Solution Overview

Problem

Sales racks for fruit and vegetables often face issues with goods falling and require difficult cleaning, especially when a closed version is used, as the lower part is inaccessible and hard to clean.

Innovation Solution

A sales rack design featuring a variable-position panel below the storage area, which can be easily accessed and cleaned, using a bolt/nut device for secure and adjustable attachment to the columns, allowing the panel to be moved along slots for simplified cleaning without additional mechanisms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a closed version of the sales rack is used to prevent goods from falling, then the structural stability is improved, but the accessibility and ease of cleaning the lower part deteriorates

Engineering Contradiction:
Improvestructural stabilityVSAvoidease of cleaning
Core Design Contradiction:
Stability of the object's compositionVSEase of operation

Solution Approach 1:

The panel below the shelf is designed to be movable rather than fixed, allowing it to be tilted forward to access the lower area for cleaning. This dynamic element resolves the contradiction by providing structural stability when closed while enabling easy access when opened.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The front screen is segmented into an upper fixed part and a lower movable panel. This segmentation allows the upper part to provide structural stability and enclosure, while the lower panel can be independently moved to facilitate cleaning of the lower area.

Inventive Principle:
Principle #1Segmentation

2Strength

If a fixed panel is used below the shelf to enclose the area, then the structural integrity is improved, but the ease of maintenance and cleaning deteriorates

Engineering Contradiction:
Improvestructural integrityVSAvoidease of maintenance
Core Design Contradiction:
StrengthVSEase of repair

Solution Approach 1:

The panel is designed with a pivot connection allowing it to be tilted forward for cleaning access, then returned to its original position. This dynamic capability maintains structural integrity while enabling easy maintenance of the lower area.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The panel can be manually tilted and returned to position without requiring additional mechanisms or tools, allowing for simple self-service maintenance of the lower area.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If additional mechanisms are added to make the panel movable for cleaning, then the ease of cleaning is improved, but the device complexity increases

Engineering Contradiction:
Improveease of cleaningVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

A simple pivot connection allows the panel to be tilted forward for cleaning access and then returned to its original position. This minimal mechanical complexity achieves the goal of easy cleaning without adding sophisticated mechanisms.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The panel movement mechanism requires no power source, control systems, or complex actuation - simply manual tilting accomplishes the cleaning access function, minimizing device complexity while maximizing ease of operation.

Inventive Principle:
Principle #25Self-service

AI summary

The sale frame (1) has side portions (2), a rear portion (6) and an increasing support surface (7) for goods container. A diaphragm (10) is provided underneath the support surface. The diaphragm is mounted in a variable position on the side portions. Each side portion is provided with the columns (3) of different height, which are interconnected by a strut (4) that determines the distance between the two columns. The diaphragm is respectively attached to the two opposing columns with the lower height.
