Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing actuating devices for locking bolts lack the ability to transfer them abruptly into closed or released positions without relying on electrical components.
Innovation Solution
An actuating device with a drive element and an output element preloaded by an elastic element, where a locking device blocks movement until a trigger position is reached, allowing sudden movement upon release, achieved through mechanical means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking device blocks the output element throughout the entire movement range, then the output element remains securely fixed, but it cannot be moved abruptly when needed
Solution Approach 1:
The locking device transitions from a static blocking state to a dynamic releasing state based on the drive element's position. The locking element is movable along the displacement direction and can switch between blocking the output element and allowing its abrupt movement, enabling the system to adapt its constraint level according to operational needs.
Solution Approach 2:
The locking element acts as an intermediary between the drive element and the output element. It mediates the interaction by blocking the output element during most of the drive element's movement, then releasing it at the triggering position to enable abrupt movement, thus controlling the transfer of motion and force between the two components.
2Speed
If the output element is preloaded by an elastic element, then sudden movement can be achieved upon release, but the system requires a mechanism to control when release occurs
Solution Approach 1:
The elastic element is preloaded in advance during the initial positioning phase, storing potential energy while the locking element blocks the output element. This preliminary action allows the system to accumulate energy quietly, then release it suddenly when the drive element reaches the triggering position, achieving fast movement without complex control mechanisms.
Solution Approach 2:
The system uses the drive element's own movement to trigger the release automatically. When the drive element reaches the predetermined triggering position, it automatically causes the locking element to release the output element, eliminating the need for external control signals or additional actuation mechanisms.
3Ease of operation
If the locking device releases the output element at a specific trigger position, then abrupt movement is enabled, but the locking device must be precisely positioned along the drive element's path
Solution Approach 1:
The movement range of the drive element is segmented into distinct zones: a blocking zone where the locking element prevents output element movement, and a triggering zone where release occurs. This segmentation allows the locking device to be positioned at a specific triggering position without requiring extreme precision, as long as it falls within the defined triggering zone.
Solution Approach 2:
The locking device is positioned to engage at a point that provides sufficient blocking action throughout the majority of the drive element's movement range. The triggering position is designed with some tolerance, allowing partial variation in positioning while still achieving the desired abrupt movement function, reducing the need for high manufacturing precision.

Function Achieved in This Case
Enables abrupt transfer of locking bolts into closed or released positions mechanically, eliminating the need for electrical components and ensuring robust coupling and assembly.
Implementation Method 1
The drive element and the output element are preloaded or are preloaded against each other along the displacement direction by means of the elastic element (28)
Implementation Method 2
the output element is moved, in particular abruptly, from its first position to its second position due to the force acting on the output element via the elastic element (28)
