Elevating Platform Mounting Plates for Shear-Based Stress Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing elevating platforms, particularly those used with utility trucks, often lack transparency, leading to reduced visibility for operators, which increases the risk of accidents due to limited awareness of their surroundings.
Innovation Solution
The integration of transparent or translucent materials in platform walls, panels, knee spaces, and doors, along with a mounting system that transforms tension stress into shear stress using a vertically elongated mounting plate with rounded corners and top and side tabs, enhances visibility and structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional opaque materials are used for platform walls, then structural strength is maintained, but operator visibility is reduced
Solution Approach 1:
The patent applies composite materials by combining transparent or translucent materials with structural support elements. The platform walls incorporate transparent panels that allow light transmission for improved visibility while maintaining structural integrity through the composite construction of the wall assembly.
2Strength
If a simple mounting plate is used, then device complexity is reduced, but stress distribution is insufficient leading to potential failure
Solution Approach 1:
The mounting system extends in multiple dimensions with tabs that wrap around the platform structure. The vertical elongation and lateral extension of mounting plates with tabs at multiple positions creates a three-dimensional stress distribution network that converts tension stresses into shear stresses, enhancing structural strength.
Solution Approach 2:
The mounting plates with tabs serve as intermediary elements that connect the platform structure to other components. These mounting plates distribute loads across multiple attachment points and transform stress types, acting as mediators between the platform body and attached equipment.
3Illumination intensity
If transparent materials are integrated throughout the platform, then visibility is improved, but manufacturing complexity increases
Solution Approach 1:
The platform is segmented into distinct components including transparent walls, floors, knee spaces, and doors that can be manufactured separately and assembled. This modular approach allows each component to be optimized for transparency while simplifying the overall manufacturing process through division of labor and sequential assembly.

AI summary
Mounting plates for elevating platforms, including a mounting apparatus with interior and exterior reinforcement components elongated vertically. The interior reinforcement piece includes an embedded bolt that extends from the interior reinforcement piece, through a wall of the platform, and through the exterior reinforcement component. The interior and exterior reinforcement components have a stepped construction to convert peel stress to shear stress.
