Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional joint connectors with noise reduction members for all terminals result in size and cost increases, and the arrangement of these members cannot be changed after attachment, as they are fixed on the connector side, leading to inefficient noise reduction and potential signal distortion in electric circuits.

Innovation Solution

A connector design featuring a holder with noise reduction member holding rooms that can be adjusted and checked post-attachment, where noise reduction members are only provided for terminals prone to noise, made of ferrite material, allowing flexible arrangement and reduction in unnecessary noise reduction member placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If noise reduction members are provided for all terminals, then noise reduction effect is improved, but connector size and cost increase

Engineering Contradiction:

Improvenoise reduction effectVSAvoidconnector size

Core Design Contradiction:

Object-affected harmful factorsVSVolume of stationary object

Solution Approach 1:

The patent applies local quality by providing noise reduction members only at specific terminals (branch line terminals) where noise occurs, rather than uniformly at all terminals. The holder is designed with selective noise reduction member holding rooms that correspond only to terminals requiring noise reduction, thereby reducing overall connector size while maintaining effective noise suppression where needed.

Inventive Principle:

Principle #3Local quality

2Object-affected harmful factors

If noise reduction members are provided for all terminals, then noise reduction effect is improved, but manufacturing cost increases

Engineering Contradiction:

Improvenoise reduction effectVSAvoidmanufacturing cost

Core Design Contradiction:

Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The holder is designed with a specific number of noise reduction member holding rooms that corresponds to the actual number of terminals requiring noise reduction. This selective configuration reduces the total number of noise reduction members needed, thereby lowering material costs and manufacturing expenses while maintaining effective noise reduction performance.

Inventive Principle:

Principle #3Local quality

3Object-affected harmful factors

If noise reduction members are disposed on connector side, then noise reduction is achieved, but arrangement cannot be changed after attachment

Engineering Contradiction:

Improvenoise reductionVSAvoidarrangement flexibility

Core Design Contradiction:

Object-affected harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent segments the noise reduction function into a separate holder component that is attached to the connector. This modular design allows the holder with noise reduction members to be independently configured and attached, enabling arrangement adjustments before attachment while maintaining effective noise reduction performance.

Inventive Principle:

Principle #1Segmentation

4Object-affected harmful factors

If holder with noise reduction member holding rooms is attached to housing, then noise reduction members can be selectively disposed, but attachment structure complexity increases

Engineering Contradiction:

Improveselective noise reductionVSAvoidattachment structure

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent merges multiple functions into the holder component: it serves as both the mounting structure for noise reduction members and the attachment interface to the connector housing. The holder includes both noise reduction member holding rooms and attachment portions, integrating the noise reduction function and structural attachment function into a single component, thereby simplifying the overall attachment structure.

Inventive Principle:

Principle #5Merging (Combining)
