Tensioning Device Locking Means Below Horizontal Plane
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tensioning devices often result in abrupt belt relaxation and uncontrolled unloading of lashed goods due to limited control over the release mechanism, leading to increased wear and tear and suboptimal operation.
Innovation Solution
The tensioning device features a locking means arranged below the horizontal plane of the tensioning frame, allowing for a significant arc angle of the control cam and sliding edge to smoothly transition the locking means out of engagement with the ratchet wheel, enabling a larger pivoting range and reduced wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the locking means is arranged above or at the horizontal plane of the tensioning frame, then the structure is simpler and easier to manufacture, but the control cam can only work over a small rotational path causing abrupt belt relaxation and uncontrolled unloading
Solution Approach 1:
The locking means is repositioned from a vertical arrangement (above or at the horizontal plane) to a horizontal arrangement (below the horizontal plane), changing the spatial dimension of the mechanism. This dimensional shift allows the control cam to operate over a larger rotational path (at least 10 degrees) while maintaining structural integrity, thereby enabling controlled belt release without increasing overall device complexity
2Ease of operation
If the control cam works over a small rotational path, then the device structure is simpler, but the belt releases abruptly causing uncontrolled unloading of lashed goods
Solution Approach 1:
The rotational path parameter of the control cam is increased from a small angle to at least 10 degrees by repositioning the locking means below the horizontal plane. This parameter change transforms the release mechanism from abrupt to controlled, allowing gradual belt relaxation while maintaining device simplicity through the geometric reconfiguration rather than adding complex control systems
3Reliability
If the clamping lever has a limited pivoting range, then the device is more compact, but wear and tear increases due to repeated engagement and disengagement
Solution Approach 1:
By positioning the locking means below the horizontal plane defined by the connection and guide elements, the clamping lever gains an extended pivoting range that allows smoother transition between engagement and disengagement states. This spatial reconfiguration reduces mechanical stress and wear on the ratchet teeth and locking means, improving reliability without requiring additional protective mechanisms
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
This design allows for controlled belt release under maximum load, minimizing wear and enhancing operational efficiency by increasing the pivoting range of the clamping lever and enabling higher pretensioning forces.
Implementation Method 1
there is also a control cam, with the help of which the locking means associated with the ratchet wheel is transferred into an inoperative position
Implementation Method 2
at least one associated ratchet wheel, and with a locking means interacting with the ratchet wheel
Implementation Method 3
a driver element which interacts with the ratchet wheel is usually mounted on the tensioning lever so that it can be displaced against the action of a restoring element

AI summary
The device has a tensioning frame comprising a connection element (3) and a tensioning lever (7) supported in a pivotable manner. The lever operates a drive shaft (5) that is rotatably supported around an axis. The drive shaft has a locking gear wheel (9) and a locking unit (10) is arranged at an end of the frame. The locking unit is arranged below a horizontal plane of the frame, where the plane is defined by the connection element and a guiding element (4). The connection and guiding elements are designed as connection bolts for coupling side walls (2) of the frame with each other.
