Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door drive systems lack sufficient break-in protection and fail to effectively manage moisture, leading to mold growth due to insufficient self-locking mechanisms and tight sealing, which can prevent moisture escape.
Innovation Solution
A drive system with an electric drive and a locking element that blocks the electric actuator, combined with a sensor-controlled ventilation function to manage humidity, ensuring secure locking and air exchange, and utilizing a laser diode for parking position display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the door is tightly sealed to improve security and insulation, then break-in protection is improved, but moisture cannot escape leading to mold growth
Solution Approach 1:
The patent applies dynamics by making the sealing state changeable rather than fixed. The door sealing system transitions between sealed and vented states based on moisture sensor feedback, allowing the system to adapt to different environmental conditions and prevent mold growth while maintaining security when needed
2Adaptability or versatility
If the electric drive is made movable and controllable to enable ventilation positioning, then ventilation function is improved, but break-in protection is reduced due to insufficient self-locking
Solution Approach 1:
The patent introduces a locking element as an intermediary component between the door and the frame. This locking element acts as a mediator that provides mechanical security by engaging with the frame when the door is in the closed position, compensating for the insufficient self-locking of the electric drive while allowing ventilation positioning capability
3Reliability
If a separate locking mechanism is added to improve break-in protection, then security is improved, but device complexity increases
Solution Approach 1:
The patent merges the locking element with the existing door structure and electric drive system. The locking element is integrated into the door assembly and works in conjunction with the electric drive's positioning capabilities, combining security functionality with the existing ventilation control system rather than adding a completely separate mechanical locking mechanism
4Reliability
If the door is kept in closed position to maintain security, then break-in protection is improved, but moisture accumulates leading to mold growth
Solution Approach 1:
The patent implements feedback control through moisture sensors that continuously monitor the environment inside the building. When moisture levels exceed a threshold, the system automatically transitions the door to a vented position to reduce moisture. When moisture levels are acceptable, the door returns to the closed secure position, creating a dynamic feedback loop that balances security and moisture management
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system provides enhanced burglary protection and prevents mold growth by securely locking the door and controlling ventilation based on moisture levels, while also offering a visible parking position display with reduced design complexity.
Implementation Method 1
The locking element has a lifting magnet. The assigned to the locking element the stop is formed by a co-rotating with the rotor of the electric drive stop disc.
Implementation Method 2
the or each transmission element is formed by a laser diode. The laser diode produces sharply focused spot beams, with which the respective set position can be displayed accurately.

AI summary
The invention relates to a drive system (1) for a gate (2) closing an opening in a building, comprising a drive unit with an electric drive by means of which the gate (2) can be moved between an open position and a closed position. The gate (2) can be moved into a ventilation position in which it leaves only a ventilation slot open at the building opening. The movement of the gate (2) between the closed position and the ventilation position is controlled by sensor signals from a sensor that measures the humidity in the building. In the ventilation position and/or the closed position, the gate (2) is secured against manual opening by a locking element (16) that blocks the electric drive.
