Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The environmental pollution caused by massive production of plastic products has led to a need for sustainable reuse of plastic materials, and existing technologies have not effectively addressed the challenge of creating durable and crack-resistant sheet structures from recycled plastics.
Innovation Solution
A sheet structure composed of recycled granule portions with surface layers, where the granules are fused together using a process that includes recycling, sieving, and heat pressing, resulting in a material with no cracks under ISO 5402-1 testing up to 10,000 cycles and an ultimate elongation of at least 200% as per ASTM D412 standards.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If recycled plastic granules are used to create sheet structures, then environmental sustainability is improved, but the structural integrity and crack resistance deteriorate
Solution Approach 1:
The patent uses composite materials by combining recycled plastic granules with binding agents to form a sheet structure. The granules are suspended in a binding agent and then cured to create a composite material that maintains structural integrity while using recycled content. This resolves the contradiction by creating a material that is both environmentally sustainable and structurally sound.
Solution Approach 2:
The patent applies parameter changes by controlling the curing process of the binding agent and adjusting the composition ratios of granules to binder. By optimizing these parameters, the sheet structure achieves adequate strength and crack resistance while maintaining high recycled content, thus resolving the contradiction between reliability and environmental sustainability.
2Duration of action of stationary object
If recycled plastic materials are processed into sheet structures, then material reuse is improved, but the durability and longevity worsen
Solution Approach 1:
The patent implements discarding and recovering by collecting discarded plastic materials, processing them into granules, and incorporating them into new sheet structures. This circular approach ensures that plastic waste is recovered and reused, extending the material's lifecycle and improving longevity while reducing plastic waste.
Solution Approach 2:
By creating composite materials with recycled granules and binding agents, the patent enhances the durability of the final product. The composite structure provides improved mechanical properties and resistance to degradation, ensuring the sheet structure has adequate longevity for practical applications while maintaining high material reuse rates.
3Ease of manufacture
If transparent or translucent panel portions are added to display recycled granules, then aesthetic appeal is improved, but manufacturing complexity increases
Solution Approach 1:
The patent merges the display function with the structural panels by incorporating transparent or translucent portions directly into the sheet structure. This integration allows the recycled granules to be visible while maintaining the panel's structural integrity, avoiding the need for separate display components and reducing overall manufacturing complexity.
Solution Approach 2:
The patent applies local quality by making only specific portions of the panel transparent or translucent where aesthetic display is desired, rather than making the entire structure transparent. This selective approach balances aesthetic appeal with manufacturing simplicity, as only localized areas require special material properties while the rest of the structure can be manufactured using standard processes.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a durable and sustainable sheet structure that is visible through a transparent or translucent panel, effectively utilizing recycled materials while maintaining structural integrity and aesthetic appeal.
Implementation Method 1
The first surface layer of one of the plurality of first recycled granule portions is fusingly connected to the first surface layer of another one of the plurality of first recycled granule portions and/or the second surface layer of one of the plurality of second recycled granule portions

AI summary
A sheet structure is provided and includes first recycled granule portions, second recycled granule portions, an upper surface, a lower surface and a first panel portion. Any two surface layers of the first recycled granule portions and the second recycled granule portions are fusingly connected each other. The first panel portion is disposed on the upper surface. A material of the first panel portion is a transparent material or a translucent material, so that the first recycled granule portions and the second recycled granule portions are visible through the first panel portion. The sheet structure has no crack under a test complaint with ISO 5402-1 up to 10,000 cycles, and an ultimate elongation of the sheet structure under a test compliant with ASTM D412 is equal to or greater than 200%.
