Vehicle Engine Start Triggering Element Integrated with Authorization Receptacle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicle engine start devices with integrated authentication systems lack operability and safety, as they often require separate cabling and can lead to accidental engine starts due to the separation of the authorization unit and triggering element, limiting design freedom and user experience.
Innovation Solution
Mechanical connection between the triggering element and receptacle allows for actuation by translational displacement of the authorization unit, enabling a continuous movement sequence and optional interruption for safe engine starting, with the authorization unit serving as part of the operating element, reducing wiring complexity and enhancing haptic feedback.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the triggering element is arranged spatially separate from the receptacle, then separate cabling is required and the operator cannot perform continuous movement sequence, but this configuration increases device complexity and reduces ease of operation
Solution Approach 1:
The patent merges the triggering element and the receptacle into a single integrated unit. The triggering element is arranged directly on the receptacle, eliminating the need for separate cabling and enabling the operator to perform the authorization check and trigger activation in a continuous movement sequence without interrupting the operation.
2Reliability
If the authorization unit is placed in the receptacle and the triggering element is actuated separately, then the engine start can be controlled, but accidental engine starts may occur and the operator may be surprised
Solution Approach 1:
By integrating the triggering element directly on the receptacle, the system requires the operator to complete the authorization check by placing the authorization unit in the receptacle, and then perform the trigger activation as a continuous sequence on the same unit. This integration reduces the risk of accidental engine starts while maintaining operator control through deliberate sequential actions.
3Device complexity
If the triggering element is provided on the authorization unit, then the wiring is simplified, but the triggering element can only have very small dimensions and haptic sensation cannot be sufficiently provided
Solution Approach 1:
The patent integrates the triggering element on the receptacle rather than on the authorization unit itself. This allows the triggering element to be of sufficient size to provide adequate haptic sensation and dimensional characteristics, while still achieving wiring simplification by eliminating separate cabling between separate components.
4Ease of operation
If the triggering element and receptacle are mechanically connected, then continuous movement sequence is enabled and wiring is reduced, but the mechanical connection adds structural complexity
Solution Approach 1:
The patent implements a mechanical connection between the triggering element and receptacle through integration, where the triggering element is arranged directly on the receptacle. This unified structure enables continuous movement sequence for the operator while the integrated design itself simplifies the overall structure compared to separate components requiring complex interconnections.

AI summary
In a device for starting the engine of a motor vehicle with an authentication device comprising a user-carrying authorization unit (4,14) and a vehicle-side authorization verification device (5) with a receptacle for the authorization unit, and with a triggering unit comprising a triggering element (13) by actuating which an engine start can be triggered, the triggering element (13) and the receptacle are mechanically connected to each other in such a way that the triggering element (13) can be actuated by substantially translationally displacing the authorization unit (4,14) placed in the receptacle.
