Adjustable Safety Gate Width Using Overlapped Door Bodies
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing safety gates have fixed sizes, requiring customization for different door widths, leading to poor applicability and longer installation times.
Innovation Solution
A safety gate design with adjustable door bodies that allow for random width adjustment through a door rail mechanism and adjustment components, enabling direct use without customization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If safety gates have fixed sizes, then manufacturing and installation are simpler, but applicability is poor and customization is required for different door widths
Solution Approach 1:
The door bodies are designed with adjustable width through movable adjustment components that can be positioned at different locations along the door body length. This dynamic adjustability allows the safety gate to adapt to various door widths while maintaining a relatively simple overall structure, resolving the contradiction between adaptability and structural complexity.
Solution Approach 2:
The safety gate is divided into multiple door bodies with adjustment components that can be independently positioned. This segmentation allows each door body to be adjusted separately to match the required width, providing versatility without requiring complete customization of the entire gate structure.
2Manufacturing precision
If customization is required for different door widths, then fit is precise, but installation cycle is longer
Solution Approach 1:
The adjustment components are pre-installed on the door bodies at multiple predetermined positions. During installation, users only need to move these pre-positioned components to the appropriate locations rather than installing new components, which maintains fit precision while significantly reducing installation time.
Solution Approach 2:
The adjustment components are designed to be movable and repositionable during installation, allowing quick adaptation to different door widths without requiring precise custom manufacturing for each case, thus reducing installation time while maintaining adequate fit precision.
3Adaptability or versatility
If safety gates are designed for specific door widths, then structure is simpler, but applicability scope is limited
Solution Approach 1:
The safety gate is designed as a universal product that can fit multiple door widths through the adjustable door bodies. The standard manufacturing process produces door bodies with adjustment components that can be configured for various widths, eliminating the need for custom manufacturing while expanding applicability scope.
Solution Approach 2:
The door bodies are segmented with multiple adjustment components that can be positioned independently. This allows a single standardized door body design to serve multiple width requirements, maintaining manufacturing simplicity while expanding the range of applicable door widths.

AI summary
A safety gate, includes a door frame, a door rail mechanism, and a handle mechanism, wherein the door rail mechanism includes: two door bodies and adjustment components; the two door bodies are overlapped front and back, one side of one door body is hinged with the door frame, and the handle mechanism is arranged on other door body; the two door bodies are provided with a plurality of fixing holes matching to each other at intervals along width direction. The adjustment components pass through the fixing holes on two door bodies in sequence and are detachably connected with the fixing holes. By the means of changing the position of the adjustment components in the fixing holes of the door bodies, width of two door bodies in left and right directions can be changed randomly, so that the applicable range is wider.
