Rubber Caterpillar Support Frame for Faster Track Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing caterpillar changing systems for vehicles lack efficiency and safety due to the need for non-dedicated equipment, resulting in variable replacement times and installation risks, especially when dealing with rubber caterpillars.
Innovation Solution
A caterpillar changing apparatus comprising a floor frame, a moving frame, and a supporting unit that includes upper, lower, side, and inclined supporting units to maintain the shape of the caterpillar, allowing for easy installation and removal by reducing friction and enabling posture adjustments, thereby facilitating safer and faster operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If non-dedicated equipment such as a forklift is used to change the rubber caterpillar, then the replacement operation can be performed, but the replacement time and installation risk vary depending on the operator's work skill level
Solution Approach 1:
The caterpillar changing apparatus is divided into multiple independent functional modules: a moving frame for positioning, a supporting unit with multiple supporting bodies to hold the caterpillar, and a floor frame for stability. This segmentation allows each module to perform its specific function independently, enabling consistent operation regardless of operator skill level and improving both replacement speed and installation consistency.
2Loss of time
If a dedicated caterpillar changing apparatus is designed, then replacement time and installation consistency can be improved, but the device complexity increases
Solution Approach 1:
The moving frame serves multiple functions: it provides mobility to position the apparatus, supports the supporting unit, and enables the caterpillar to be moved between the apparatus and the vehicle. This multi-functionality reduces the need for separate dedicated components, thereby reducing overall device complexity while still achieving fast and consistent caterpillar replacement.
Solution Approach 2:
The apparatus incorporates movable components including the moving frame that can translate along the vehicle and the supporting unit that can adjust its position. This dynamic design allows the apparatus to adapt to different caterpillar positions and sizes, improving operational efficiency without requiring an overly complex fixed structure.
3Device complexity
If the caterpillar is supported without maintaining its shape, then the supporting structure can be simpler, but the caterpillar may deform or misalign during installation
Solution Approach 1:
The supporting unit comprises multiple supporting bodies (first, second, third, and fourth supporting bodies) positioned at different locations along the caterpillar. Each supporting body provides localized support at critical points, maintaining the caterpillar's shape and alignment without requiring a complex continuous support structure. This localized support approach ensures proper installation alignment while keeping the supporting structure relatively simple.

AI summary
A caterpillar changing apparatus includes a floor frame; a moving fame movable with respect to the floor frame; and a supporting unit including at least one body, the supporting unit provided on the moving frame and configured to support a caterpillar to maintain a shape of the caterpillar that the caterpillar has when installed on a vehicle.
