Remote Operator Seat Layout for Stable Portable Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote operation apparatuses for work machines are heavy and difficult to transport, with poor stability due to high gravity center height and small floor contact area, making them unstable and hard to maneuver.
Innovation Solution
A remote operation apparatus with a modular design, featuring a first housing with a drive device and arithmetic processing units, and a second housing for electronic equipment, where the drive device and processing units are positioned to lower the gravity center and improve balance, and the second housing is lower for easier access and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the housing is made sturdy and large to support the operator and electronic devices, then the structural strength and stability are improved, but the weight increases and transportability deteriorates
Solution Approach 1:
The housing is divided into a first housing for the operator and a second housing for electronic devices. This segmentation allows the total weight to be distributed and managed more effectively, with each housing unit being more manageable for transport while maintaining overall structural strength through their connected design.
2Weight of moving object
If the housing is divided into two small housings to improve transportability, then the weight and size are reduced, but the stability and structural integrity deteriorate
Solution Approach 1:
The first housing and second housing are connected to form an integrated structure. The second housing is positioned to contact and support the first housing, creating a combined stable base that prevents the maneuvering device from falling while maintaining individual housings that are easier to transport separately.
3Ease of operation
If the seat is fixed on a large housing, then the operator comfort is improved, but the gravity center height increases and floor contact area decreases, leading to instability
Solution Approach 1:
The second housing is positioned at a lower height than the first housing, creating a stepped configuration. This dimensional arrangement lowers the overall gravity center of the system while providing a larger effective floor contact area through the combined base of both housings, thereby improving stability without compromising operator comfort in the first housing.
