Solution Overview

Problem

The existing housings for connecting cable strands to connection pads on electrical contacts are difficult to use due to the manual soldering process, which requires routing the cable through holes and often necessitates additional components for positioning and routing, making the connection process cumbersome.

Innovation Solution

A housing design featuring a holder with a C-shaped holding section and an adjacent open-top cable guide allows easy insertion and secure positioning of the cable strand, with the connection pad directly adjacent to the guide, enabling self-retention and simplified soldering by utilizing a C-shaped cable clamp and elongated guide sections that form a channel for the cable.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual soldering with cable routing through holes is used, then electrical connection is achieved, but assembly complexity increases and ease of operation deteriorates

Engineering Contradiction:
Improveease of cable connectionVSAvoidassembly complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The housing is divided into distinct functional sections: a cable guide section for routing the cable, a holding section for securing the cable, and a connection pad area for electrical connection. This segmentation allows each section to perform its specific function independently, simplifying the overall assembly process and improving ease of operation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cable guide acts as an intermediary component between the cable entry and the connection pad. It provides a dedicated pathway that guides the cable strand directly to the connection position, eliminating the need for complex routing through holes and additional positioning components.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If additional components for cable positioning and routing are provided, then cable routing is improved, but device complexity increases

Engineering Contradiction:
Improvecable positioning and routingVSAvoidnumber of components
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cable guide and holding section are merged into a single integrated structure formed as one piece with the housing. This combination eliminates the need for separate cable positioning components such as grommets, plugs, or additional guide elements, thereby reducing device complexity while maintaining effective cable routing and positioning.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The holding section serves multiple functions: it secures the cable outer sheath, positions the cable strand, and provides structural support for the connection pad. This multi-functionality reduces the need for additional specialized components, simplifying the overall device structure.

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

3Ease of operation

If cable strand is pushed through holes and soldered, then electrical connection is established, but ease of operation deteriorates

Engineering Contradiction:
Improvecable connection processVSAvoidease of assembly
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The cable guide is pre-formed with the exact trajectory needed to lead the cable strand directly to the connection pad. This preliminary preparation of the routing path eliminates the need for manual positioning and alignment during assembly, making the connection process easier and more consistent.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The holding section is designed to automatically secure the cable strand in the correct position once inserted. The structural design provides self-retention, where the cable naturally positions itself against the connection pad without requiring additional adjustment or positioning actions by the assembler.

Inventive Principle:
Principle #25Self-service
