Solution Overview

Problem

Conventional tool cabinets require external audio devices for music playback, occupying additional space and being inconvenient for users who want to listen to music while working.

Innovation Solution

Integration of an audio device within the tool cabinet, featuring a movable receiving member with a coupling opening that allows the audio device to be securely housed and exposed for sound output, enabling wireless connectivity and space-efficient music playback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If an external audio device is used for music playback at the workplace, then music playback functionality is achieved, but additional space is occupied and convenience is reduced

Engineering Contradiction:
Improvemusic playback functionalityVSAvoidspace occupation
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The audio device is integrated into the tool cabinet by engaging it with a coupling opening formed in the cabinet body or cover body. The audio device is received within the cabinet's internal space, merging the storage function and audio playback function into a single unit, thereby eliminating the need for separate external audio equipment and reducing space occupation.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If an external audio device is used for music playback, then music can be played, but user convenience is reduced due to setup and space requirements

Engineering Contradiction:
Improvemusic playback capabilityVSAvoiduser convenience
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By integrating the audio device directly into the tool cabinet structure, the system eliminates the need for separate setup and placement of external devices. The audio device becomes part of the cabinet itself, making it immediately accessible and convenient for users who want to listen to music while working at the cabinet.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the cover body is made movable to open and close the receiving space, then accessibility to stored items is improved, but the structural complexity increases

Engineering Contradiction:
Improveaccessibility to stored itemsVSAvoidstructural complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cabinet is divided into a stationary cabinet body and a movable cover body that can open and close relative to each other. This segmentation allows the cover body to be independently movable, providing easy access to the receiving space and stored items while keeping the rest of the cabinet structure simple and stable.

Inventive Principle:
Principle #1Segmentation

AI summary

A tool cabinet includes a cabinet unit and an audio device. The cabinet unit includes a cabinet body and at least one receiving member. The receiving member has a cover body and a bottom wall. The cover body is movably connected to the cabinet body. The bottom wall cooperates with the cover body to define a receiving space therebetween. The cover body is movable relative to the cabinet body to open and close the receiving space. One of the cabinet body and the cover body is formed with a coupling opening in communication with the receiving space. The audio device engages the coupling opening, is received in the receiving space, and has a sound output surface exposed from the coupling opening.
