Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing underride protection assemblies for tipper vehicles face issues with unreliable operation due to exposure to weather and contamination, increased complexity leading to high maintenance costs, and risks of incorrect manual operation, particularly when the underride protection barrier needs to be moved between operating and release positions during tipping operations.
Innovation Solution
An underride protection assembly with a direct mechanical coupling to the tipper body, utilizing a lever and deflection arrangement that automatically moves the underride protection barrier into its release position during tipping and back to the operating position without manual or additional actuation, reducing the need for hydraulic, pneumatic, or electric components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the underride protection barrier is made movable between operating and release positions, then the ease of operation during tipping is improved, but the reliability deteriorates due to jamming and tilting from friction and weather exposure
Solution Approach 1:
The underride protection barrier automatically moves between operating and release positions based on the tipping state of the tipper body, without requiring manual operation or complex actuation systems. The system serves itself by utilizing the mechanical coupling between the tipper body's tipping movement and the barrier's position change, eliminating the need for external control while ensuring reliable operation.
Solution Approach 2:
The patent removes complex actuation systems (hydraulic, pneumatic, or electric components) and manual operation mechanisms from the underride protection barrier system. By extracting these unnecessary components, the system achieves both ease of operation and high reliability, as the barrier simply responds passively to the tipping motion through the mechanical coupling via the deflection arrangement and lever arm.
2Ease of operation
If complex actuation systems (hydraulic, pneumatic, electric) are used to move the underride protection barrier, then the ease of operation is improved, but the device complexity increases leading to higher manufacturing and maintenance costs
Solution Approach 1:
The system automatically responds to the tipping state of the tipper body without requiring complex actuation systems. The mechanical coupling through the deflection arrangement and lever arm enables the barrier to move on its own based on the tipping motion, eliminating the need for hydraulic, pneumatic, or electric components while maintaining ease of operation.
Solution Approach 2:
The patent extracts and removes all complex actuation systems (hydraulic, pneumatic, electric components) from the underride protection barrier system. This extraction simplifies the device significantly, reducing manufacturing and maintenance costs while the barrier still moves easily in response to tipping through the simple mechanical coupling.
3Device complexity
If manual operation of the underride protection barrier is used, then the device complexity is reduced, but the reliability deteriorates due to risks of incorrect operation or forgetting to return to operating position
Solution Approach 1:
The underride protection barrier automatically moves between operating and release positions based on the tipping state of the tipper body. The mechanical coupling ensures that when the tipper body tips, the barrier moves to the release position, and when the tipper body returns to horizontal, the barrier returns to the operating position. This self-service mechanism eliminates manual operation while ensuring reliable and consistent positioning without human error.
