Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing terminals have fixed inner diameters, which limits their compatibility with binding posts of different outer diameters, leading to poor connections and potential electrical hazards, especially for non-professionals who lack the tools to modify or replace them.

Innovation Solution

A structure using spacers with clamping mechanisms and eccentric connecting holes that can be adjusted to match binding posts of varying diameters, allowing for a stable and secure connection without altering the terminal or binding post structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If terminals have fixed inner diameters, then manufacturing and structure are simple, but adaptability to binding posts of different diameters is poor

Engineering Contradiction:

Improveadaptability to binding postsVSAvoidterminal structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The terminal structure is made adjustable through the rotation mechanism. The connecting holes can change their relative position by rotating the terminal body, allowing the inner diameter to be dynamically adjusted to match different binding post diameters. This transforms a static structure into a dynamic one that can adapt to various conditions.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The inner diameter parameter of the terminal is made changeable through the rotation mechanism. By rotating the terminal, the distance between connecting holes changes, thereby changing the effective inner diameter to match different binding post sizes. This allows a single terminal to serve multiple diameter requirements.

Inventive Principle:

Principle #35Parameter changes

2Ease of operation

If binding posts have inappropriate outer diameters, then connection compatibility is poor, but for non-professionals, the ease of operation to modify or replace terminals is difficult

Engineering Contradiction:

Improveease of modificationVSAvoidconnection stability

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The terminal incorporates a self-adjusting rotation mechanism that allows users to modify the inner diameter without external tools or professional assistance. The user can simply rotate the terminal body to adjust the connecting hole positions, enabling self-service modification while maintaining connection reliability through the secure rotation locking mechanism.

Inventive Principle:

Principle #25Self-service

3Loss of time

If the inner diameter of terminals is fixed, then manufacturing cost is low, but the loss of time for re-purchasing wires when diameter mismatch occurs is high

Engineering Contradiction:

Improvetime for wire replacementVSAvoidterminal structure

Core Design Contradiction:

Loss of timeVSDevice complexity

Solution Approach 1:

The terminal is designed with multi-functionality through the rotation mechanism, allowing a single terminal to accommodate multiple binding post diameters. This universal design eliminates the need to purchase different terminals or wires for different diameter requirements, saving time and reducing waste.

Inventive Principle:

Principle #6Universality (Multi-functionality)
