Solution Overview

Problem

Existing home appliance devices face inefficiencies in assembly and disassembly, cooling performance, and design, particularly in the connection and stability of panels covering machine compartments, which hinders improved functionality and versatility.

Innovation Solution

The implementation of a connection unit with elongate elements and fin mounting elements that allow for toolless assembly and disassembly, improved air redirection, and enhanced stability through reinforcement profiles and guiding elements, enabling efficient connection of panel modules and improved design flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional connection methods are used for panels, then assembly requires tools and time, but the connection unit enables toolless assembly and disassembly

Engineering Contradiction:
Improveassembly easeVSAvoidassembly time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The panel connection system is segmented into modular components: panel modules with connection elements, fin mounting elements, and interlocking features. This segmentation allows individual modules to be assembled and disassembled independently using the connection unit, enabling toolless assembly while maintaining structural integrity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connection unit acts as an intermediary mechanism between panel modules and fin mounting elements. It includes guiding elements that align components and interlocking features that secure them together without requiring external tools, thus facilitating easy assembly and disassembly.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Stability of the object's composition

If panels are made stable and secure, then design flexibility is reduced, but the connection unit allows mirror-inversion and reconfiguration

Engineering Contradiction:
Improvepanel stabilityVSAvoiddesign flexibility
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connection unit incorporates dynamic features such as movable guiding elements and reversible interlocking mechanisms. These allow panel modules to be reconfigured, mirrored, or inverted while maintaining stable connections during operation, thus providing both stability and design flexibility.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connection unit is designed with universal features that allow the same panel modules to be used in multiple configurations and orientations. The guiding elements and interlocking mechanisms work regardless of the panel's orientation, enabling mirror-inversion and reconfiguration while maintaining structural stability.

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

3Ease of manufacture

If connection elements are exposed for assembly, then assembly is simple, but aesthetics are compromised, but the connection unit covers screws efficiently

Engineering Contradiction:
Improveassembly simplicityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The connection unit merges the functional connection elements (screws, fasteners) with aesthetic panel components. The fin mounting elements and panel modules are designed to visually integrate the connection hardware, so that assembly simplicity is maintained while the aesthetic appearance is preserved through integrated design.

Inventive Principle:
Principle #5Merging (Combining)
