Electronic Padlock Linear Blocker for NFC-Controlled Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic padlocks face challenges with rotating components and safety issues, necessitating a more sophisticated design.
Innovation Solution
An electronic padlock arrangement featuring a linearly movable blocker, a tilter, a clutch pin, and processing circuitry that controls the clutch pin to enable or disable the tilter's movement, utilizing Near Field Communication (NFC) for authorization and energy transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If rotating components are used inside the padlock, then the padlock can achieve locking and unlocking functionality, but safety issues and reliability problems occur
Solution Approach 1:
The patent replaces the traditional rotating mechanical components with a linearly movable blocker system. The blocker moves linearly between a first position (blocking the shackle) and a second position (allowing the shackle to open), eliminating the need for rotating parts and associated safety issues while maintaining the locking functionality.
2Reliability
If a controlled mechanism with clutch pin is implemented, then unauthorized tampering is prevented, but the device complexity increases
Solution Approach 1:
The patent divides the locking mechanism into distinct functional segments: the clutch pin (controlled by processing circuitry based on authorization), the tilter (which tilts to transfer motion), and the linearly movable blocker (which actually blocks or unblocks the shackle). This segmentation allows for controlled security while maintaining clarity in the mechanical pathways.
3Ease of operation
If NFC is used for authorization and energy transfer, then ease of operation is improved, but dependency on external technology increases
Solution Approach 1:
The patent uses NFC technology as an intermediary for contactless authorization and energy transfer. The NFC interface enables users to authenticate and power the padlock without physical contact, improving ease of operation while the processing circuitry manages the NFC communication internally.

AI summary
According to the invention, there is provided a padlock arrangement (100), comprising a body (102) with a shackle (104) and a linearly movable blocker (106) having a first position (106_P1) to disenable the shackle (104) to enter an open state (104_OS) and a second position (106_P2) to enable the shackle (104) to enter the open state (104_OS). The padlock arrangement further comprises a tilter (108) having a first position (108_P1) and a second position (108_P2), wherein moving of the tilter (108) from the first position (108_P1) to the second position (108_P2) is configured to move the blocker (106) from the first position (106_P1) to the second position (106_P2), and a clutch pin (110) having a first state (110_S1) to disable moving of the tilter (108) to the second position (108_P2), and a second state (110_S2) to enable moving of the tilter (108) to the second position (108_P2). The padlock arrangement further comprises a processing circuitry (112) configured, when authorized, to provide a control signal to set the clutch pin (110) to the second state (110_S2) to enable moving of the tilter (108) to the second position (108_P2) to open the shackle (104).
