Solution Overview

Problem

The existing door drives face challenges in simplified assembly and flexibility due to their ergonomic working position, high dead weight, and the need for variously dimensioned systems for different door installations, which complicates adaptation and specification changes during installation.

Innovation Solution

A modular door drive system comprising a connection module, drive module, and main module, which can be individually locked to a mounting plate using latching means, allowing for flexible assembly and adaptation without prior specific door drive provision, simplifying the assembly process and eliminating the need for complex screwing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If door drives are pre-assembled as complete units, then assembly speed is improved, but adaptability to different installation locations deteriorates

Engineering Contradiction:
Improveassembly speedVSAvoidadaptability to different installation locations
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The door drive is divided into separate modular components (motor unit, gear unit, spring energy store) that can be independently manufactured and then assembled on-site. This segmentation allows each module to be optimized for production while the final assembly can be adapted to different installation locations using the mounting plate with multiple attachment points.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides dynamic adaptability through the mounting plate design that allows different modules to be attached in different configurations depending on the installation location and door type, while maintaining standardized connection interfaces for efficient assembly.

Inventive Principle:
Principle #15Dynamics

2Extent of automation

If door drives are designed with high automation degree, then functional capability is improved, but weight increases

Engineering Contradiction:
Improvedegree of automationVSAvoiddead weight
Core Design Contradiction:
Extent of automationVSWeight of moving object

Solution Approach 1:

The automated door drive system is segmented into separate functional modules (motor unit, gear unit, spring energy store, mounting plate). This modularization allows the system to achieve high automation functionality while distributing the weight across separate components that can be installed progressively, reducing the ergonomic burden during assembly.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple differently dimensioned door drives are used for different doors, then adaptability to different door types is improved, but device complexity increases

Engineering Contradiction:
Improveadaptability to different door typesVSAvoidvariety of door drive systems
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mounting plate is designed as a universal base component with multiple attachment points and standardized interfaces that can accommodate different door drive modules. This universal mounting system allows the same basic platform to support various configurations for different door types, eliminating the need for completely different door drive systems while maintaining adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Manufacturing precision

If assembly requires overhead work in unergonomic positions, then installation precision is improved, but ease of operation deteriorates

Engineering Contradiction:
Improveinstallation precisionVSAvoidease of assembly
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The door drive is segmented into smaller modular units that can be handled more easily during assembly. The mounting plate provides a stable base that remains fixed on the wall or door frame, allowing modules to be attached in a systematic sequence that reduces the need for difficult overhead positioning while maintaining installation precision through standardized mounting holes and alignment features.

Inventive Principle:
Principle #1Segmentation

AI summary

The drive (1) has a mounting plate (2) on which a door drive structure is arranged. The door drive structure is module-like designed and has a connection module (3), a drive module (4) and a main module (5) which are snapped with the mounting plate by an attached locking unit (6). A locking unit (7) is provided between the connection module, the drive module and/or the main module to enable locking of the connection, drive and main modules below each other. Locking units (6, 7) have a goose-neck locking hook that is in engagement with an opposite lying locking opening. An independent claim is also included for a method for assembling a door drive.
