Solution Overview

Problem

Refrigeration devices with built-in dispensing devices for ice or water face challenges in aligning decorative panels with adjacent furniture, as the panels must not block access to the dispensing device, and existing solutions either compromise aesthetics or lead to poor space utilization.

Innovation Solution

An adjustable sleeve system is integrated into the niche, allowing the decorative panel to be adjusted while maintaining access to the dispensing device, using screws that penetrate elongated holes and engage in a thread within the niche, with a wedge mechanism for stability and adjustability, and a frame to fill gaps for a seamless appearance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If a decorative panel is installed on the door to achieve a built-in appearance, then the aesthetic appearance is improved, but the dispensing device becomes inaccessible or misaligned

Engineering Contradiction:
Improveaesthetic appearanceVSAvoidaccess to dispensing device
Core Design Contradiction:
ShapeVSEase of operation

Solution Approach 1:

The door front is segmented into a decorative panel and a separate sleeve structure. The sleeve is divided into an outer sleeve and an inner sleeve that can move independently, allowing the dispensing device to access through the decorative panel while maintaining its aesthetic appearance.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sleeve acts as an intermediary element between the decorative panel and the dispensing device. It provides a functional opening for the dispensing device while maintaining the aesthetic appearance of the decorative panel, and its movable nature allows it to mediate between the static panel and the operational device.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If a window is cut into the decorative panel for access to the dispensing device, then accessibility is improved, but the visual appeal is reduced due to misalignment during adjustment

Engineering Contradiction:
Improveaccess to dispensing deviceVSAvoidvisual appeal
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The sleeve is designed with movable parts including an inner sleeve that can shift position. This dynamic structure allows the opening to maintain alignment with the dispensing device regardless of the decorative panel's position, ensuring both accessibility and visual appeal during adjustment.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The position parameters of the sleeve and its opening can be adjusted to match the decorative panel's position. The elongated holes in the screws allow for positional parameter changes, enabling the opening to realign with the dispensing device when the panel is adjusted.

Inventive Principle:
Principle #35Parameter changes

3Ease of operation

If the dispensing device is placed in an area not covered by the decorative panel, then accessibility is maintained, but the built-in appearance is compromised and space utilization is poor

Engineering Contradiction:
Improveaccess to dispensing deviceVSAvoidbuilt-in appearance
Core Design Contradiction:
Ease of operationVSShape

Solution Approach 1:

The sleeve is nested within the decorative panel area, with the outer sleeve fitting into a recess and the inner sleeve containing the dispensing device. This nesting arrangement allows the dispensing device to be accessible while remaining within the decorative panel's footprint, maintaining the built-in appearance and efficient space utilization.

Inventive Principle:
Principle #7Nested doll (Nesting)

4Adaptability or versatility

If the decorative panel is made adjustable for alignment with adjacent furniture, then adaptability is improved, but the alignment with the dispensing device becomes inconsistent

Engineering Contradiction:
Improvealignment with furnitureVSAvoidalignment with dispensing device
Core Design Contradiction:
Adaptability or versatilityVSManufacturing precision

Solution Approach 1:

The sleeve's inner sleeve can move dynamically to compensate for positional changes in the decorative panel. This allows the panel to be adjusted for furniture alignment while the inner sleeve adjusts accordingly to maintain precise alignment with the dispensing device.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The positional parameters of the sleeve can be changed to match the decorative panel's adjusted position. The screws with elongated holes enable parameter changes in the sleeve's position, ensuring continued alignment with the dispensing device regardless of the panel's adjustment for furniture compatibility.

Inventive Principle:
Principle #35Parameter changes

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
