Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frame parts for doors, windows, or panels often rely on metal reinforcing cores, which are not recyclable and lack insulating properties, posing sustainability and efficiency challenges.
Innovation Solution
Replace metal reinforcing cores with bio composite materials, comprising biological materials embedded in plastic, offering improved stiffness, strength, and insulation while being recyclable.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If metal reinforcing cores are used, then strength and stiffness are provided, but recyclability is poor and insulating properties are lacking
Solution Approach 1:
The patent applies composite materials by combining biological materials (such as plant fibers, wood flour, or other natural fillers) with thermoplastic polymers to create a bio composite reinforcing core. This composite structure provides both mechanical strength from the polymer matrix and insulating properties along with recyclability from the biological components, thereby resolving the contradiction between strength and harmful factors.
Solution Approach 2:
The patent changes the material parameters by replacing metal with bio composite materials, altering the physical and chemical properties of the reinforcing core. This parameter change enables the core to possess both structural integrity (through optimized fiber content, particle size, and distribution) and improved environmental properties (recyclability and thermal insulation), thus resolving the technical contradiction.
2Object-generated harmful factors
If bio composite materials are used, then recyclability and insulating properties are improved, but structural strength may be insufficient
Solution Approach 1:
The patent uses composite materials with optimized composition, where biological fillers (such as cellulose fibers, wood flour, or plant-based particles) are dispersed within a thermoplastic matrix. The composite structure leverages the reinforcement effect of biological materials while maintaining the ductility and strength of the polymer, achieving both improved environmental properties and sufficient structural strength.
Solution Approach 2:
The patent applies local quality by optimizing the distribution, orientation, and concentration of biological materials within the reinforcing core. By controlling the local composition (e.g., higher fiber concentration in load-bearing regions, optimized particle size distribution), the bio composite core achieves uniform strength characteristics while maintaining recyclability and insulating properties throughout the structure.
3Ease of manufacture
If plastic hollow profiles are used, then ease of manufacture and insulating properties are improved, but stiffness and strength are insufficient
Solution Approach 1:
The patent applies composite materials by incorporating biological fillers (such as plant fibers, wood flour, or natural particles) into the thermoplastic polymer matrix of the hollow profile. This composite structure enhances the stiffness and strength of the plastic profile while maintaining the ease of manufacture through conventional extrusion and molding processes, thereby resolving the contradiction between ease of manufacture and mechanical properties.
Solution Approach 2:
The patent applies universality by designing a multi-functional bio composite hollow profile that simultaneously provides structural strength, thermal insulation, and ease of manufacturing. The bio composite material serves multiple functions: reinforcement from biological fillers, flexibility and processability from the thermoplastic matrix, and insulating properties from the composite structure, making the profile universally applicable while resolving the technical contradiction.
