Foldable Safety Gate for Hoist Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for installing and dismantling lift systems with gates are time-consuming and labor-intensive, requiring manual assembly and posing risks of component loss and injury, especially in high-rise buildings where multiple gates are needed.
Innovation Solution
A foldable safety gate apparatus that includes a main gate body with a cantilever platform, side panels, and guard rails, designed for quick deployment and collapse, allowing efficient stacking and transportation, and can be lifted by a crane for secure installation without external parts or fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual assembly of individual gate components is used, then installation flexibility is maintained, but installation time increases significantly (4 hours per floor)
Solution Approach 1:
The patent combines multiple gate components (gate leaves, panels, hinges, fasteners) into a single pre-assembled modular unit. This integration eliminates the need for manual assembly of individual parts during installation, reducing installation time from 4 hours per floor to a fraction of that time, while maintaining the functional requirements of the gate system.
Solution Approach 2:
The gate components are pre-assembled and pre-configured into complete modular units at the manufacturing stage. All necessary connections, fasteners, and structural elements are prepared in advance, allowing for rapid deployment during construction without requiring on-site assembly operations.
2Ease of operation
If components are transported separately, then logistics flexibility is improved, but risk of component loss and misplacement increases
Solution Approach 1:
All gate components including leaves, panels, hinges, fasteners, and structural elements are integrated into a single modular unit. This ensures that no components are lost or misplaced during transportation, as everything is contained within one self-contained assembly that can be handled as a single item.
3Strength
If traditional gate structures are used, then structural integrity is maintained, but installation complexity increases
Solution Approach 1:
The patent integrates all structural elements (frames, supports, connecting joints) into a pre-assembled modular unit with built-in structural integrity. The complex structural connections are pre-established during manufacturing, presenting a simple drop-in solution during installation that maintains full structural strength without requiring complex on-site assembly procedures.
