Solution Overview

Problem

Existing inter-battery connection devices for connecting electrode terminals of adjacent batteries are prone to losing the slider, which is necessary for connecting the terminals, leading to incomplete connections.

Innovation Solution

An inter-battery connection device with a housing, a bus bar, and a movable member that moves between a temporary catching position and a final catching position, ensuring the bus bar's clips contact the electrode terminals without requiring a separate slider, thus preventing loss and facilitating connection.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a separate slider is used to press and drive the elastic contact piece, then the electrode terminals can be connected without requiring large operation force, but the slider may be lost during connection work

Engineering Contradiction:

Improveoperation forceVSAvoidloss of slider

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The movable member is integrated with the housing through attachment means (protrusions and recesses), merging the previously separate slider component into the housing structure. This eliminates the risk of loss while maintaining the pressing function on elastic contact pieces

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The movable member acts as an intermediary between the housing and the elastic contact pieces, transferring the pressing force while being securely attached to the housing. This mediator role ensures both ease of operation and prevention of component loss

Inventive Principle:

Principle #24Intermediary (Mediator)

2Device complexity

If the movable member is always attached to the housing, then the component structure is simplified, but the clips cannot avoid contact with electrode terminals during insertion

Engineering Contradiction:

Improvecomponent structureVSAvoidunwanted contact

Core Design Contradiction:

Device complexityVSObject-affected harmful factors

Solution Approach 1:

The movable member is designed to be movable relative to the housing, transitioning between a temporary catching position (avoiding contact) and a final catching position (enabling contact). This dynamic capability allows the system to adapt during the connection process

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The movable member is positioned in the temporary catching position before electrode terminal insertion, preliminarily preventing unwanted contact. After insertion, it moves to the final catching position to enable proper connection

Inventive Principle:

Principle #10Preliminary action

AI summary

An inter-battery connection device for connecting electrode terminals of a plurality of batteries comprises a housing, a bus bar attached to the housing, and a movable member attached to the housing. The bus bar electrically connects two electrode terminals of a pair of batteries adjacent to each other. The bus bar includes a pair of clips each contacting one electrode terminal and a coupling portion connecting the pair of clips. The movable member is movable between a temporary catching position attached to the housing and a final catching position attached to the housing. The movable member has a clip contact avoiding portion preventing contact between one of the clips and the electrode terminal in the temporary catching position and permitting contact between the clip and the electrode terminal during movement from the temporary catching position to the final catching position.
