Lightweight Plastic Wall Panel with Direct Decorative Layer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall and ceiling panels are heavy, making them difficult to handle and transport, and they often require complex structures with wood fiberboards that add weight and cost.
Innovation Solution
A lightweight wall or ceiling panel design featuring a plastic rear wall without wood fibers, where a decorative layer is directly applied to the rear wall, potentially using recycled plastics fibers and various materials like veneer, stone, or metal for aesthetic and functional benefits, and incorporating sound-absorbing structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If wood fiberboard is used as the rear wall or mounting layer, then the panel has good structural stability and surface flatness, but the weight increases significantly
Solution Approach 1:
The patent removes the wood fiberboard layer entirely from the panel structure. Instead of using traditional MDF or particle board as the rear wall or mounting layer, the invention uses only the necessary components (decorative layer directly on support structure), extracting the excessive weight-causing element while maintaining structural integrity through alternative design
Solution Approach 2:
The patent changes the material parameter from heavy wood fiberboard to lighter alternatives, and adjusts the structural configuration parameter by eliminating intermediate layers. This parameter change directly reduces weight while the design maintains stability through proper attachment mechanisms and structural support
2Strength
If multiple layers including wood fiberboard are used, then the panel achieves sufficient strength and durability, but the handling and transport difficulty increases
Solution Approach 1:
By removing the heavy wood fiberboard layer, the patent extracts the source of handling difficulty while preserving essential strength functions through the remaining structural components, making the panel easier to carry, install, and maneuver during construction
Solution Approach 2:
The patent employs composite material construction combining the decorative layer with the support structure in a integrated design, creating a lightweight yet strong composite panel that maintains durability while improving ease of operation during installation and transport
3Reliability
If traditional multi-layer construction with wood fiberboard is used, then the panel has adequate functionality, but the production complexity and cost increase
Solution Approach 1:
The patent extracts the unnecessary wood fiberboard intermediate layer from the traditional multi-layer construction, simplifying the production process by reducing the number of materials to source, store, and assemble, while maintaining all essential panel functions through the streamlined design
Solution Approach 2:
The patent merges the functions of the decorative layer and support structure into a more integrated configuration, eliminating the need for separate wood fiberboard mounting layers. This merging reduces production complexity by decreasing the number of distinct components and assembly steps required
Data Source
AI summary
A wall panel or a ceiling panel includes a rear wall which is made of a plastic, and a decorative layer which is arranged directly on the rear wall.
