Variable Trigger Switch Point Unlocking Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional unlocking units for motor vehicle tailgates require different actuating elements with varying geometric configurations to achieve different switch points, leading to increased production complexity and inventory needs, as switch points are not adjustable based on the pivot angle of the actuating element relative to the housing.
Innovation Solution
An unlocking unit with a switch unit that can be reversibly positioned in multiple switch point positions relative to the housing, allowing for variable installation in different vehicles without the need for multiple actuating elements, by using a single switch unit and pivotable actuating element, where the switch unit is integrated in a holding element that can be precisely adjusted and locked in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different actuating elements with varying geometric configurations are used to achieve different switch points, then different trigger switch points can be realized, but the device complexity and inventory requirements increase
Solution Approach 1:
The patent applies the dynamics principle by making the switch unit position adjustable rather than fixed. The switch unit can be reversibly positioned in multiple switch point positions relative to the housing, allowing the same actuating element to trigger the switch at different pivot angles. This transforms a static configuration into a dynamic, adjustable one, eliminating the need for multiple different actuating elements while maintaining the capability to achieve different switch points.
Solution Approach 2:
The patent applies parameter changes by varying the position parameter of the switch unit relative to the housing. By changing the spatial position of the switch unit along the pivot arc of the actuating element, different trigger switch points are achieved. This parameter adjustment approach allows a single actuating element to serve multiple configurations, reducing device complexity and inventory requirements.
2Adaptability or versatility
If multiple actuating elements are produced and stored for different switch points, then different vehicle configurations can be supported, but production complexity and inventory needs increase
Solution Approach 1:
The patent applies universality by designing a single actuating element that can serve multiple functions across different vehicle configurations. By making the switch unit position adjustable, one actuating element can be used in all vehicle types, replacing the need for multiple specialized actuating elements. This multi-functional design simplifies production and inventory management while maintaining configuration flexibility.
Solution Approach 2:
The adjustable switch unit position transforms a static, configuration-specific component into a dynamic, universal component. The same actuating element can be installed in all vehicles, and the switch unit position can be adjusted during assembly or maintenance to match different vehicle requirements, eliminating the need for multiple inventory items.
3Device complexity
If the switch unit position is fixed relative to the housing, then the structure is simple, but different trigger switch points cannot be achieved without changing actuating elements
Solution Approach 1:
The patent introduces dynamic adjustability to the switch unit position while maintaining overall structural simplicity. The switch unit can be reversibly positioned in multiple locations along the housing, allowing the same simple structure to achieve different trigger switch points. This dynamic capability is achieved through a straightforward mounting mechanism that allows position adjustment without complicating the fundamental structure.

AI summary
An unlocking unit for unlocking an openable closure element of a motor vehicle, having a housing with a switch unit and an actuating element that can be pivoted relative to the housing and pivoted relative to the switch unit from an unactuated resting position into at least two actuating positions. It is provided that the switch unit is positioned in the housing and can be reversibly positioned in at least two different switch point positions relative to the housing, whereby different trigger switch points can be assigned the pivotable actuating element of the unlocking unit in accordance with a switch angle of the actuating element that can be pivoted out of the resting position.
