Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing disc locks lack the capability to be locked and unlocked via near field communication (NFC).
Innovation Solution
A disc lock mechanism powered by NFC, comprising a lock ring, top and bottom housings forming a lock chamber with an integrated antenna system that receives NFC signals to activate a motor, which moves the lock mechanism between locked and unlocked positions, using a lock ball cam and lever system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional disc lock mechanism is used, then the structure is simple and easy to manufacture, but it lacks the capability to be locked and unlocked via near field communication (NFC)
Solution Approach 1:
The antenna system is integrated within the lock chamber housing, with the antenna chamber located inside spaces defined by the lock ring or protruding from the housing. This nesting approach allows NFC functionality to be incorporated without significantly increasing the overall device footprint or structural complexity.
Solution Approach 2:
The lock mechanism serves multiple functions: it provides traditional mechanical locking through the lock ball cam and lever system, while also enabling remote locking and unlocking via NFC communication through the integrated antenna system, making the device adaptable to both contactless and traditional operating modes.
2Adaptability or versatility
If an antenna system is integrated into the lock chamber, then NFC functionality is achieved, but the device complexity increases
Solution Approach 1:
The antenna system is positioned within the lock chamber housing structure, utilizing existing spaces either defined by the lock ring or protruding tangentially from the annular taurus shape. This integration minimizes additional structural requirements and keeps the antenna system compact within the existing device envelope.
Solution Approach 2:
The antenna system is merged with the lock chamber housing, combining the NFC communication function with the existing mechanical structure. The antenna chamber is formed as part of the housing rather than as a separate external component, reducing overall device complexity.
3Area of stationary object
If the antenna chamber is located inside the spaces defined by the lock ring or protruding from the housing, then space utilization is optimized, but manufacturing precision requirements increase
Solution Approach 1:
The antenna chamber is positioned asymmetrically within the annular taurus shaped lock chamber, utilizing spaces that protrude tangentially from the lock ring or extend from the top or bottom of the housing. This asymmetric placement optimizes space utilization while accommodating the antenna system within the existing housing geometry.

AI summary
Described herein is a Near Field Communication disc lock. The disc lock has a near field communication antenna which receives the near field signal to lock or unlock the disc lock. The antenna passes the signal via wires to a near field circuit board which controls the lock motor which turns a lock cam to pressure or release a lock ball. The lock ball triggers the lock ball lever to lock or unlock the lock ring. In this manner, there is now an NFC lock which cannot be cut with bolt cutters.
