Intelligent Lockset Transmission Mechanism for Miniaturization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intelligent locksets in the market are larger due to their complex internal structures, which include multiple parts for mechanical and electrical unlocking modes, making them less convenient for transportation and installation.
Innovation Solution
The intelligent lockset design incorporates a transmission mechanism with a follower, transmission assembly, and knob shaft, allowing for both electric and mechanical locking/unlocking modes while minimizing space occupancy by aligning the follower and transmission assembly along the axis of the knob shaft.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the intelligent lockset includes more parts for mechanical and electrical unlocking modes, then the unlocking functionality is improved, but the size of the intelligent lockset increases
Solution Approach 1:
The patent combines the mechanical transmission components (follower, transmission assembly, knob shaft) into an integrated structure where the knob shaft penetrates both the follower and transmission assembly, allowing them to share common structural space. This merging of components enables dual unlocking modes while reducing the overall volume of the lockset.
Solution Approach 2:
The transmission assembly is disposed within the lock case, and the follower is rotatably disposed within the lock case with the transmission assembly. The knob shaft penetrates through multiple components (follower and transmission assembly), creating a nested arrangement where components are positioned within the spatial envelope of others, thereby minimizing the external dimensions while maintaining internal functionality.
2Adaptability or versatility
If the intelligent lockset includes more parts for mechanical and electrical unlocking modes, then the unlocking functionality is improved, but the ease of transportation and installation deteriorates
Solution Approach 1:
By merging the transmission components into a compact integrated structure where the knob shaft penetrates the follower and transmission assembly, the patent reduces the number of separate external parts that need to be handled during transportation and installation, while maintaining both mechanical and electrical unlocking capabilities.
Solution Approach 2:
The nested arrangement of components (transmission assembly within lock case, follower within lock case, transmission assembly penetrating follower via knob shaft) creates a compact unit that is easier to transport and install as a single integrated component rather than multiple separate parts.

AI summary
Disclosed are an intelligent lockset and a door. The intelligent lockset includes a first base, a lock body and a transmission mechanism. The lock body includes a lock case and a latch assembly, the lock case is connected to the first base, and the latch assembly is movably disposed in the lock case and is capable of extending or retracting relative to the lock case. The transmission mechanism includes a follower, a transmission assembly and a knob shaft, the follower is rotatably disposed in the lock case and is in transmission connection with the latch assembly, the transmission assembly is rotatably disposed on the first base, and the knob shaft is configured to penetrate the follower and the transmission assembly. The transmission assembly is capable of rotating under driving of a driving mechanism, and drives the follower to rotate through the knob shaft.
