Solution Overview

Problem

Current battery insertion cases lack a limiting and guiding structure, leading to inaccurate alignment during insertion, reduced installation efficiency, increased operational errors, and potential safety risks due to shaking and mechanical stress in frame-type cabinet bodies.

Innovation Solution

A battery cluster design featuring a battery insertion case with a first limiting structure and a battery cabinet body with slot tracks and guiding ribs, along with a second limiting structure, ensuring precise alignment and stable fixation through chamfers and positioning pins, reducing friction and mechanical stress.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Weight of moving object

If a simple frame-type structure is used for the cabinet body, then the weight and manufacturing cost are reduced, but the support and stability are insufficient

Engineering Contradiction:
Improveweight of cabinet bodyVSAvoidstability of cabinet body
Core Design Contradiction:
Weight of moving objectVSStability of the object's composition

Solution Approach 1:

The cabinet body is divided into a frame structure and separate support plates (first support plate and second support plate) that are positioned at different locations to provide distributed support for the battery insertion case, reducing the need for a heavy monolithic structure while maintaining stability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Support is provided not only from the cabinet body frame but also from support plates positioned at different vertical levels (first support plate above the battery insertion case and second support plate below), creating multi-dimensional support that enhances stability without increasing frame weight

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Device complexity

If manual alignment is used during battery insertion case installation, then no additional alignment mechanisms are needed, but installation precision and efficiency are reduced

Engineering Contradiction:
Improvecomplexity of insertion mechanismVSAvoidalignment precision of battery insertion case
Core Design Contradiction:
Device complexityVSManufacturing precision

Solution Approach 1:

Guiding ribs are introduced as intermediary elements that mediate between the battery insertion case and the cabinet body, providing automatic alignment and guidance during insertion without requiring complex mechanical alignment mechanisms or high-precision manual operation

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The guiding ribs enable the battery insertion case to self-align and self-guide during the insertion process, eliminating the need for external alignment tools or complex adjustment mechanisms while achieving high positioning precision

Inventive Principle:
Principle #25Self-service

3Ease of operation

If the battery insertion case is allowed to move freely during insertion, then ease of operation is improved, but installation precision and component safety are reduced

Engineering Contradiction:
Improveease of battery insertionVSAvoidpositioning accuracy of battery insertion case
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The guiding ribs act as intermediary elements that constrain the battery insertion case movement in lateral directions while allowing smooth insertion along the insertion direction, providing both ease of operation and precise positioning simultaneously

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

Disclosed in the present application is a battery cluster, including a battery insertion case (1) and a battery cabinet body (2). An insertion end of the battery insertion case (1) is provided with a first limiting structure. The battery cabinet body (2) is provided with an insertion opening and at least one slots (22). Inner side walls of each of the at least one slots are provided with a slot track (231) and a guiding rib (232). The battery insertion case (1) is inserted through the insertion opening and slides along the slot track (231), an end of the guiding rib (232) close to the insertion opening is provided with a chamfer, and a second limiting structure (A) corresponding to the first limiting structure is provided in each of the at least one slots at an end away from the insertion opening. When the battery insertion case (1) is completely inserted into one of the at least one slots (22) from the insertion opening, the guiding rib (232) is abutted against two sides of the battery insertion case (1), and the first limiting structure and the second limiting structure (A) are limited and fixed to each other.
