Working Machine Implement Holding and Transport Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current working machines require separate transportation of implements to different locations, which is inconvenient and inefficient, as they need to be manually handled and loaded onto separate transporters.
Innovation Solution
A method and apparatus for a working machine that includes a superstructure rotatable about a first upright axis, with a working arm that can be pivoted and rotated to bring the implement into engagement with a holding device, allowing the implement to be transported while engaged and held, eliminating the need for manual handling and separate transportation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If working implements are transported separately from the machine, then they can be delivered to different locations, but manual handling and loading onto separate transporters is required which is inconvenient and inefficient
Solution Approach 1:
The patent combines the implement holding function with the machine body by providing a holding device mounted on the machine. This merging eliminates the need for separate transporters and manual handling, as implements can be transported while held by the machine itself through coordinated movement of the superstructure and working arm.
Solution Approach 2:
The machine is given multi-functionality by enabling it to both perform working operations with implements and transport implements simultaneously. The holding device and manipulative mechanisms allow the machine to serve dual purposes: working with implements attached to the working arm and transporting implements held by the holding device.
2Productivity
If implements are held by the machine during transport, then manual handling is eliminated, but the machine structure must accommodate additional holding and manipulation mechanisms
Solution Approach 1:
The holding device and manipulative mechanisms serve multiple functions: they hold implements for transport, enable positioning of implements, and work in coordination with the existing working arm system. This multi-functionality justifies the added structural complexity by eliminating separate transport operations.
Solution Approach 2:
The machine performs its own implement transportation function without external assistance. The holding device and manipulative mechanisms enable the machine to autonomously position and transport implements, eliminating the need for manual handling and separate transporter operations.
3Reliability
If the working arm is used to bring implement into engagement with holding device, then implement can be securely held for transport, but additional manipulation steps are required
Solution Approach 1:
The holding device is positioned and prepared in advance on the machine body, ready to receive implements. The manipulative mechanisms are pre-configured to coordinate the working arm's movement, allowing smooth and efficient engagement without repeated adjustments or trial-and-error positioning.
Solution Approach 2:
The system employs coordinated control of the superstructure rotation and working arm manipulation to achieve precise engagement of the implement with the holding device. The interdependent movements provide feedback control, ensuring reliable holding while minimizing unnecessary manipulation time.

AI summary
A method of operating a working machine of the kind including a body, a ground engaging structure, the body carrying a superstructure which is rotatable relative to the body about a first generally upright axis, the superstructure providing a mounting for a working arm which permits the working arm to be pivoted up and down about a generally horizontal axis and to be rotated about a second generally upright axis, the working arm including a mounting structure for releasably carrying at an outermost end thereof, a working implement, the method including providing on the machine a working implement holding device, and rotating the superstructure relative to the body about the first generally upright axis, and manipulating the working arm about the generally horizontal axis and the second generally upright axis to bring the working implement carried by the working arm into holding engagement with the holding device whereby the holding device holds the working implement, releasing the working implement from the mounting structure, and manipulating the working arm to move the mounting structure away from the holding device.
