Solution Overview

Problem

The existing battery connectors occupy significant space, necessitating a larger arrangement for batteries and power consumption devices, which hinders the development of compact structures.

Innovation Solution

The implementation of a battery assembly with a groove on the battery's outer surface to accommodate the second connector, reducing the distance between the battery and the power consumption device body, and incorporating a support structure to facilitate a compact design while ensuring stable and sealed electrical connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Volume of moving object

If traditional battery connectors are used, then electrical connection is achieved, but the connector occupies significant space affecting component arrangement

Engineering Contradiction:
Improvemounting spaceVSAvoidelectrical connection reliability
Core Design Contradiction:
Volume of moving objectVSReliability

Solution Approach 1:

The connector is merged with the battery casing to form an integrated structure. The connector protrudes from the battery case and is electrically connected to the battery cells inside, eliminating the need for separate connector components and reducing overall mounting space while maintaining electrical connection functionality

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The battery case serves multiple functions: it provides structural protection for the battery cells and simultaneously houses the connector structure. The connector-integrated case design allows the same component to fulfill both protective enclosure and electrical connection purposes

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

2Volume of moving object

If connector size is reduced, then mounting space is minimized, but connection stability and sealing may be compromised

Engineering Contradiction:
Improveconnector volumeVSAvoidconnection stability
Core Design Contradiction:
Volume of moving objectVSStrength

Solution Approach 1:

The connector and sealing structure are merged into a unified integrated design. The connector includes built-in sealing elements that prevent moisture and dust ingress, ensuring connection stability without requiring additional separate sealing components that would increase volume

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present application provides a battery, a battery assembly, a power consumption device, a producing method and apparatus of a battery, and relates to the field of batteries. The battery includes a box, a battery cell, and a first connector. The battery cell is disposed in the box. The first connector is electrically connected to the battery cell to output electric energy. An outer surface of the box is provided with a groove, and the first connector is disposed in the groove, so that a second connector of a power consumption device is at least partially located in the groove when butted with the first connector. The groove is configured to set the first connector to avoid the first connector occupying too much space inside the box, and the provision of the groove could also leave space for the butting between the first connector and the second connector. When electric energy of the battery cell needs to be output, the second connector on the power consumption device is butted with the first connector at the position of the groove, and the second connector is partially or completely located in the groove, so that the structure of the power consumption device equipped with the battery is more compact.
