Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing earth working machines face challenges in quickly and easily replacing the working apparatus without incurring significant installation moment loads on the drive configuration, leading to complex and labor-intensive installation processes.
Innovation Solution
Incorporating an actuator on the drive configuration that can move the working apparatus from a preparation position to the operating position, reducing or eliminating installation moment loads by shortening the load arm and allowing efficient force application to bring the working apparatus closer to its operational position.

Engineering Contradiction Analysis
1Productivity
If the working apparatus is manually positioned and installed on the drive configuration, then installation flexibility is maintained, but installation time increases and labor intensity increases
Solution Approach 1:
The actuator system enables the working apparatus to be positioned and installed automatically without manual intervention. The actuator member, which is part of the drive configuration, autonomously conveys the working apparatus from preparation position to operating position, making the installation process self-service and eliminating the need for manual positioning operations.
Solution Approach 2:
Manual mechanical positioning operations are replaced by an automated actuator mechanism. The actuator uses controlled mechanical movement (likely hydraulic or electric) to convey the working apparatus axially from preparation to operating position, substituting manual labor with an automated mechanical system that reduces both time and effort.
2Ease of operation
If the actuator is positioned far from the working apparatus during installation, then easier access is achieved, but installation moment loads increase
Solution Approach 1:
The actuator member is designed to move dynamically between different positions during the installation process. It can extend to reach the working apparatus when needed, then retract to a position that minimizes moment loads on the drive configuration. This dynamic positioning allows the actuator to maintain both accessibility and mechanical advantage throughout the installation sequence.
Solution Approach 2:
The actuator performs preliminary positioning actions before final installation. It first conveys the working apparatus axially to the preparation position where alignment can be achieved, then makes final adjustments to bring it into the operating position. This staged approach allows the actuator to work from advantageous positions that reduce moment loads while maintaining accessibility.
