Solution Overview
Problem
Existing door drives for buildings require complex and cumbersome assembly processes, often necessitating overhead work and the use of multiple specialized tools, which complicates installation and maintenance, especially for fully automatic systems with high dead weight and varying degrees of automation.
Innovation Solution
A modular door drive system comprising a connection module, drive module, and main module, secured to a mounting plate using latching means, allowing for flexible assembly and easy interchangeability of modules without additional tools, simplifying the assembly process and enabling adaptation to different installation spaces and specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional screw connections are used to attach door drive modules to the mounting plate, then reliable mechanical connection is achieved, but assembly complexity and installation time increase significantly
Solution Approach 1:
The patent replaces the traditional screw connection system with a latching mechanism system. The latching means comprise latching elements that engage with corresponding recesses in the mounting plate, eliminating the need for screws and threaded holes. This substitution maintains mechanical connection reliability while dramatically simplifying the assembly process, as modules can be attached by simple latching actions rather than requiring tools and multiple fastening operations.
Solution Approach 2:
The patent extracts the fastening function from the traditional screw connection system and implements it through dedicated latching means integrated into the module structure. The latching elements are specifically designed to engage with the mounting plate without requiring separate fasteners, thereby reducing assembly complexity while maintaining connection reliability.
2Reliability
If multiple specialized tools are used for assembling door drives with varying degrees of automation, then proper installation is achieved, but installation time and skill requirements increase
Solution Approach 1:
The patent designs the latching means to be universally applicable across all module types (connection module, drive module, main module) regardless of the door drive's automation level. The same latching mechanism used for simple mechanical door closers also works for fully automatic door drives with motors and control units. This universal design eliminates the need for specialized tools for different automation levels, reducing both installation time and skill requirements while maintaining installation quality.
3Ease of manufacture
If modules are designed with fixed configurations, then manufacturing simplicity is maintained, but adaptability to different installation spaces and specifications is reduced
Solution Approach 1:
The patent segments the door drive into separate functional modules (connection module, drive module, main module) that can be independently manufactured with simple, standardized designs. Each module has standardized latching interfaces that allow them to be combined in different configurations. This segmentation enables simple manufacturing of individual modules while providing high adaptability through modular assembly to suit different installation spaces and automation requirements.
Solution Approach 2:
The patent creates a dynamic modular system where the door drive configuration can be adapted by selecting and assembling different modules. The latching means enable easy reconfiguration and replacement of modules to match specific installation requirements, whether for mechanical closers or fully automatic door drives, without requiring custom-designed fixed configurations for each application.
4Manufacturing precision
If comprehensive assembly instructions and preparation are required before on-site installation, then assembly accuracy is improved, but installation time and complexity increase
Solution Approach 1:
The patent incorporates preliminary action by pre-designing the latching interfaces and means during the manufacturing phase. The latching elements and their corresponding recesses are precisely formed in the factory, ensuring proper alignment and fit. This preliminary preparation of the connection geometry eliminates the need for complex on-site alignment procedures, allowing installers to simply attach modules without extensive preparation or specialized knowledge, thereby maintaining assembly accuracy while greatly improving on-site ease of operation.
