

The angled housing part consists of a first section and a second section, which are connected by a deformable bellows section that allows relative movement between the first and second sections, simplifying assembly and enabling automation by maintaining a single integrated housing part.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple separate elements are used to assemble the electric connector, then the sealing and connection functionality is achieved, but the assembly process becomes cumbersome and complex

Engineering Contradiction:
Improvesealing functionalityVSAvoidassembly process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate elements (housing parts, seals, and connection components) into a single integrated housing part. The bellows section integrates the sealing function while the flange surfaces provide connection capability, eliminating the need for separate sealing elements and reducing assembly complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The single integrated housing part performs multiple functions simultaneously: the bellows section provides sealing against environmental influences, the flange surfaces enable connection to complementary parts, and the elastic deformation capability allows for relative movement during assembly. This multi-functionality reduces the number of components needed.

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

2Reliability

If multiple separate elements are assembled together, then the required functionality is achieved, but the assembly time increases and automation becomes difficult

Engineering Contradiction:
Improveconnection stabilityVSAvoidassembly speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

By merging multiple components into a single integrated housing part, the assembly process is simplified from assembling multiple separate elements to installing one component. This significantly reduces assembly time and facilitates automation while maintaining connection stability through the integrated flange surfaces and bellows section.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The housing part is pre-assembled as a single integrated component during manufacturing, with the bellows section and flange surfaces already in their correct positions and configurations. This preliminary integration eliminates the need for time-consuming on-site assembly of multiple elements.

Inventive Principle:
Principle #10Preliminary action

3Manufacturing precision

If multiple separate elements are handled individually during assembly, then precise positioning is possible, but the risk of damaging elements such as seals increases

Engineering Contradiction:
Improvepositioning accuracyVSAvoidelement integrity
Core Design Contradiction:
Manufacturing precisionVSReliability

Solution Approach 1:

The patent combines the sealing element (bellows section) with the housing structure into a single integrated component. This eliminates the risk of damaging separate seals during assembly, as the bellows section is inherently protected within the integrated housing part while maintaining its sealing function and positioning accuracy.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The integrated design inherently protects the bellows section from damage during assembly by incorporating it as part of the rigid housing structure. The bellows section is pre-positioned and protected within the housing part, eliminating the need for separate handling that could cause damage.

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