Solution Overview

Problem

Existing door drives require complex installation processes and are not adaptable to various installation situations due to rigid connection module designs, limiting their flexibility and versatility.

Innovation Solution

A door drive with a connection module that allows for selective feeding of connection lines from either the receiving body or the side, featuring a terminal part with snap-in projections and release buttons for easy cable management, and a distribution circuit board for voltage distribution, enabling flexible installation and configuration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the connection module has a fixed design with limited access points, then the manufacturing and assembly process is simpler, but the adaptability to different installation situations deteriorates

Engineering Contradiction:
Improveadaptability to installation situationsVSAvoidconnection module design complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection module is designed with multiple openings (first opening from receiving body direction, second opening from side direction) that serve multiple functions: power supply cable access, signal cable access, and adaptability to different mounting configurations. This universal design allows a single connection module variant to accommodate various installation situations without requiring multiple specialized designs.

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

2Adaptability or versatility

If the connection module provides multiple access points for connecting lines, then the adaptability to different installation situations improves, but the device complexity increases

Engineering Contradiction:
Improveflexibility in cable routingVSAvoidconnection module structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection module is segmented into distinct functional zones with specific openings for different cable types: the first opening (from receiving body direction) is optimized for power supply cables, while the second opening (from side direction) is optimized for signal cables. This segmentation allows each opening to be optimized for its specific purpose while maintaining overall module simplicity.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If standardized door drives are used without modifications, then production efficiency is higher, but the ease of operation during installation deteriorates due to limited flexibility

Engineering Contradiction:
Improveease of installationVSAvoidinstallation speed
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The connection module is pre-configured with multiple openings and internal routing channels during manufacturing, allowing installers to simply route cables through the appropriate opening based on the installation situation. This preliminary preparation eliminates the need for complex on-site modifications while maintaining installation flexibility, thereby improving both ease of operation and installation speed.

Inventive Principle:
Principle #10Preliminary action
