Closure Device With Blocking Mechanism For Amusement Restraints
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle restraint systems lack the ability to adjust securely to individual users and ensure simplified operation while preventing unintentional release during vehicle movements.
Innovation Solution
A closure device featuring a locking mechanism with a first and second connecting member and a blocking device, providing a releasable coupling that transitions to a non-releasable coupling through a predetermined force or movement, utilizing geometric adaptations and positioning members like springs for secure engagement and adjustable counterforces, and incorporating a sensor for monitoring the coupling state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional button release mechanism is used, then the operation is simple, but the restraint system cannot prevent unintentional release during vehicle movements
Solution Approach 1:
The closure device transitions from a static coupling state to a dynamic locked state through relative movement. The locking device moves from a first position where coupling is releasable to a second position where coupling is non-releasable, creating a dynamic system that adapts its release characteristics based on operational phase
Solution Approach 2:
The release function is segmented into two distinct phases: initial coupling with releasable connection for adjustment, and final locked state with non-releasable connection for security. This segmentation allows the system to provide both ease of operation during setup and reliability during use
2Reliability
If a locking mechanism is added to prevent unintentional release, then the reliability improves, but the device complexity increases
Solution Approach 1:
The locking function is merged with the existing coupling mechanism. The locking device integrates the coupling and locking functions into a single integrated component that performs both functions through its movement between positions, rather than adding a separate locking mechanism
Solution Approach 2:
The locking device serves multiple functions: it provides the coupling between connecting members, enables the transition from releasable to non-releasable connection, and prevents unintentional release. This multi-functionality reduces the need for additional components
3Ease of operation
If a releasable coupling is provided for easy release, then the ease of operation improves, but the restraint system cannot ensure secure locking during ride
Solution Approach 1:
The coupling characteristics dynamically change based on the position of the locking device. In the first position, the coupling is releasable for easy operation. In the second position, the coupling becomes non-releasable for security during ride, creating a dynamic adaptation to operational requirements

AI summary
A closure device for closing and locking a restraint system, such as a restraint system for an amusement vehicle, includes a blocking device, and a locking device having a first connecting member and a second connecting member. The locking device and the blocking device interact in such a way that, in at least a first position of the locking device relative to the blocking device, the first connecting member is releasable coupled to the second connecting member. Furthermore, in at least a second position of the locking device relative to the blocking device, the blocking device prevents release of the first connecting member from the second connecting member. In some examples, the second position includes the locking device being inserted at least partially into the blocking device.
