Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current high impact polystyrene (HIPS) composite panels used in refrigerators and freezers suffer from low strength, fragility, and poor corrosion resistance, leading to cracking issues and quality problems.
Innovation Solution
A HIPS material composition comprising 45-55 parts by weight of HIPS, 15-25 parts by weight of rubber, 10-15 parts by weight of polyethylene, 1-10 parts by weight of naphthenic oil, and 1-10 parts by weight of additives, specifically selected for improved glossiness and corrosion resistance, is used to form a composite panel that is co-extruded and thermoformed for use in refrigeration devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If common high light polystyrene (HIPS) is used for the panel layer, then glossiness is improved, but strength and corrosion resistance deteriorate
Solution Approach 1:
The patent applies composite materials by combining HIPS with rubber (15-25 parts by weight) and polyethylene (10-15 parts by weight) to create a multi-component composition. This composite approach allows the material to simultaneously achieve high glossiness from the HIPS component while gaining improved strength and corrosion resistance from the rubber and polyethylene components, directly resolving the contradiction between glossiness and mechanical properties.
Solution Approach 2:
The patent applies parameter changes by optimizing the specific ratios of HIPS, rubber, and polyethylene within defined ranges. By carefully controlling these compositional parameters, the material achieves the optimal balance between glossiness and mechanical strength, transforming the trade-off into a controllable parameter optimization problem.
2Illumination intensity
If common high light polystyrene is used for the panel layer, then glossiness is improved, but fragility increases
Solution Approach 1:
The patent uses composite materials to combine HIPS with rubber and polyethylene, where the rubber component specifically addresses fragility by providing flexibility and impact resistance. This composite structure maintains the high glossiness of HIPS while eliminating the fragility problem through the toughening effect of rubber.
Solution Approach 2:
The patent optimizes the rubber content parameter (15-25 parts by weight) to achieve the right balance between reducing fragility and maintaining glossiness. This parameter optimization allows the material to transition from fragile to reliably durable while preserving aesthetic appearance.
3Illumination intensity
If common high light polystyrene is used for the panel layer, then glossiness is improved, but cracking resistance deteriorates
Solution Approach 1:
The patent applies composite materials where rubber and polyethylene components work together with HIPS to prevent cracking. The rubber provides elasticity and stress distribution, while polyethylene enhances overall durability, creating a composite that resists cracking while maintaining the high glossiness characteristic of HIPS.
Solution Approach 2:
The patent optimizes the compositional parameters of the composite, specifically the ratios of HIPS, rubber, and polyethylene, to achieve optimal cracking resistance. By controlling these parameters within specified ranges, the material achieves both aesthetic glossiness and structural integrity against cracking.
