Panel Shutter Deformation Detection and Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Panel shutters with rigid shutter elements are prone to damage due to deformations, which can lead to malfunction and further damage when deformed elements contact the lintel or wall, causing potential tearing or inner layer damage.
Innovation Solution
A detection arrangement using a transmitter-receiver assembly is integrated to detect deformations in shutter elements, allowing for altered operation to prevent damage, comprising transmitters and receivers embedded in side rails to emit and receive detection signals, with a controller to trigger reactions such as stopping the door blade movement upon deformation detection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a panel shutter with rigid shutter elements is used, then security and protection are improved, but the risk of damage from deformation increases
Solution Approach 1:
The detection arrangement is installed to detect deformations before they cause serious damage. The system proactively identifies deformed shutter elements and triggers a warning signal or stops the shutter operation in advance, preventing the deformation from worsening or causing catastrophic failure.
Solution Approach 2:
The detection arrangement provides continuous monitoring feedback on the condition of shutter elements. When a deformation is detected, the system responds by issuing a warning signal or stopping operation, creating a closed-loop control system that prevents damage accumulation.
2Reliability
If a detection arrangement is added to detect deformations, then damage prevention is improved, but device complexity increases
Solution Approach 1:
The detection arrangement replaces complex mechanical monitoring systems with optical or electromagnetic sensing technology. This substitution simplifies the overall system while providing more reliable deformation detection capability.
Solution Approach 2:
The detection arrangement is designed to serve multiple functions: detecting deformations, generating warning signals, and potentially controlling shutter operation. This multi-functionality reduces the need for separate systems and minimizes overall device complexity.
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 detection arrangement effectively identifies and mitigates deformations, preventing further damage by stopping the door blade before it contacts the lintel or other elements, reducing the risk of serious malfunctions and damage.
Implementation Method 1
The transmitter receiver assembly comprises at least one transmitter and at least one receiver. Preferably the transmitter is designed and arranged to emit a detection signal towards the receiver which is designed and arranged for receiving the detection signal.

AI summary
The invention relates to a panel shutter (10) for opening and closing a doorway (15) having a door blade (11), the door blade (11) comprises several rigid shutter elements (12) which are hinged with each other. Further damage to the panel shutter (10) caused by a deformation (22) of the door blade (11) and/or at least one shutter element (12) is avoided by a detection arrangement (24) for detecting a deformation (22) of at least one shutter element (12).
