Lift Gate Platform Stop Member Impact Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lift gate systems face issues with direct impact between the lift platform and the extension plate during the raising process, which can cause damage and require complex mechanisms to prevent buckling.
Innovation Solution
Incorporating stop members and shackle members that create a gap between the lift platform and the extension plate when the platform is raised, preventing direct contact and using adjustable support brackets to maintain alignment and prevent impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the lift platform is raised directly against the extension plate, then the platform reaches the selected level, but direct impact and damage occur between the platform and the extension plate
Solution Approach 1:
A stop member is introduced as an intermediary element between the lift platform and the extension plate. The stop member prevents direct contact between these two components when the platform is raised, thereby eliminating impact damage while maintaining proper alignment. The stop member absorbs the impact force and provides a controlled stopping point.
Solution Approach 2:
The stop member is positioned in advance to prevent direct impact between the lift platform and extension plate. By having the stop member in place before the raising operation, the system is prepared to cushion any potential impact, preventing damage before it occurs.
2Reliability
If complex mechanisms are added to prevent buckling, then damage prevention is improved, but device complexity increases
Solution Approach 1:
The stop member serves as a simple intermediary that prevents buckling and damage without requiring complex mechanisms. Instead of adding multiple components or complex control systems, a single stop member effectively prevents the harmful impact that would cause buckling.
Solution Approach 2:
The invention extracts the essential function of preventing buckling from a complex mechanism and simplifies it to a single stop member. By taking out only the necessary element (the stop member) that prevents buckling, the system achieves reliability without complexity.
3Strength
If the lift platform contacts the extension plate directly, then structural support is provided, but wear and damage increase
Solution Approach 1:
The stop member acts as an intermediary that prevents direct contact between the lift platform and extension plate. This eliminates wear between these components while the extension plate continues to provide structural support for the overall system.
Solution Approach 2:
The stop member is positioned beforehand to prevent direct contact between moving and stationary components. This cushioning effect prevents wear from occurring in the first place, extending the lifespan of the lift platform and extension plate.

AI summary
The present invention provides a lift gate system. In one embodiment, the lift gate system comprises a lift platform, a lifting mechanism, and at least one stop member. The lifting mechanism moves the lift platform between a raised position and a lowered position. The lift platform is substantially aligned with an extension plate when the lift platform is in the raised position. The stop members are positioned relative to the lift platform to provide a gap between the extension plate and the lift platform when the lift platform is in the raised position.
