Door Module Carrier With Integrated Contacts for Simpler Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing module carriers for door systems require terminal blocks for electrical connections, leading to increased parts and assembly complexity, higher manufacturing costs, and higher electrical resistance due to numerous contact points.
Innovation Solution
Integrate connecting elements with multiple contact areas into the module carrier, eliminating the need for terminal strips and reducing contact points, allowing for simplified assembly and reduced parts count.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal blocks or printed circuit boards are used for electrical connections, then electrical connection options are provided, but the number of parts increases and manufacturing costs increase
Solution Approach 1:
The patent combines the terminal block function directly into the module carrier housing. The housing integrates contact points and connection elements, eliminating the need for separate terminal blocks or printed circuit boards. This merging reduces the total number of parts while maintaining reliable electrical connections between modules.
2Reliability
If terminal blocks are manufactured as an assembly with module carriers, then electrical connections are provided, but additional assembly steps are required
Solution Approach 1:
The terminal block functionality is merged into the module carrier housing itself. The housing is designed with integrated contact points and connection elements that are part of the housing structure, eliminating the need for separate assembly steps to attach terminal blocks.
3Reliability
If terminal blocks are installed during door system assembly, then electrical connections are established, but the assembly process becomes more difficult
Solution Approach 1:
The electrical connection elements are merged into the module carrier housing, allowing connections to be established through the housing structure itself. This integration simplifies the assembly process as installers work with fewer separate components.
4Reliability
If connection strips with multiple contact points are used, then electrical connections are provided, but electrical resistance increases and efficiency decreases
Solution Approach 1:
The patent extracts unnecessary intermediate contact points from the connection path. By using direct connection elements integrated into the housing, the design eliminates redundant contact points that would increase electrical resistance, thereby improving efficiency.

AI summary
The invention relates to a module carrier for receiving a module for door systems, in particular for door intercom systems, wherein the module carrier is designed for arrangement, in particular for grid arrangement, in or on a receiving housing, wherein the module carrier has a frame comprising frame parts in the form of longitudinal and transverse struts and at least partially surrounds a receiving space for receiving the module. Reduced component count, increased efficiency, and simplified assembly are achieved by the fact that at least one of the frame parts of the module carrier has at least one connecting element with at least two contact areas for indirect or direct electrical connection with at least one further module carrier and/or at least one module.The invention also relates to a modular unit with a module carrier and a module and a door system with a receiving housing for receiving an arrangement, in particular a griddled arrangement, of a plurality of modular units.
