Solution Overview

Problem

Existing cable connection devices require separate units for different device types and installation scenarios, leading to increased production costs and protrusion outside electrical devices, which can be space-inefficient and costly to manufacture.

Innovation Solution

A modular connection device with a basic housing module and interchangeable stamped part modules, featuring angled stamped parts to reduce height and allow for flexible cable routing, enabling a single device to accommodate various installation situations and device types while minimizing production costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If separate cable junction boxes are manufactured for each different variant of device type, connection contact, and installation, then the connection device can be specifically optimized for each application, but the manufacturing costs increase and the device complexity increases

Engineering Contradiction:
Improveadaptability to different device typesVSAvoidnumber of different cable junction box variants
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent implements a universal cable junction box design where the contact element can be positioned at multiple locations (front, rear, left, right sides) and oriented in different directions. This allows a single basic housing design to serve multiple device types and installation scenarios, eliminating the need to manufacture separate junction boxes for each variant while maintaining specific optimization for each application

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

Solution Approach 2:

The contact element is designed to be movable and repositionable within the housing rather than fixed in a single location. This dynamic capability allows the same junction box to adapt to different connection requirements by repositioning the contact element, providing versatility without requiring multiple static housing designs

Inventive Principle:
Principle #15Dynamics

2Ease of operation

If standard cable connection boxes are used with sufficient height, then adequate space is available for connections, but the boxes protrude beyond the electrical device itself which is space-inefficient

Engineering Contradiction:
Improvespace for cable connectionsVSAvoidprotrusion height of connection box
Core Design Contradiction:
Ease of operationVSLength of stationary object

Solution Approach 1:

Instead of providing connection space primarily in the vertical dimension (protrusion height), the patent utilizes horizontal dimensions by positioning contact elements on the side walls of the housing. This allows adequate connection space to be achieved without increasing the protrusion height, as connections can be made laterally rather than vertically

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Length of stationary object

If the connecting cable is routed horizontally out of the cable entry point, then the connection device maintains a low profile, but separate cable junction boxes are required for different installation scenarios

Engineering Contradiction:
Improveheight of connection deviceVSAvoidflexibility for different cable routing directions
Core Design Contradiction:
Length of stationary objectVSAdaptability or versatility

Solution Approach 1:

The cable entry point and contact element positioning are designed to be adaptable to different routing directions. The contact element can be positioned on any side of the housing and the cable entry can accommodate vertical, horizontal, or angled routing, allowing a single low-profile design to serve multiple installation scenarios without requiring separate junction boxes

Inventive Principle:
Principle #15Dynamics
