Solution Overview

Problem

Existing built-in refrigeration appliances with dispensing openings face challenges in aligning decorative panels with adjacent furniture fronts, requiring adjustable frames that are often costly and wasteful, as they need to be customized for different panel thicknesses, and risk damage during installation.

Innovation Solution

A frame part comprising a cover part and an inner sleeve, where the inner sleeve can be adjusted in length to fit different decorative panel thicknesses, with optional telescopic engagement and latching mechanisms to ensure secure assembly without noticeable gaps, allowing for universal use and reduced material waste.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a frame part with a predetermined breaking point is used to adapt to different decorative panel thicknesses, then the frame part can be shortened for weaker furniture fronts, but the frame part requires manual adjustment and customization in most cases

Engineering Contradiction:
Improveadaptability to different panel thicknessesVSAvoidease of installation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The frame part is divided into two separate components: an outer sleeve and an inner sleeve. The inner sleeve can be inserted into the outer sleeve to extend the overall length, allowing the same frame part to accommodate different panel thicknesses without manual shortening or customization.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner sleeve is nested within the outer sleeve, with the inner sleeve having a length compensating for the difference in thickness between thin and thick decorative panels. This nesting arrangement allows the frame part to be used in the assembled state with both thin and thick panels without adjustment.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Adaptability or versatility

If a frame part with a predetermined breaking point is manufactured, then it can accommodate weaker furniture fronts, but material is wasted in production

Engineering Contradiction:
Improveadaptability to different panel thicknessesVSAvoidmaterial waste
Core Design Contradiction:
Adaptability or versatilityVSLoss of substance

Solution Approach 1:

The frame part is segmented into an outer sleeve and an inner sleeve, each manufactured to standard lengths. This eliminates the need to manufacture oversized frame parts with breaking points, as the inner sleeve is only added when needed to extend the length for thick panels.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The overall length of the frame part is changed by adding or omitting the inner sleeve, rather than manufacturing frame parts with different predetermined lengths. This allows the same outer sleeve to be used for both thin and thick panels, reducing material waste in production.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If a frame part with a predetermined breaking point is used, then it can be shortened for weak decorative panels, but the frame part is at risk of damage during shortening

Engineering Contradiction:
Improveadaptability to different panel thicknessesVSAvoidrisk of damage during installation
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The frame part is segmented into two separate sleeves that are assembled together. This eliminates the need to shorten the frame part by breaking it, as the inner sleeve is simply inserted into the outer sleeve to achieve the required length extension.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The inner sleeve is nested within the outer sleeve, providing a damage-free method to extend the frame part length. The sleeves are connected through telescopic engagement with latching mechanisms, ensuring secure assembly without the risks associated with breaking and shortening.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If an adjustable suspension of the decorative panel is provided, then the position can be aligned with adjacent furniture fronts, but the opening of the decorative panel cannot be exactly aligned with the dispensing opening

Engineering Contradiction:
Improveadjustability of decorative panel positionVSAvoidalignment precision of opening
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The frame part acts as an intermediary element between the decorative panel and the dispensing device. It includes a cover part covering the edges of the opening and an inner sleeve arranged between the cover part and the front face, providing a reference structure that facilitates precise alignment of the opening with the dispensing opening.

Inventive Principle:
Principle #24Intermediary (Mediator)
