Anti-Tipping Support Element for Industrial Trucks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-tilt devices for three-wheeled vehicles, such as industrial trucks, require lifting to assemble or adjust, which is time-consuming and inconvenient, especially when dealing with wear on wheels that affect ground clearance.
Innovation Solution
An anti-tilt arrangement that allows the support element to be mounted and adjusted on the vehicle frame without lifting, using a holder with legs and a prismatic support element that can be secured in different positions to maintain ground clearance, enabling secure anti-tilting without twisting, and allowing for adjustment without tools while the vehicle is on the ground.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the anti-tilt device is mounted from below with the screw head facing the ground, then the vehicle gains anti-tilting support, but the screw head becomes inaccessible for assembly and adjustment when the vehicle is on the ground
Solution Approach 1:
The patent inverts the mounting orientation by attaching the support element to the upper side of the vehicle frame instead of the lower side, allowing the screw head to face upward and be accessible for assembly and adjustment while the vehicle is on the ground
2Ease of manufacture
If the vehicle is lifted for assembly or adjustment of the anti-tilt device, then the support element can be installed or adjusted, but time is lost during assembly and maintenance work
Solution Approach 1:
The patent enables self-service assembly and adjustment by positioning all fastening operations on the upper side of the vehicle frame, allowing maintenance personnel to service the anti-tilt device without requiring external lifting equipment or raising the vehicle
3Ease of operation
If the support element is not rotationally fixed, then it can be easily installed, but it may twist relative to the mount or vehicle frame when the vehicle experiences tipping tendency
Solution Approach 1:
The patent merges the support function with the anti-rotation function by designing the support element to contact both the upper side of the vehicle frame and the ground simultaneously, creating a stable triangular support structure that prevents both tipping and rotation
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables quick and efficient assembly, maintenance, and adjustment of anti-tilt devices, reducing downtime and labor, while ensuring the vehicle remains stable against tipping through adjustable ground clearance, even with wear on wheels.
Implementation Method 1
the support element is supported in a rotationally fixed manner on the holder and/or on the vehicle frame. This ensures that the support element is prevented from twisting relative to the mount or to the vehicle
Implementation Method 2
the support element is displaced along the ground surface, so that in addition to the acting support forces, frictional forces also act on the support element, which exert a torque on the support element

AI summary
The vehicle has an anti-tipping arrangement (28) comprising a support element (40) for anti-tipping supporting of the vehicle at a base (34) during anti-tipping of the vehicle. The support element is fastened to a holder (36) at a lower side of a vehicle frame of the vehicle. The anti-tipping arrangement is formed such that the support element is mounted and/or adjusted in a vehicle driving operation standby mode, in which the vehicle stays with a wheel (18) on the base. The support element is supported at a mounted state on the holder and/or at the vehicle frame.
