Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle flap systems require multiple actuators and components for opening, closing, unlocking, and locking, leading to increased complexity and reduced reliability, along with higher friction and energy consumption.
Innovation Solution
A multi-bar system with an actuation kinematics driven by a single actuator, utilizing a deflection lever and engagement elements to achieve simultaneous opening, closing, unlocking, and locking of the vehicle flap, reducing the number of components and enhancing reliability while minimizing friction through an over-center position mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple actuators and components are used for opening, closing, unlocking, and locking the vehicle flap, then the reliability of the system increases, but the device complexity increases and the number of components increases
Solution Approach 1:
The patent combines multiple functions (opening, closing, unlocking, and locking) into a single integrated actuator and multi-bar mechanism. Instead of using separate actuators for each function, the invention merges them into one coordinated system where a single actuator controls all operations through the kinematic coupling of multiple bars and engagement elements.
Solution Approach 2:
The single actuator is designed to perform multiple functions simultaneously or sequentially. By controlling the deflection lever and engagement elements through one actuator, the system achieves universal functionality for opening, closing, unlocking, and locking operations, eliminating the need for dedicated actuators for each function.
2Reliability
If multiple actuators and components are used for opening, closing, unlocking, and locking the vehicle flap, then the reliability of the system increases, but the quantity of components increases
Solution Approach 1:
The patent combines multiple functions (opening, closing, unlocking, and locking) into a single integrated actuator and multi-bar mechanism. Instead of using separate actuators for each function, the invention merges them into one coordinated system where a single actuator controls all operations through the kinematic coupling of multiple bars and engagement elements.
3Ease of operation
If traditional guide rails and multiple sliders are used, then the vehicle flap can be opened and closed, but the friction increases and energy consumption increases
Solution Approach 1:
The patent replaces traditional guide rail and slider mechanisms with a multi-bar linkage system. Instead of relying on sliders moving within guide rails (which generate friction), the invention uses rotating bars connected through pivots and engagement elements, significantly reducing friction and energy consumption while maintaining operational capability.
4Ease of operation
If traditional drive mechanisms with multiple components are used, then the vehicle flap can be actuated, but the device complexity increases
Solution Approach 1:
The patent combines multiple functions (opening, closing, unlocking, and locking) into a single integrated actuator and multi-bar mechanism. Instead of using separate actuators for each function, the invention merges them into one coordinated system where a single actuator controls all operations through the kinematic coupling of multiple bars and engagement elements.

AI summary
The arrangement has a drive kinematics comprising a drive steering wheel (3) that is engaged with a flap kinematics and connected with a deflection lever (2). The deflection lever is driven by an actuator (1) and provided for closing and locking the flap kinematics or a vehicle flap during closing movement in an engaging unit (5) e.g. hook, of a locking mechanism. The actuator is designed as a drive cylinder that is electrically, pneumatically or hydraulically driven. An engaging counter element (4) of the locking mechanism is arranged at the deflection lever.
