Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cladding materials for building structures, such as wood, concrete, and steel, face issues like high cost, maintenance, vulnerability to graffiti, and difficulty in maintaining an aesthetically pleasing appearance due to pollution accumulation and limited sound attenuation capabilities.
Innovation Solution
The development of rotationally moulded plastic cladding panels with asymmetric surface variations and integrated mounting formations, which are lightweight, easy to transport, and feature a hollow shell structure made from polyolefin materials, providing a durable and aesthetically appealing solution for cladding that can be easily mounted and maintained.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If steel panels are used for cladding, then strength and durability are improved, but weight and cost increase significantly
Solution Approach 1:
The patent employs a hollow plastic panel with a thin-walled structure that provides sufficient strength through its geometric configuration rather than material mass. The panel walls are formed to varying thicknesses in different regions to optimize strength-to-weight ratio, eliminating the need for heavy solid materials while maintaining structural integrity.
Solution Approach 2:
The patent uses plastic material (such as polyethylene or polypropylene) to create a composite hollow structure that combines the benefits of light weight with adequate strength. The hollow configuration acts as a structural composite, providing rigidity and strength without the weight penalty of solid steel panels.
2Duration of action of stationary object
If concrete panels are used for cladding, then durability is improved, but weight increases and cracking/chipping resistance deteriorates
Solution Approach 1:
The hollow plastic panel structure provides flexibility and impact resistance that prevents cracking and chipping. The plastic material can absorb impacts without fracturing like concrete, while the hollow configuration adds structural rigidity to prevent deformation over time, achieving durability without brittleness.
3Shape
If wood panels are used for cladding, then aesthetic appearance is improved, but maintenance requirements increase due to deterioration and burning risks
Solution Approach 1:
The patent modifies the physical and chemical parameters of the panel material by using treated plastic that can be molded into wood-like aesthetic appearances. The plastic material inherently resists deterioration and burning, eliminating maintenance issues associated with wood while preserving the desired aesthetic qualities through surface texturing and coloring.
4Strength
If conventional cladding materials are used, then structural integrity is maintained, but resistance to graffiti and pollution accumulation deteriorates
Solution Approach 1:
The patent changes the surface parameters of the panel by using smooth, non-porous plastic material that resists graffiti adhesion and pollution accumulation. The surface properties are engineered to be easily cleanable while the hollow structural configuration maintains structural integrity, creating a panel that is both strong and resistant to environmental degradation.

AI summary
Some embodiments relate to a moulded cladding panel. The panel may comprise: a hollow plastic body formed by rotational moulding, the body having a length, a width and a depth, a first end, an opposite second end, an upper section, an opposite lower section, a first major face defined by a front wall extending from the first end to the second end and from the upper section to the lower section, and a second major face defined by a back wall opposite the first major face, the second major face extending from the first end to the second end and from the upper section to the lower section. The upper section defines a plurality of first mounting formations to facilitate mounting of the panel to a structure to be clad. The lower section defines a plurality of second mounting formations to facilitate mounting the panel to the structure.
