Molded Battery A/S Label Integration

Solution Overview

Problem

Conventional battery A/S labels are prone to separation and arbitrary exchange or modification by users, leading to inaccurate determination of battery malfunctions and potential damage.

Innovation Solution

An A/S label is integrated into a plastic molded body of the battery, with a portion exposed and the circumferential portion buried, preventing separation or arbitrary exchange during manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the A/S label is attached to the outside of the battery or to a part inside the battery case with an opening hole, then the label is easily accessible for observation, but the label can be easily separated and lost by contact with water and arbitrarily exchanged or modified by users

Engineering Contradiction:

ImproveAccessibility of A/S labelVSAvoidIntegrity of A/S label

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The A/S label is merged with the battery case structure by being disposed within the molded body. The label is positioned such that it is embedded in the plastic material, with only the necessary portion exposed for observation. This integration prevents the label from being easily removed or exchanged while maintaining its accessibility for A/S determination.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The A/S label is nested within the battery case structure. The label is placed inside the molded body of the case, with portions of the label embedded in the plastic material. This nesting approach allows the label to be protected within the case structure while still being observable through strategically exposed portions.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Illumination intensity

If the A/S label is attached to the outside of the battery, then the label is easily observable, but the label is prone to separation and loss when contacting water

Engineering Contradiction:

ImproveVisibility of A/S labelVSAvoidWater contact damage

Core Design Contradiction:

Illumination intensityVSObject-affected harmful factors

Solution Approach 1:

The A/S label is merged with the battery case structure by being disposed within the molded body. The label is positioned such that it is embedded in the plastic material, with only the necessary portion exposed for observation. This integration prevents the label from being easily removed or exchanged while maintaining its accessibility for A/S determination.

Inventive Principle:

Principle #5Merging (Combining)

3Reliability

If the A/S label is disposed inside the battery case, then the label is protected from water contact, but the label may be difficult to observe and access

Engineering Contradiction:

ImproveProtection of A/S labelVSAvoidAccessibility of A/S label

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The A/S label is nested within the battery case structure. The label is placed inside the molded body of the case, with portions of the label embedded in the plastic material. This nesting approach allows the label to be protected within the case structure while still being observable through strategically exposed portions.

AI summary

A label indicating exposure to water is disposed in a plastic member of the battery. The label is prevented from being separated and disappeared and from being exchanged or modified arbitrarily by a battery user by having an edge of the label molded to the battery case.
