Modular Sliding Gate Leaf Using C-Profile Beams
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The production of sliding gate door leaves requires a variety of differently sized profiles to absorb static and dynamic loads, leading to increased manufacturing and logistical efforts due to the need for complex machining or welding of one-piece large profiles.
Innovation Solution
A modular design for the door leaf using C-shaped profiles connected by parallel connecting profiles, allowing for the creation of a stable lower beam and upper rail with a simpler and cost-effective production process, where profiles can be easily connected without complex machining, and the use of identical connecting profiles reduces the number of required parts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If one-piece large profiles are used to absorb static and dynamic loads, then the load-bearing capacity is sufficient, but the manufacturing and logistical effort increases due to complex machining or welding requirements
Solution Approach 1:
The door leaf is divided into modular components: a lower beam, an upper beam, and vertical bars, each made from standardized profiles. The lower beam consists of two C-shaped profiles connected by connecting profiles, allowing the structure to be assembled from simpler parts rather than manufactured as a single complex piece, thereby reducing manufacturing effort while maintaining strength.
Solution Approach 2:
The connecting profiles serve multiple functions: they join the C-shaped profiles to form the lower beam, provide structural stability, and enable modular assembly. This universal component reduces the variety of parts needed and simplifies both manufacturing and logistics.
2Strength
If different sized profiles are produced for various door leaf sizes, then the load absorption is optimized, but the number of different profiles increases requiring more production effort
Solution Approach 1:
The door leaf system is segmented into standardized modular components (lower beam, upper beam, vertical bars) that can be combined in different configurations. This allows optimization for different load requirements without producing entirely different profiles, as the same standardized components are simply assembled in varying arrangements.
Solution Approach 2:
Instead of creating different profile types for different door sizes, the invention varies the parameters of assembly - the number, arrangement, and configuration of standardized modular components. This achieves customization for different load requirements while maintaining a limited set of standardized profile types.
3Strength
If complex machining or welding is used to connect profiles, then the connection strength is sufficient, but the production time and cost increase
Solution Approach 1:
Connecting profiles act as intermediary elements that join the C-shaped profiles. These connecting profiles are designed with simple geometric features that allow straightforward assembly without complex machining or welding, reducing production time while maintaining adequate connection strength through the intermediary joining mechanism.
