Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing accelerated loading road-testing devices cannot achieve heavy loads, which is necessary for simulating the long-term service performance of engineering infrastructure under heavy traffic and environmental conditions.
Innovation Solution
The device includes a plurality of loading mechanisms with a supporting frame, sliding assembly, and loading assembly. The loading assembly features a telescopic cylinder and loading head that can adjust to apply a load perpendicular to the road surface, and a horizontal supporting beam that can switch between static and sliding states to increase the applied load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Force
If a hydraulic cylinder is used as loading power, then the device structure is simple and easy to operate, but the maximum load magnitude cannot reach the magnitude of load applied by heavy truck, plane or train to the road surface
Solution Approach 1:
The loading mechanism is divided into multiple independent components: supporting frame, sliding assembly, and loading assembly. Each component performs a specific function, allowing the system to achieve heavy loads through coordinated action of segmented parts rather than a single oversized hydraulic cylinder.
Solution Approach 2:
The horizontal supporting beam is designed to switch between static and sliding states along the third direction. This dynamic capability allows the supporting frame to adjust its position and contribute to load application, enabling the system to reach magnitudes of load comparable to heavy vehicles while maintaining structural efficiency.
2Adaptability or versatility
If the loading head is fixed in position, then the device structure is simple, but the angle between the telescopic cylinder and sliding assembly cannot be adjusted to always apply load perpendicular to the road surface
Solution Approach 1:
The loading head is designed to be rotatable relative to the telescopic cylinder, allowing dynamic adjustment of the angle between them. This enables the loading head to always apply load in a direction perpendicular to the road surface, regardless of the position of the sliding assembly, while maintaining a relatively simple hinge connection rather than complex positioning mechanisms.
Solution Approach 2:
The loading head automatically adjusts its orientation through the hinge connection to maintain perpendicular load application to the road surface. The mechanism self-regulates the angle based on the road surface orientation without requiring external control or complex sensing systems.
