Angular Steering Lever for Load-Force-Independent Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load-force-independent triggering devices struggle to reliably release heavy loads under external force influences and extreme conditions, often resulting in undefined positions and requiring substantial effort, especially in underwater applications where environmental factors like rust, dirt, and friction pose additional challenges.
Innovation Solution
The design incorporates an angular steering lever with defined contact surfaces, a tension spring, and an electromagnetic locking device with a pressure-neutral solenoid actuator, ensuring the steering lever occupies only defined positions and can automatically open without external force input, overcoming obstructions and maintaining reliability under adverse conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a straight steering lever is used in prior art triggering devices, then the structure is simple, but the steering lever can assume undefined positions under extreme conditions leading to unreliable operation
Solution Approach 1:
The steering lever is designed with an angular geometry instead of a straight configuration. This angular design, combined with defined contact surfaces, ensures that the steering lever can only occupy specific predetermined positions, eliminating undefined positions and ensuring reliable operation under extreme conditions.
2Ease of operation
If load-force-independent triggering is implemented, then the triggering device can release loads regardless of load force, but the device requires substantial effort to overcome friction and external force influences
Solution Approach 1:
The triggering device is designed to automatically open without requiring external force input. The angular steering lever with defined contact surfaces creates a mechanical advantage that allows the device to overcome friction and external force influences automatically, eliminating the need for substantial manual effort while maintaining reliable operation.
3Reliability
If conventional triggering mechanisms are used, then the device structure is simpler, but they cannot reliably trigger under remote operation and external force effects
Solution Approach 1:
The angular geometry of the steering lever with defined contact surfaces creates predetermined positions that ensure reliable triggering regardless of external force effects. This geometric constraint mechanism provides robust triggering reliability for remote operations without requiring complex additional components.
4Device complexity
If the steering lever is not guided by fixed housing axes, then the device structure is simpler, but the steering lever assumes undefined positions leading to indissoluble positions under extreme conditions
Solution Approach 1:
Instead of using fixed housing axes for guidance, the invention employs an angular steering lever with defined contact surfaces that naturally constrain the lever to predetermined positions. This approach maintains structural simplicity while ensuring well-defined positions and eliminating indissoluble positions under extreme conditions.

AI summary
A load-force-independent triggering device for a load exerting a force on it that is held in a CLOSED position of the triggering device and released in an OPEN position of the triggering device includes: a housing; a triggering lever, which is connected to a triggering gear via a steering lever, the triggering lever being swivel-mounted on a first housing axis, the triggering gear being swivel-mounted on a second housing axis and the steering lever being swivel-mounted on a steering-lever axis on the triggering lever and on a second steering-lever axis on the triggering gear; a spring device acting on the triggering lever; and a locking device, by which the triggering device is fixed in the CLOSED position. The steering lever has an angular design, and, in the CLOSED position of the triggering device, contacts a first contact surface in the housing.
