Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring and control systems for door elements, such as roller or sectional doors, require significant effort and resources for safety regulation compliance and maintenance due to centralized control structures, which are complex and costly.
Innovation Solution
A decentralized control system where the master function can be determined or changed during operation, utilizing a Bluetooth or WLAN radio network with a master component that initiates communication, allowing distributed control functions and enabling internet connectivity through external devices like smartphones for monitoring and control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized control structure is used for monitoring and control systems, then control functions can be集中 managed, but the system complexity and cost increase significantly
Solution Approach 1:
The control system is segmented into multiple electronic components (drive control unit, monitoring sensor, safety sensor, display device) that can independently function. Each component has specific control functions distributed across them, eliminating the need for a single centralized control unit while maintaining reliable control management.
Solution Approach 2:
The master function in the radio network can be dynamically assigned to different electronic components based on operational needs. This dynamic allocation allows the system to adapt to different operational states while maintaining simplified control structure, resolving the contradiction between reliable control management and system complexity.
2Ease of operation
If a dedicated control unit is implemented, then control functions can be centralized, but the device complexity and cost increase
Solution Approach 1:
The functions of a dedicated control unit are merged into the existing electronic components already present in the door element system. The drive control unit, monitoring sensor, safety sensor, and display device all participate in control functions, eliminating the need for an additional dedicated control unit while maintaining ease of operation.
Solution Approach 2:
Existing electronic components are given multiple functions. For example, the drive control unit not only controls the drive mechanism but also participates in the radio network as a slave organ and can potentially serve as a master organ. This multi-functionality eliminates the need for dedicated control units while maintaining centralized control capabilities.
3Adaptability or versatility
If internet connectivity is added through external devices, then remote access and troubleshooting are enabled, but system complexity increases
Solution Approach 1:
A smartphone or other mobile device serves as an intermediary between the door element control system and the internet. The communication element in the electronic components establishes a local radio network (Bluetooth/WLAN) with the smartphone, which then provides internet connectivity. This intermediary approach enables remote access without directly integrating complex internet infrastructure into the door element system.
Solution Approach 2:
The smartphone serves multiple functions: it acts as a communication element establishing the radio network, provides internet connectivity, enables remote monitoring and control, and allows troubleshooting. This multi-functional use of a common device (smartphone) enables versatile remote access capabilities without adding dedicated infrastructure complexity to the door element system.
