Solution Overview

Problem

Existing electrical devices face cumbersome wiring operations, excessive cable consumption, and large space occupation due to the complex internal wiring logic of positive and negative cables being combined separately before connection to a direct current switch.

Innovation Solution

A connector for wiring that integrates a wire-end assembly, a board-end assembly, and a combiner assembly, allowing for the direct electrical connection of multiple board-end parts of the same polarity to a single wiring cable, reducing the need for external convergence cables and simplifying operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If separate combination of positive and negative cables is performed before connection to direct current switch, then electrical connection functionality is achieved, but wiring operation becomes cumbersome and cable consumption increases

Engineering Contradiction:
Improveelectrical connection functionalityVSAvoidwiring operation
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent combines the combination functions for positive cables and negative cables into a single connector body. The connector includes a first combination component for combining multiple positive cables and a second combination component for combining multiple negative cables, both integrated within the same connector structure. This allows simultaneous combination of both polarities in one operation, eliminating the need for separate combination steps and reducing wiring complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The connector is designed as a multi-functional device that can simultaneously perform multiple functions: combining positive cables, combining negative cables, and providing direct current switch connection. The connector body integrates multiple combination components that can handle different cable polarities and configurations, making a single connector replace multiple separate components and simplify the overall wiring system.

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

2Reliability

If separate combination of positive and negative cables is performed using multiple connectors, then electrical connection is achieved, but cable consumption becomes excessive

Engineering Contradiction:
Improveelectrical connectionVSAvoidcable consumption
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The patent merges the functionality of multiple separate connectors into a single integrated connector. The first combination component and second combination component are both housed within the same connector body, allowing positive and negative cables to be combined simultaneously. This integration eliminates the need for additional connectors and reduces the total amount of cable required for connections.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If separate combination of positive and negative cables is performed, then electrical connection functionality is achieved, but space occupation inside electrical device becomes large

Engineering Contradiction:
Improveelectrical connection functionalityVSAvoidspace occupation
Core Design Contradiction:
ReliabilityVSVolume of stationary object

Solution Approach 1:

The patent combines multiple combination functions into a single compact connector structure. The first combination component for positive cables and the second combination component for negative cables are integrated within the same connector body, significantly reducing the space required compared to using separate connectors for each combination function. This compact integration optimizes the use of internal space in electrical devices.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If multiple separate connectors are used for cable combination, then electrical connection is achieved, but device complexity increases

Engineering Contradiction:
Improveelectrical connectionVSAvoidwiring structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent integrates multiple combination functions into a single connector with a unified structure. The connector body houses both the first combination component for positive cables and the second combination component for negative cables, along with corresponding connection terminals. This integration simplifies the wiring structure by reducing the number of separate components and their interconnections, making the overall system less complex while maintaining full electrical connection functionality.

Inventive Principle:
Principle #5Merging (Combining)
