Solution Overview

Problem

Smart anti-lost tags, such as Bluetooth and GPS devices, are difficult to locate when placed in bags due to their small size and the lack of specialized packaging that prevents them from falling out, causing inconvenience in finding and securing them.

Innovation Solution

A wallet with an accommodating pocket designed to securely hold the anti-lost tag, featuring a pocket opening and a switch control mechanism to facilitate easy insertion and removal, and optionally including a visible window for visibility and a detachable design for convenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the anti-lost tag is placed in a bag with many miscellaneous items, then the anti-lost tag can be carried conveniently, but it becomes difficult to find the anti-lost tag due to its small size and lack of visibility

Engineering Contradiction:
Improveconvenience of carryingVSAvoiddifficulty of finding the anti-lost tag
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies a transparent or translucent window structure on the accommodating pocket that allows the anti-lost tag to be visually detected through the pocket material. This enables users to locate the tag easily by sight without needing to search through bags or containers, directly resolving the difficulty of finding the tag while maintaining portability

Inventive Principle:
Principle #32Color changes

2Device complexity

If the anti-lost tag is placed in a regular bag without specialized packaging, then the bag structure remains simple, but the anti-lost tag is easy to fall out through the openings

Engineering Contradiction:
Improvesimplicity of bag structureVSAvoidsecurity of retaining the anti-lost tag
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the bag structure into a main body and a separate accommodating pocket component. The pocket is designed with specific opening dimensions that allow insertion of the anti-lost tag but prevent its removal without intentional action. This segmentation enables the bag to retain security functionality while maintaining overall structural simplicity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The accommodating pocket acts as an intermediary component between the bag interior and the anti-lost tag. It provides a controlled interface with specific opening characteristics that mediate between the need for easy access and the need to prevent accidental loss, resolving the contradiction between simple structure and reliable retention

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If the accommodating pocket is designed with a closed structure to prevent the anti-lost tag from falling out, then the retention security is improved, but the ease of inserting and removing the tag deteriorates

Engineering Contradiction:
Improvesecurity of retaining the anti-lost tagVSAvoidease of inserting and removing the tag
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent designs the pocket opening with dynamic characteristics - the opening dimension is fixed to prevent the tag from falling out, but the pocket itself can be detached or opened to allow intentional insertion and removal. This dynamic design resolves the contradiction by providing different states for different operational needs

Inventive Principle:
Principle #15Dynamics

4Shape

If the anti-lost tag is made small in size to be unobtrusive, then the aesthetic appearance is improved, but the ease of locating the tag deteriorates

Engineering Contradiction:
Improvecompact size of the tagVSAvoiddifficulty of locating the tag
Core Design Contradiction:
ShapeVSDifficulty of detecting and measuring

Solution Approach 1:

The patent implements a nested structure where the anti-lost tag is placed inside an accommodating pocket that is itself integrated into or attached to the bag. This nesting arrangement allows the tag to remain small and unobtrusive while the pocket structure provides visual identification capability through transparent or translucent materials, resolving the contradiction between compact size and locatability

Inventive Principle:
Principle #7Nested doll (Nesting)

AI summary

A wallet is provided with an anti-lost card, so as to facilitate the user to track the wallet by the anti-lost card, the anti-lost card can be detachably or permanently placed in a wallet body of the wallet. A positioning module of the anti-lost card can take advantage of existing network of devices, which work as crowdsourced beacons to ping each other in order to determine the location of the missing wallet, so that compatible electronic devices can use an app to identify the approximate location of the missing wallet.
