Motorized Sliding Gate Leaf with Internal Actuator
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorized sliding gates face issues with durability, space efficiency, and ease of installation and maintenance, particularly due to the arrangement of motorized units and racks which are prone to deterioration and require complex adjustments.
Innovation Solution
The proposed solution involves housing motorized means, including a carrier wheel, inside a hollow portion of the sliding gate leaf, which reduces exposure to external hazards, eliminates the need for a rack, and simplifies the structure for easier installation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If motorized unit and rack are installed externally on the gate leaf, then the gate can be motorized for automated operation, but the motorized components are exposed to external hazards and prone to damage
Solution Approach 1:
The motorized unit is nested inside the hollow upright of the gate leaf, with only the carrier wheel projecting outward to engage with the guide rail. This nesting approach protects the motorized components from external hazards such as sand, debris, and accidental impacts while maintaining the gate's motorized functionality.
2Ease of operation
If rack and pinion system is used for motorization, then the gate can be moved between open and closed positions, but the structure becomes complex and requires difficult assembly and adjustment
Solution Approach 1:
The rack component is extracted from the system and replaced with a guide rail that is already part of the gate's support structure. The motorized unit with carrier wheel directly engages with this guide rail, eliminating the need for a separate rack and pinion mechanism. This simplifies the overall structure and makes assembly and maintenance easier.
Solution Approach 2:
The guide rail serves dual functions: it provides structural support for the gate leaf and simultaneously acts as the rack for the motorized unit to engage with. This multi-functionality reduces the number of components needed and simplifies the motorization system.
3Adaptability or versatility
If motorized unit is installed externally on the gate, then the gate can be automated, but more space is required for installation and the gate size increases
Solution Approach 1:
The motorized unit is housed within the hollow upright of the gate leaf, utilizing the existing internal space of the gate structure. This nesting approach allows the gate to be motorized without increasing its external dimensions, making it adaptable to various gate types and installation spaces.
