Biodegradable Electronic Housing for Component Separation and Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent replacement of external electronic devices with enhanced functionalities leads to environmental issues due to difficulties in recycling, as they are often disposed of in landfills.
Innovation Solution
An electronic device assembly with a biodegradable housing structure, comprising a biodegradable chassis and cover, which can house components like a printed circuit board and antennas, using materials such as cellulose acetate and PHA, allowing for biodegradation and subsequent component separation for recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plastic housing is used in electronic devices, then device durability and structural integrity are maintained, but recycling difficulty and environmental pollution increase
Solution Approach 1:
The patent changes the material parameter of the housing from traditional plastic to biodegradable material, transforming the environmental properties while maintaining structural functionality. This allows the housing to degrade naturally after use, eliminating the persistence problem of traditional plastics.
Solution Approach 2:
The patent employs composite material construction where the biodegradable housing integrates multiple functional layers including barrier layers, structural layers, and decorative layers, achieving both durability and biodegradability through material composition rather than single-material limitations.
2Object-generated harmful factors
If biodegradable materials are used for housing, then environmental friendliness and waste reduction are improved, but material strength and structural integrity may deteriorate
Solution Approach 1:
The biodegradable housing is constructed as a composite structure with multiple layers serving different functions: barrier layers for protection, structural layers for strength, and decorative layers for appearance. This composite approach allows each layer to be optimized for its specific function while maintaining overall structural integrity.
Solution Approach 2:
Different regions of the housing structure use biodegradable materials with locally optimized properties - some areas have enhanced barrier properties, others have reinforced structural characteristics, and decorative surfaces provide aesthetic functions. This local quality differentiation allows the housing to meet diverse performance requirements.
3Ease of manufacture
If biodegradable housing structure is used, then ease of recycling is improved through selective component removal, but device complexity increases due to integrated fastening mechanisms
Solution Approach 1:
The patent merges the housing structure with integrated fastening mechanisms, combining what would traditionally be separate components (housing and fasteners) into a unified biodegradable structure. This integration simplifies the overall device architecture while maintaining ease of component separation for recycling purposes.
Solution Approach 2:
The biodegradable housing is designed with segmented functionality where different components (cover, chassis, fastening members) can be selectively separated and removed. This segmentation allows individual components to be extracted for recycling while the biodegradable portions can be composted, facilitating multi-stream recycling processes.
