Cross Bar Unlock-Driving Structure for Universal Lock Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lock structures require specific unlock-driving structures for different types of locks, leading to high manufacturing costs and complex replacement processes.
Innovation Solution
A cross bar type unlock-driving structure that can be mounted in a panel-outside space of a door panel, capable of applying to various lock types, including single-point, double-point, three-point, vertical single-point, embedded lock cartridges, and embedded vertical double-point lock-driving structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different unlock-driving structures are used for different lock types, then each lock can be properly controlled, but manufacturing cost increases and replacement becomes tedious
Solution Approach 1:
The patent applies universality by designing a single unified unlock-driving structure that can control multiple types of locks (single-point lock, double-point lock, three-point lock, embedded lock cartridges). The structure includes a handle assembly, drive transmission mechanism, and mounting base that can accommodate different lock configurations through standardized interfaces and adjustable mounting positions, eliminating the need for separate unlock-driving structures for each lock type.
Solution Approach 2:
The patent applies segmentation by dividing the unlock-driving structure into modular components: a handle assembly, a drive transmission mechanism, and a mounting base. This modular design allows the same basic structure to be adapted to different lock types by reconfiguring or repositioning components rather than requiring entirely different structures for each lock type.
2Reliability
If multiple specialized unlock-driving structures are manufactured, then each lock type has dedicated control, but manufacturing cost becomes expensive
Solution Approach 1:
The unified unlock-driving structure reduces manufacturing costs by producing a single standardized design rather than multiple specialized structures. The structure maintains reliable lock control through its universal drive transmission mechanism that can interface with different lock types using standardized mounting interfaces and adjustable components.
Solution Approach 2:
The patent merges the functionality of multiple specialized unlock-driving structures into a single unified design. By combining the handle assembly, drive transmission, and mounting base into one standardized unit that can serve multiple lock types, the manufacturing process is simplified and costs are reduced while maintaining reliable control functionality.
3Ease of operation
If different unlock-driving structures are used for different locks, then proper functionality is achieved, but replacement and maintenance become extremely tedious
Solution Approach 1:
The unified unlock-driving structure simplifies replacement and maintenance by providing a standardized design that can control multiple lock types. When replacement is needed, the same universal structure can be reused across different lock installations rather than requiring specialized structures for each lock type, making the replacement process less tedious.
Solution Approach 2:
The modular segmented design of the unlock-driving structure (handle assembly, drive transmission, mounting base) allows for easier maintenance and replacement. Components can be individually serviced or replaced without affecting the entire system, and the standardized interfaces enable quick swapping between different installations.

AI summary
A cross bar type unlock-driving structure, to be mounted in a panel-outside space of a door panel, includes a handle-end frame, a mounting frame, a handle and a driving member, and a handle seat. The handle-end base includes a basic frame and a mounting frame to form an accommodation space with both vertical and horizontal opening. The handle and the driving member, integrated as a unique piece, provide the driving member to be formed as an extension finger for pushing an unlock-driven unit disposed inside the accommodation space. The handle seat, mounted onto the middle plate of the mounting frame, is to mount pivotally the handle and the driving member with the driving member located in the accommodation space and the handle located out of the handle seat. With the vertical and horizontal opening provided to the accommodation space, different types of lock cartridges can be contained.
