Bus System for Window Fitting Locking Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fitting systems for structural elements like windows and doors with motorized locking units are limited by high cabling and parameterization efforts, requiring complex individual control lines for each unit, which complicates assembly, maintenance, and functionality.
Innovation Solution
A bus system is introduced, allowing locking units to communicate and transmit complex information via a bus protocol, enabling expanded functionality, easy expansion, and enhanced security through 'plug and play' capabilities, energy supply, and firmware updates, with communication interfaces for direct control and encryption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual control lines are provided for each locking unit to transmit signals beyond simple on/off signals, then the functionality and signal transmission capability are improved, but the wiring complexity and parameterization effort increase significantly
Solution Approach 1:
Multiple control lines for signal transmission are merged into a single bus line that can carry multiple signals simultaneously. The locking units are connected in parallel to this common bus line, eliminating the need for individual control lines for each unit while maintaining the ability to transmit complex signals beyond simple on/off commands.
Solution Approach 2:
The bus line serves multiple functions: it provides power supply to all locking units, transmits control signals, and carries status feedback. This multi-functional approach replaces the traditional separate wiring for power and control signals, reducing overall wiring complexity while enhancing functionality.
2Reliability
If multiple locking units are installed on a window to enhance security, then the burglary protection is improved, but the operating force required for manual operation increases
Solution Approach 1:
The manual mechanical operation of multiple locking units is replaced with an electrical actuation system. A single electrical signal transmitted via the bus line can simultaneously actuate multiple locking units, eliminating the need to manually apply operating force to each individual locking element while maintaining enhanced security through multiple locking points.
3Ease of manufacture
If a bus system is implemented for communication between locking units, then the ease of assembly and expansion is improved, but the device complexity increases due to bus protocol implementation
Solution Approach 1:
The bus system is designed with automatic address assignment and self-configuration capabilities. When locking units are connected to the bus line, they automatically receive unique addresses and configure themselves without requiring manual parameterization or complex setup procedures. This self-service approach simplifies assembly while managing the inherent protocol complexity internally.

AI summary
A hardware system for a building component comprising a frame and a movable sash includes at least two locking units, which, in the assembled state, are designed to releasably fix the sash at different points on the frame and each have a locking element, an electromechanical drive for adjusting the locking element at least between a release position and a locking position, and a control device. The hardware system includes a bus system, wherein the at least two locking units are configured as bus participants of the bus system and are designed to transmit data between the control devices of the at least two locking units via a bus line using a bus protocol.
