Solution Overview
Problem
There is a need for a convenient system that can assess both the physical and functional condition of wireless communication devices, such as mobile phones and tablets, to facilitate their recycling and re-use, while ensuring environmental sustainability by preventing electromagnetic interference.
Innovation Solution
A system comprising an assessment area and an enclosure that is impenetrable to electromagnetic radiation, which illuminates the device, captures images, and communicates with it to extract information, using LED arrays, cameras, and antennas to assess physical condition and functionality, and a motorized transfer mechanism to move the device between areas for complete evaluation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device is assessed in an open environment, then communication with the device is easier, but electromagnetic interference may affect the assessment accuracy and security
Solution Approach 1:
The assessment system is divided into two distinct functional zones: an assessment area for physical inspection and an enclosure for functional testing. This segmentation allows each zone to be optimized for its specific purpose while isolating electromagnetic-sensitive operations from external interference.
Solution Approach 2:
The harmful electromagnetic environment is extracted from the assessment process by placing communication-sensitive functional tests inside an electromagnetic enclosure, separating them from the open assessment area where physical inspection occurs.
2Object-affected harmful factors
If the enclosure is made completely impenetrable to electromagnetic radiation, then electromagnetic isolation is improved, but communication with the device becomes more difficult
Solution Approach 1:
An electromagnetic enclosure acts as an intermediary environment that provides isolation from external electromagnetic interference while still allowing controlled communication with the device through its walls, enabling both protection and interaction.
3Object-affected harmful factors
If the assessment area and enclosure are separate, then electromagnetic isolation is maintained, but the transfer mechanism adds system complexity
Solution Approach 1:
The transfer mechanism uses a motorized belt and pulley system to automatically move the receptacle between the assessment area and enclosure, replacing manual handling and reducing the need for complex mechanical interfaces while maintaining electromagnetic isolation.
4Measurement precision
If multiple LED arrays and cameras are used for comprehensive assessment, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The LED arrays and cameras are integrated into a multi-functional assessment system that performs both physical condition evaluation and functional testing, allowing a single complex subsystem to serve multiple assessment purposes rather than requiring separate dedicated systems.
