Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manufacturing information plates with embedded wireless identification devices, such as RFID transponders, is complicated by the need to integrate a sensitive electronic component with a sturdy, weatherproof structure, increasing costs and complicating the process.
Innovation Solution
A cavity is formed in the information plate body, into which a wireless identification device is placed, and connected via connecting pins to complete an electric circuit with the plate body, secured by a filler material, and attached to a flexible layer for durability and functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless identification device is embedded into the information plate, then the identification functionality is improved, but the manufacturing complexity and cost increase
Solution Approach 1:
The patent combines the wireless identification device with the information plate into a single integrated unit. The device is embedded within the plate structure, merging two separate components (plate and electronic device) into one unified product, thereby improving identification functionality while managing manufacturing complexity through integration
Solution Approach 2:
The wireless identification device is nested within the information plate structure. The device fits into a cavity or recess in the plate, with connecting pins extending through the plate body to establish electrical connections. This nesting approach allows the electronic component to be housed within the existing plate structure rather than adding a separate external component
2Reliability
If the information plate is made weatherproof to protect the embedded device, then the reliability is improved, but the manufacturing cost increases
Solution Approach 1:
The patent uses a flexible layer as a protective covering for the embedded wireless identification device. This thin film or flexible shell provides weatherproofing and environmental protection while maintaining a simple structure that does not significantly complicate the manufacturing process. The flexible layer can be applied over the embedded device to seal it from environmental factors
3Productivity
If the manufacturing process is simplified, then the productivity is improved, but the assembly reliability may worsen
Solution Approach 1:
The wireless identification device is pre-attached to a flexible layer before being mounted into the information plate. This preliminary assembly step allows the electronic component to be prepared and positioned on the flexible substrate in advance, simplifying the final insertion process into the plate cavity while ensuring proper alignment and connection pin positioning for reliable electrical contact

AI summary
An information plate body (10) has a cavity (11) or a slot for a wireless identification device (13). The wireless identification device (13) is attached to a flexible layer (12), a pre-processed layer carrying the wireless identification device (13) to the information plate body (10). The flexible layer (12) is placed on the information plate body (10), with the wireless identification device (13) being placed over the cavity (11). The wireless identification device (12) has at least two connecting pins (55) that extend to be in contact with the information plate body (10). The information plate body (10) is made of conductive material, such as metal. Placing the connecting pins (55) against the information plate body (10) completes the wireless identification device's (13) electric circuit. The information plate body is a functional part of a wireless identity transponder (12). One example of the wireless identity transponder is a RFID transponder.
