Universal Door Handle With Rotatable Grip And Cam Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door handles are not universally compatible with European or recessed locks and Anglo-Saxon or American locks, and they are difficult to install on glass doors or as replacements for already installed handles.
Innovation Solution
A handle design featuring a rotatable grip with a connecting bar that can be adapted to both European and Anglo-Saxon locks, allowing for easy installation on glass doors and enabling multi-directional operation without replacing existing locks, using a mechanism that integrates a cam system to convert rotary motion into linear motion and control lock mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a handle is designed for European or recessed locks, then the handle can be easily replaced, but the lock has a cumbersome installation on the door and its assembling on glass doors is problematic
Solution Approach 1:
The handle is designed with a universal connecting bar that can interface with both European recessed locks and Anglo-Saxon locks, allowing a single handle design to serve multiple lock types. The connecting bar includes adaptation elements that enable compatibility with different lock mechanisms without requiring separate handle designs for each lock type.
2Adaptability or versatility
If a handle is designed for Anglo-Saxon locks, then the handle contains an integrated mechanism, but the handle can be replaced only by other handles which have the same internal mechanisms
Solution Approach 1:
The handle is divided into distinct functional modules: the grip portion, the connecting bar, and the internal mechanism. The connecting bar serves as an interface element that can be adapted to different lock types while the internal mechanism remains separate. This segmentation allows the handle to maintain integrated functionality for Anglo-Saxon locks while enabling replacement with handles having different mechanisms through the universal connecting bar interface.
Solution Approach 2:
The connecting bar is designed as a universal interface that can connect to both European recessed locks and Anglo-Saxon locks, allowing a single handle design to replace handles on different lock types. The connecting bar includes adaptation elements that enable compatibility with different lock mechanisms.
3Ease of operation
If a handle is designed with a connecting bar for European locks, then the handle controls the latch movement, but the lock has a cumbersome installation on the door
Solution Approach 1:
The connecting bar is designed as a universal interface that can connect to both European recessed locks and Anglo-Saxon locks, allowing a single handle design to serve multiple lock types. This universality simplifies door installation by eliminating the need to choose different handles based on lock type, while maintaining the latch control functionality through the adapting elements in the connecting bar.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The handle provides universal compatibility with different lock types, facilitates easy installation on glass doors, and allows for multi-directional operation, enabling the addition of a multidirectional opening mechanism to doors with existing recessed locks without replacing the lock.

AI summary
A handle (10) for universal assembly is described, comprising a grip (11) assembled on a hollow handle body (46) and rotatable around a first axis (X-X) of the handle body (46), a revolving element (35) associated with the grip (11) and assembled rotatable around the first axis (X-X), a connecting bar (45) connected to the revolving element (35) and adapted to connect the handle (10) to a lock, wherein the connecting bar (45) is hollow for passing therein a stem (71) for a direct connection between the two handles (10) of a door.
