Grid-Based Modular Door Station With Frameless Functional Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing modular door communication systems have limited design flexibility and surface variation options, with standardized components that do not maximize the use of available viewing and operating area, and require additional framing and cover panels.
Innovation Solution
A modular assembly system with dimensionally standardized functional units and a grid design where the grid dimensions are defined as integer products of standardized minimum dimensions, allowing for a 'frameless' structure with interchangeable and customizable surface materials, and enabling maximum utilization of the visible area without additional framing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standardized components with fixed dimensions are used, then manufacturing and assembly are simplified, but design flexibility and surface variation options are limited
Solution Approach 1:
The system segments the door communication system into modular functional units (call buttons, mailboxes, cameras, loudspeakers) that can be independently selected and arranged. Each unit has standardized mounting dimensions but offers varied functional and surface design options, resolving the contradiction between manufacturing simplicity and design flexibility.
Solution Approach 2:
The grid-based carrier system provides a universal mounting platform that can accommodate multiple types of functional units with different functions and surface designs. The standardized grid pattern allows any combination of units to be mounted using the same carrier structure, achieving both manufacturing simplicity and design versatility.
2Stability of the object's composition
If additional framing and cover panels are used to enclose functional units, then structural stability and protection are improved, but the use of available viewing and operating area is reduced
Solution Approach 1:
The invention extracts the framing function from traditional enclosed structures and integrates it directly into the carrier grid system. The grid itself provides the structural framework, eliminating the need for separate cover panels and framing elements, thus maximizing the viewing and operating area while maintaining structural stability.
Solution Approach 2:
The carrier grid combines the structural support function and the mounting framework function into a single integrated element. This merging eliminates redundant framing components and allows functional units to be mounted directly on the grid, maximizing the usable area of the door system.
3Reliability
If a grid frame with webs is used to accommodate functional units, then structural support and positioning are provided, but aesthetic appearance and surface design variation are limited
Solution Approach 1:
The system allows different surface designs and materials to be applied to different local areas (individual functional units and carrier sections) while maintaining the standardized grid structure. This enables aesthetic customization without compromising the structural positioning accuracy provided by the grid.
Solution Approach 2:
The functional units can be arranged asymmetrically on the grid according to functional requirements and aesthetic preferences, while the grid itself maintains a regular symmetric pattern. This allows the underlying structure to provide reliable positioning while the surface arrangement achieves aesthetic variety.

AI summary
The system (1) has a carrier (2) exhibiting a pattern that is defined with square unit areas, where base sides of the square unit areas exhibit modular dimensions. A length (LE) and a width (BE) of recesses (AE) and a center distance between the recesses are dimensioned as an integral multiple of the modular dimensions according to the dimensions. The dimensions are defined as a quantity by a characteristic length or width dimension (EW) that is greater than a standardized minimum allowable dimension. A functional unit (4) and another functional unit are separable by the distance. The function units are designed as a bell push-button, a letterbox or a decoration module. An independent claim is also included for a function unit.
