Solution Overview

Problem

Existing battery packs require additional components and processes to support battery cells, which can increase complexity and thickness, and often rely on tapes that degrade the appearance and functionality.

Innovation Solution

A battery pack design featuring a frame with curved supporting portions that integrate with the battery cells, eliminating the need for additional tapes and allowing for a thinner, more stable configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If additional components such as tapes are used to support battery cells, then the battery cells can be fixed and supported, but the number of components increases and the device thickness increases

Engineering Contradiction:

Improvebattery cell support stabilityVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The supporting portions are integrated directly into the frame structure, merging the support function with the frame body. This eliminates the need for separate support components like tapes, thereby reducing component count while maintaining support stability.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The support function is extracted from separate components (tapes) and incorporated into the frame itself through protruding supporting portions, eliminating the need for additional fastening materials.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If additional components such as tapes are used to support battery cells, then the battery cells can be fixed and supported, but the device thickness increases

Engineering Contradiction:

Improvebattery cell support stabilityVSAvoiddevice thickness

Core Design Contradiction:

ReliabilityVSLength of stationary object

Solution Approach 1:

The supporting portions are formed as integral parts of the frame, combining the frame structure with the support function. This eliminates the need for additional thickness from separate support components while maintaining adequate support capability.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If curved surfaces are used for supporting portions, then the battery cells are more stably supported and appearance is improved, but the manufacturing complexity increases

Engineering Contradiction:

Improvebattery cell support stabilityVSAvoidmanufacturing process simplicity

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The supporting portions feature curved surfaces that conform to the battery cell edges, providing stable support and improved appearance. The curvature is designed to be simple enough for conventional manufacturing processes.

Inventive Principle:

Principle #14Spheroidality (Curvature)

Solution Approach 2:

The curved supporting portions are integrated into the frame as a single molded part, combining the frame structure with the curved support surfaces. This eliminates separate manufacturing steps for support components while achieving the desired curvature.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

Provided is a battery pack. The battery pack includes battery cells, and a frame including a frame main body having assembling openings for accommodating the battery cells, and supporting portions protruding from the frame main body toward the assembling openings to support edges of the battery cells, wherein supporting surfaces of the supporting portions are formed as curved surfaces. By improving a supporting structure of the battery cells, the number of components and processes may be reduced, and the battery pack may be formed thin.
