Outdoor Mobile Loading Dock Open-Grate Ramp Solar Hydraulic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile loading docks face issues with traction and safety due to slippery solid ramp surfaces, especially in rainy, icy, or snowy conditions, which can hinder vehicle mobility and pose safety risks.
Innovation Solution
A mobile loading dock with an open-grate platform and a planar ramp member that includes a solar-powered hydraulic system and an integrated dock leveler with a hinged safety barrier, allowing for improved traction and mobility by using an open-grate surface that allows snow and ice to fall through, and a hydraulic system that prevents 'stump out' issues and provides safe bridging between the ramp and trailer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a solid ramp surface is used, then the structure is simple and continuous, but traction is poor and snow/ice accumulation occurs
Solution Approach 1:
The patent applies an open-grate surface structure instead of a solid ramp surface. This porous configuration allows snow and ice to fall through the gaps, preventing accumulation on the surface. Simultaneously, the open structure provides superior traction for vehicle tires compared to smooth solid surfaces, directly resolving the contradiction between reliability (traction) and device complexity.
2Productivity
If a solid surface is used, then the surface is continuous and simple, but snow and ice removal is difficult and time-consuming
Solution Approach 1:
The open-grate surface structure enables snow and ice to pass through the gaps naturally, eliminating the need for manual or mechanical removal operations. This dramatically improves productivity by making snow removal unnecessary, while the structural complexity remains limited to the grate configuration itself.
3Power
If electrical systems are used for hydraulic power, then the system has high power output, but electrical connections are required and mechanical failures increase
Solution Approach 1:
The patent replaces electrical hydraulic systems with a manual crank-operated hydraulic system. This substitution eliminates the need for electrical connections, generators, and associated wiring in remote outdoor locations. The mechanical crank system provides sufficient hydraulic power for dock leveler operation while significantly improving reliability by removing electrical components that are susceptible to failure in harsh environments.
