Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking devices for machine systems lack user-friendly manual release mechanisms and compact designs, which hinders efficient actuation and increases the risk of manipulation.
Innovation Solution
A tumbler mechanism with a transmission element that can be moved between coupling and decoupling positions, allowing the blocking element to be unlocked independently without direct user contact, utilizing an auxiliary unlocking device and energy accumulators to ensure secure and efficient movement between locked and unlocked positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the blocking element is made directly accessible for manual release, then ease of operation is improved, but security against manipulation deteriorates
Solution Approach 1:
The patent introduces a transmission element as an intermediary between the auxiliary release and the blocking element. When the auxiliary release is actuated, it moves the transmission element from a coupling position to a decoupling position, which then allows the blocking element to be moved. This intermediary mechanism prevents direct access to the blocking element while still enabling manual release functionality.
2Reliability
If a transmission element is added to prevent direct access to the blocking element, then security against manipulation is improved, but device complexity increases
Solution Approach 1:
The transmission element serves multiple functions: it acts as a security mechanism to prevent direct access to the blocking element, serves as a transmission mechanism to transfer motion from the auxiliary release to the blocking element, and provides a coupling/decoupling functionality. By combining these functions into a single element, the patent reduces overall device complexity despite adding the security feature.
3Reliability
If the transmission element is kept in constant engagement with the blocking element, then reliability of locking is improved, but ease of manual release deteriorates
Solution Approach 1:
The patent makes the engagement between the transmission element and blocking element dynamic rather than static. The transmission element can be in a coupling position where it is engaged with the blocking element for reliable locking, or a decoupling position where it is disengaged to allow manual release. This dynamic engagement state is controlled by the auxiliary release mechanism.
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
Enhances user-friendliness and security by preventing direct access to the blocking element, ensuring secure locking and easy unlocking through a compact design that minimizes friction and noise, while maintaining high security against manipulation.
Implementation Method 1
a first energy store (13), which, in the locking position of the locking element, has energy which ensures that when the transmission element changes from the coupling position to the decoupling position, the locking element moves from the locking position to the unlocking position
Implementation Method 2
a second energy store (39), which in the uncoupled position has an energy which ensures that the transmission element moves back into the coupled position

AI summary
The invention relates to a tumbler (10) for an access protection device (1) of a closable spatial region (2) of a mechanical system (3), with a blocking element (20) which is movable within a housing (11) between a locking position (4) and a release position (5) by means of drive (12), a transmission element (31) which is arranged between the drive (12) and the blocking element (20), and an emergency release (30) with which a movement of the blocking element (20) between the positions can be brought about independently of the drive (12). For this purpose, it is provided according to the invention that, via an actuation of the emergency release (30), the transmission element (31) is movable between a coupling position (6) and a decoupling position (7), in the coupling position (6) the transmission element (31) is operatively connected to the blocking element (20) and in the decoupling position (7) the transmission element (31) is detached from the blocking element (20), as a result of which it is possible for the blocking element (20) to move out of the locking position (4) into the release position (5).
