Solution Overview

Problem

Existing sales cabinets cannot be easily expanded or reduced in size without replacing them entirely, and spliced cabinets lack internal communication, leading to inefficiencies in storage and retrieval of goods.

Innovation Solution

A combined cabinet is designed as an assembly of single cabinets connected through passage openings, allowing goods to transfer between adjacent units, with features like driving members, adjusting plates, and automatic shutters to facilitate seamless movement and storage adjustments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If the sales space of the existing sales cabinet is expanded by replacing it with a larger one, then the storage capacity is improved, but the cost and complexity of replacement increases

Engineering Contradiction:
Improvestorage capacityVSAvoidreplacement complexity
Core Design Contradiction:
Quantity of substanceVSDevice complexity

Solution Approach 1:

The sales cabinet is divided into multiple independent single cabinets that can be assembled together. Each single cabinet maintains independent functionality while being capable of connecting with others through passage openings, allowing flexible expansion of storage capacity without replacing the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Each single cabinet is designed with universal connection features including passage openings and driving members that enable it to function both independently and as part of a combined system. This multi-functionality allows the same modular unit to serve different purposes based on configuration needs.

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

2Quantity of substance

If two sales cabinets are spliced together to expand sales space, then the storage capacity is improved, but the internal communication between cabinets is lost

Engineering Contradiction:
Improvestorage capacityVSAvoidinternal communication
Core Design Contradiction:
Quantity of substanceVSEase of operation

Solution Approach 1:

The cabinet system is segmented into modular single cabinets, each equipped with its own driving member and passage openings. This segmentation allows each unit to maintain its operational independence while enabling connection to other units, preserving internal communication capabilities within the combined system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Passage openings serve as intermediary channels between adjacent single cabinets, allowing goods to be transferred from one cabinet to another. The driving member acts as a mediator that pushes goods into these passage openings, facilitating communication and goods transfer between previously isolated cabinet units.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a fixed-size sales cabinet is used, then the device complexity is reduced, but the adaptability to different storage needs is limited

Engineering Contradiction:
Improvecabinet structureVSAvoidstorage configuration flexibility
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The cabinet system is divided into standardized single cabinet modules that can be assembled in various configurations. This segmentation maintains simple, repeatable unit structures while enabling flexible adaptation to different storage requirements through combinations of these modules.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The cabinet system transitions from a fixed structure to a dynamic, reconfigurable system. Single cabinets can be connected or disconnected, and passage openings can be opened or closed, allowing the overall system to adapt its configuration based on changing storage needs while maintaining simple individual component designs.

Inventive Principle:
Principle #15Dynamics

AI summary

A combined cabinet is formed by assembling single cabinets. Every two adjacent single cabinets can be communicated with each other by means of a first port, and goods in each single cabinet can enter an adjacent single cabinet by means of the first port. The combined cabinet is further provided with a storage board, a drive element, an automatic door, and an adjustment board in each single cabinet. The drive element is used for pushing the goods to leave the storage board, the adjustment board is used for guiding the goods, and the automatic door is used for opening or closing the first port. The combined cabinet can be designed to be fan-shaped, spherical, crushed stone-like, stacked, corner-like, etc.
