Solution Overview

Problem

Existing solutions for attaching support elements in refrigerators, freezers, and wine storage cabinets are either difficult to install or do not provide a secure, reliable fixation, often requiring increased material costs and installation effort.

Innovation Solution

A holding device with an elastically deformable leg and a web structure that securely attaches to the cabinet, allowing for easy assembly and detachment of support elements, featuring an insertion opening and recess to encompass the web, and additional surfaces for optimal guidance and insertion limitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If support elements are permanently installed in the cabinet, then reliability of fixation is improved, but adaptability and ease of removal deteriorate

Engineering Contradiction:
Improvefixation reliabilityVSAvoiddetachability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The holder incorporates an elastically deformable leg that can dynamically change its state between engaged and disengaged positions. During insertion, the leg deforms elastically to accommodate the web, then springs back to lock the support element securely. For removal, the leg is pressed to deform again, releasing the lock. This dynamic elastic behavior enables the system to provide both strong fixation during use and easy removal when needed.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The elastic leg changes its physical state (deformed vs. undeformed) to control the locking mechanism. When undeformed, the leg allows the support element to be inserted; when deformed by the insertion force, it encompasses the web to create a secure lock. This parameter change in the leg's shape enables transition between detachable and reliably fixed states.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If furniture fittings with screws are used in recesses, then fixation reliability is improved, but device complexity and installation effort increase

Engineering Contradiction:
Improvefixation reliabilityVSAvoidassembly complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention extracts the complex screw and furniture fitting components from the system, replacing them with a simple elastic leg mechanism that integrates directly into the holder. The elastic leg provides reliable fixation through its material properties and geometric design rather than through additional fastening components, thereby reducing device complexity while maintaining fixation reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The elastic leg is self-contained within the holder and requires no external screws, nuts, or separate fixing components. The leg's elasticity and geometry enable it to automatically lock onto the web when the support element is inserted, providing self-service fixation without requiring additional assembly steps or complex installation procedures.

Inventive Principle:
Principle #25Self-service

3Ease of operation

If grooves or guides are molded into cabinet walls, then ease of insertion is improved, but fixation reliability deteriorates as support elements can be loosely removed

Engineering Contradiction:
Improveease of insertionVSAvoidfixation reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The invention merges the guiding function and the locking function into a single integrated mechanism. The web serves as both the guide surface and the locking element, while the elastic leg provides both insertion assistance and secure fixation. This combination eliminates the need for separate grooves or guides that would only provide loose retention, achieving both ease of insertion and reliable fixation through one unified system.

Inventive Principle:
Principle #5Merging (Combining)

4Ease of manufacture

If holes are made in cabinet walls for pin insertion, then ease of installation is improved, but fixation reliability and structural integrity deteriorate

Engineering Contradiction:
Improveease of installationVSAvoidfixation reliability
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The web acts as an intermediary element that transfers the loading from the support element to the cabinet structure without requiring holes in the cabinet wall. The web is anchored to the cabinet (e.g., via adhesive or surface mounting) and provides a secure attachment point for the elastic leg, thereby maintaining fixation reliability while avoiding structural compromise of the cabinet wall.

Inventive Principle:
Principle #24Intermediary (Mediator)
