Modular Latch Control Device with Pivotable Locking Cap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing latch control devices are not adaptable to different types of latch devices and require mechanical replacement to incorporate electric lock functions, limiting their versatility and convenience.
Innovation Solution
A modular latch control device with a mounting seat, pivotable locking cap, detecting device, and adjustable fixing screws, allowing for assembly into multiple modes to cooperate with various latch devices, including cylindrical and box type latches, without detaching from the door, and enabling electric control of locking and unlocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mechanical latch device is used, then the door can be locked and unlocked mechanically, but the device cannot provide electric lock functions and must be replaced to incorporate electric control
Solution Approach 1:
The latch control device is designed with a universal mounting seat that can accommodate multiple types of latch devices (cylindrical latches, box type latches with single or dual latches) through adjustable fixing screws and a pivotable locking cap, enabling one device to control various latch configurations without requiring separate specialized controllers for each latch type
2Adaptability or versatility
If the latch control device is designed to accommodate multiple latch types, then versatility is improved, but the device structure becomes more complex
Solution Approach 1:
The fixing screws are designed to be adjustable in position along the mounting seat, allowing the device to adapt dynamically to different latch configurations. The locking cap can pivot between a closed position (when latch is engaged) and an open position (when latch is disengaged), providing dynamic control without requiring complex mechanical structures
3Ease of operation
If fixing screws with second driving holes are used, then rapid adjustment of component positions is enabled without detaching from the door, but the screw structure becomes more complex
Solution Approach 1:
The fixing screw is divided into distinct functional segments: a first driving hole in the head for initial positioning, a threaded shank for engagement with the mounting seat, and a second driving hole in the end face for final securing and adjustment. This segmentation allows different operations to be performed on different parts of the screw, enabling rapid adjustment without requiring the entire assembly to be detached

AI summary
A latch control device includes a mounting seat and a locking cap device pivotably mounted to the mounting seat and pivotable relative to the mounting seat between a closure position and a non-closure position. Optionally mounted to the latch control device are a first accessory, a second accessory, a third accessory, a first escutcheon, and a second escutcheon. The latch control device is selectively assembled into a first mode (including a detecting device), a second mode (including the detecting device, the first accessory, and the third accessory), or a third mode (including the detecting device, the first accessory, and the second accessory) for cooperating with a cylindrical latch device, a first box type latch device, or a second box type latch device.
