Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wire locks with plastic shells cannot meet the high-strength tensile requirements necessary for 'H' level classification, as they cannot embed an RFID chip due to signal shielding issues with metal shells.
Innovation Solution
A wire lock design that incorporates a plastic shell with an embedded RFID chip and a crossbeam made of high-strength material, such as metal or glass fiber, to enhance the tensile strength of the wire rope while allowing for RFID functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a metal shell is used to increase tensile strength, then the tensile strength reaches 'H' level, but the RFID chip cannot be embedded due to signal shielding
Solution Approach 1:
The shell is divided into two separate components: a plastic shell for embedding the RFID chip and a metal crossbeam for providing tensile strength. This segmentation allows each component to fulfill its specific function without interfering with the other, resolving the contradiction between RFID signal transmission and mechanical strength.
Solution Approach 2:
The plastic shell acts as an intermediary between the RFID chip and the external environment, providing a non-shielding enclosure that protects the chip while allowing RF signal transmission. The metal crossbeam serves as a structural intermediary that provides tensile strength without directly contacting the RFID chip, thus avoiding signal interference.
2Object-generated harmful factors
If a plastic shell is used to enable RFID chip embedding, then the RFID chip can be embedded, but the tensile strength cannot meet 'H' level requirements
Solution Approach 1:
The invention merges the plastic shell and metal crossbeam into a composite structure where the plastic shell provides RFID compatibility and the metal crossbeam provides tensile strength. The wire rope is connected to both the plastic shell and metal crossbeam, creating a hybrid system that combines the advantages of both materials to meet both RFID and strength requirements.
3Device complexity
If the wire rope is directly connected to the plastic shell, then the structure is simple, but the tensile strength is insufficient
Solution Approach 1:
The connection structure is designed asymmetrically with the metal crossbeam providing the primary load-bearing path for tensile forces, while the plastic shell provides secondary support and houses the RFID chip. The wire rope connects to the metal crossbeam at one end and the plastic shell at the other, creating an asymmetric load distribution that optimizes both strength and RFID functionality.

Function Achieved in This Case
The solution effectively increases the tensile strength of the wire lock to meet 'H' level requirements while maintaining the ability to embed an RFID chip, thus addressing the limitations of both plastic and metal shell designs.
Implementation Method 1
The basic working principle of RFID is that the reader/writer sends a radio frequency signal of a specific frequency through a transmitting antenna. When the electronic tag enters the working area where the RF signal is located, it will generate induced current, thereby obtaining energy and activating the electronic tag
Implementation Method 2
A wire lock design that incorporates a plastic shell with an embedded RFID chip and a crossbeam made of high-strength material, such as metal or glass fiber, to enhance the tensile strength of the wire rope
