Solution Overview

Problem

Existing multi-coupler connectors face challenges with large dimensions and complex assembly procedures due to rigid rocker arms, which hinder their use in applications requiring compact designs and simplified assembly.

Innovation Solution

A multi-coupler connector design featuring a rocker arm with rotatable end portions that can be inserted through coupler seats, allowing for reduced space requirements and simplified assembly, with a main housing body that can be made in a single piece without assembly windows, and a mechanism where the rocker arm is fixed to a rotation shaft through these seats.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a rigid rocker arm is used in multi-coupler connectors, then the structural strength and reliability are improved, but the overall dimensions increase and assembly complexity increases

Engineering Contradiction:
Improvestructural reliabilityVSAvoidoverall dimensions
Core Design Contradiction:
ReliabilityVSVolume of moving object

Solution Approach 1:

The rocker arm is divided into multiple segments that can rotate relative to each other around a rotation axis. Each segment can be independently positioned, allowing the mechanism to achieve the necessary rock­ing motion while occupying less space. The segmented structure maintains structural integrity through controlled rotational joints rather than requiring a single rigid piece.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rotatable segments of the rocker arm are arranged to nest within each other during rotation, with each segment able to occupy a compact position relative to the others. This nesting arrangement allows the rocker arm mechanism to fit within a smaller overall volume while still providing the full range of motion needed for actuating multiple couplers.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If a rigid rocker arm is used in multi-coupler connectors, then the structural strength is improved, but the assembly procedure becomes more complex

Engineering Contradiction:
Improvestructural strengthVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The rocker arm is divided into multiple segments that can rotate relative to each other around a rotation axis. Each segment can be independently positioned, allowing the mechanism to achieve the necessary rock­ing motion while occupying less space. The segmented structure maintains structural integrity through controlled rotational joints rather than requiring a single rigid piece.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The rocker arm transitions from a static rigid structure to a dynamic segmented structure where each segment can rotate independently. This dynamic configuration allows the assembly to be more flexible during installation and operation, reducing assembly complexity while maintaining the structural strength needed for reliable coupling operations.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If assembly windows are added to the main housing body for insertion, then the assembly procedure is simplified, but the device complexity and production costs increase

Engineering Contradiction:
Improveassembly easeVSAvoidhousing structure complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

Instead of adding assembly windows to the housing body to facilitate insertion, the invention inverts the approach by designing the rocker arm segments to be insertable through the existing coupling seats. The segments are fed through the seats and then positioned and fixed, eliminating the need for additional windows while simplifying the overall housing structure.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The coupling seats serve multiple functions: they house the couplers and also serve as insertion paths for the rocker arm segments. This multi-functionality eliminates the need for separate assembly windows, reducing housing complexity and production costs while maintaining ease of assembly.

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