Solution Overview

Problem

Existing cover solutions for refrigeration devices require tools for assembly and disassembly, are difficult to replace, and do not allow for a relief surface or easy adaptation to changing designs, particularly in the catering sector.

Innovation Solution

A set of cladding elements with form-fitting connections that attach to refrigeration devices without screws or other fastening elements, allowing for easy attachment and removal, and enabling a solid structure with optional decorative elements and ventilation for improved air circulation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If cladding elements are attached using screws or fastening elements, then the connection strength and stability are improved, but the assembly and disassembly time increases and tools are required

Engineering Contradiction:

Improveconnection strengthVSAvoidassembly and disassembly time

Core Design Contradiction:

StrengthVSLoss of time

Solution Approach 1:

The patent replaces the traditional mechanical fastening system (screws, bolts, clips) with a form-fitting connection system. The cladding elements feature geometric shapes and complementary profiles that interlock through friction and geometric constraint, eliminating the need for separate fastening elements while enabling tool-free assembly and disassembly.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The cladding elements are designed with self-aligning and self-latching features through their form-fitting connections. The geometric profiles automatically guide the elements into proper alignment and secure themselves through friction and interlocking shapes during assembly, without requiring external tools or additional fastening operations.

Inventive Principle:

Principle #25Self-service

2Ease of manufacture

If adhesive films are used for decoration, then the optical effect is achieved in a simple manner, but the removal or replacement becomes difficult

Engineering Contradiction:

Improvesimplicity of applicationVSAvoidremoval and replacement ease

Core Design Contradiction:

Ease of manufactureVSEase of repair

Solution Approach 1:

The patent divides the cladding system into separate, modular elements that can be independently applied and removed. Each cladding element is a discrete component with form-fitting connections, allowing individual elements to be replaced without affecting the entire covering system, unlike adhesive films that require complete removal.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces the adhesive bonding mechanism with a mechanical form-fitting connection system. This substitution allows cladding elements to be attached and detached through geometric interlocking and friction, enabling easy replacement without the permanent bonding characteristics of adhesive films.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Stability of the object's composition

If traditional cladding systems are used, then the device structure is stable, but the ability to change appearance frequently is limited due to wear and complex assembly

Engineering Contradiction:

Improvestructural stabilityVSAvoidability to change appearance

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent segments the cladding system into modular, interchangeable elements that can be easily swapped. Each element maintains structural integrity through form-fitting connections while allowing frequent replacement to change the device appearance, combining stability with adaptability.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a dynamic cladding system where elements can be easily attached and detached. The form-fitting connections provide stable attachment during use but allow controlled disassembly when appearance changes are desired, enabling the system to transition between stable and adaptable states.

Inventive Principle:

Principle #15Dynamics

4Shape

If cladding elements are made to fit tightly, then a solid appearance is achieved, but air circulation is restricted

Engineering Contradiction:

Improvesolid appearanceVSAvoidair circulation restriction

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent applies different qualities to different parts of the cladding elements. The outer surfaces are designed with smooth, continuous profiles for solid appearance, while specific localized areas incorporate ventilation openings and gaps that allow air circulation without compromising the overall aesthetic quality.

Inventive Principle:

Principle #3Local quality
