Forklift Automation Unit Layout That Preserves Operator Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing forklift trucks lack sufficient space for integrating all necessary devices for automated operation without obstructing the operator's view or requiring a dedicated counterweight, which increases manufacturing costs.
Innovation Solution
An automated operation unit is integrated into the vehicle body, specifically positioned at a height equal to or lower than the operator's view, using an accommodation case that includes devices like an automated operation controller, display, and emergency stop, with a displacement mechanism to avoid obstruction during manned operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If devices for automated operation are installed in the head guard, then automated operation functionality is achieved, but the operator's view is obstructed
Solution Approach 1:
The accommodation case is positioned at the rear of the vehicle body instead of the front head guard, utilizing the rear spatial dimension. This relocates the automated operation devices from the front view-blocking area to the rear area, eliminating view obstruction while maintaining automation functionality.
2Area of stationary object
If devices for automated operation are installed at high positions, then space utilization is improved, but maintenance work becomes difficult
Solution Approach 1:
The accommodation case is designed with a specific height range (0.8m to 1.5m from the ground) that optimizes local spatial utilization in the rear area while ensuring accessibility for maintenance personnel. This localized quality control resolves the conflict between space utilization and maintenance accessibility.
3Extent of automation
If a dedicated counterweight is provided to accommodate devices, then automated operation functionality is achieved, but manufacturing costs increase
Solution Approach 1:
The accommodation case serves multiple functions: it houses automated operation devices, maintains vehicle balance without requiring a dedicated counterweight, and utilizes existing rear space. This multi-functionality eliminates the need for additional dedicated counterweight structures, reducing manufacturing costs.
4Volume of stationary object
If space is maximized for automated operation devices, then automation capability is improved, but operator's view is obstructed
Solution Approach 1:
The solution utilizes the rear vertical and horizontal space dimensions of the vehicle body, positioning the accommodation case in the rear area. This dimensional relocation allows maximum device accommodation space without interfering with the operator's forward view during manned operation.

AI summary
An industrial vehicle capable of manned travel and unmanned travel by the automated operation includes a vehicle body; and an automated operation unit that is mounted on the vehicle body and in which a plurality of devices for automated operation is integrated. The plurality of devices includes: an automated operation controller controlling the automated operation; a display device on which information related to the automated operation is displayed; an input device on which data related to the automated operation is input; and an emergency stop device causing an emergency stop of the automated operation. The automated operation unit includes an accommodation case accommodating the automated operation controller, the display device, the input device, and the emergency stop device. The accommodation case is positioned in the vehicle body at a height equal to or lower than a height that does not obstruct an operator's view during the manned travel.
