Transparent Adapter Optical Identification for Power Outlet Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power supply systems with multiple closely spaced electrical outlets face interference issues when using RFID tags for identifying power plugs, making it difficult to determine the correspondence between power plugs and outlets.
Innovation Solution
An identification adapter with a transparent resin case, a socket for the power plug, an adapter plug that can be inserted into another outlet, and an identification mark between the adapter plugs, along with reading sensors near each outlet in the power supply apparatus, which uses environment light to read the mark and specify the connected adapter plug, thereby avoiding interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RFID tags are used for identifying power plugs, then identification capability is improved, but interference occurs due to close proximity frequency band usage
Solution Approach 1:
The patent replaces the RFID electromagnetic identification system with an optical identification system. A transparent member with an identification mark is positioned in the adapter, and a reading sensor detects this mark through optical means, thereby avoiding the frequency interference inherent in RFID systems while maintaining identification capability.
Solution Approach 2:
The transparent member with identification mark serves as an intermediary between the adapter and the reading sensor. This intermediary enables identification without direct electromagnetic communication, thus eliminating frequency band interference while still allowing the system to distinguish between different adapters and outlets.
2Area of stationary object
If multiple electrical outlets are placed close together, then space utilization is improved, but identification of corresponding power plugs becomes difficult
Solution Approach 1:
Each adapter is equipped with a unique identification mark on its transparent member, and each outlet has a corresponding reading sensor positioned to detect that specific mark. This local differentiation allows the system to maintain accurate correspondence information between power plugs and outlets even when multiple outlets are placed close together in space.
3Difficulty of detecting and measuring
If a transparent resin case is used for the adapter, then optical reading is enabled, but manufacturing complexity increases
Solution Approach 1:
The patent changes the material parameter of the adapter case from opaque to transparent resin. This parameter change enables optical reading through the case while the identification mark is integrated into the transparent member, allowing for relatively straightforward manufacturing through molding processes.
