Solution Overview

Problem

Existing wall and ceiling panels are heavy, making them difficult to handle and transport, and are costly to produce due to the use of traditional materials like wood fiber boards.

Innovation Solution

A wall or ceiling panel with a rear wall made of plastic fibers, where the decorative layer is directly applied to the rear wall, eliminating the need for a wood fiber layer, resulting in a lighter and more cost-effective solution.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a wood fiberboard layer (MDF) is used as the backing wall, then the panel has good structural stability and surface flatness, but the weight increases significantly

Engineering Contradiction:
Improvestructural stabilityVSAvoidpanel weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The invention extracts and removes the wood fiberboard layer from the panel structure, retaining only the essential functional layers. By eliminating the MDF backing wall and using a lightweight plastic foil instead, the solution achieves significant weight reduction while maintaining the necessary structural stability through the decorative layer and adhesive system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention changes the material parameter of the backing wall from dense wood fiberboard to lightweight plastic foil. This parameter change fundamentally alters the weight characteristic while maintaining the panel's structural integrity through appropriate adhesive bonding and layer configuration.

Inventive Principle:
Principle #35Parameter changes

2Strength

If traditional multi-layer construction with MDF is used, then the panel has sufficient strength and durability, but the manufacturing cost increases

Engineering Contradiction:
Improvepanel strengthVSAvoidmanufacturing cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The invention extracts the expensive wood fiberboard component from the traditional multi-layer construction and replaces it with a cost-effective plastic foil alternative. This removal of the MDF layer directly reduces material costs while maintaining panel strength through the adhesive-bonded decorative layer system.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention substitutes expensive, resource-intensive wood fiberboard with a cheaper plastic foil material. This replacement uses more economically viable materials to achieve the same structural function, thereby reducing overall manufacturing costs.

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

3Object-affected harmful factors

If a thick wood fiberboard layer is used, then the panel provides good sound absorption, but the weight and handling difficulty increase

Engineering Contradiction:
Improvesound absorptionVSAvoidhandling ease
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The invention changes the material parameters of the panel structure by replacing dense wood fiberboard with lightweight plastic foil. This parameter change reduces weight and improves handling ease while maintaining sound absorption capabilities through the decorative layer configuration and adhesive system.

Inventive Principle:
Principle #35Parameter changes
