Mixed-Reality Viewer for Lifting Vehicle Operator Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lifting vehicles face challenges in providing the operator with a complete and unobstructed view of the surrounding environment, especially when external objects or vehicle parts obstruct the view, making it difficult to maneuver and manage loads safely and stably.
Innovation Solution
A multifunctional lifting vehicle equipped with a vision system comprising cameras and distance detection devices, coupled with a mixed-reality viewer device of the head-up display type with video pass-through, which generates a mixed-reality visualization of the environment to assist the operator in real-time driving and load management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the operator controls the vehicle from inside the driving cab or remotely, then the vehicle can be operated, but the view is obstructed by objects that interpose themselves along the field of vision, making it difficult to maneuver and manage loads safely
Solution Approach 1:
The patent introduces a camera system as an intermediary device that captures visual information from the environment and transmits it to the operator. The camera is positioned to obtain a view that is not obstructed by the vehicle structure, acting as a mediator between the operator and the external environment, thereby compensating for the blocked field of vision without requiring the operator to physically relocate.
Solution Approach 2:
The patent creates a visual copy of the external environment by using a camera to capture images and transmitting them to a display device. This copy of the visual scene allows the operator to perceive the environment as if directly observing it, bypassing the physical obstructions caused by the vehicle cab and enabling safe maneuvering without direct line of sight.
2Stability of the object's composition
If external objects or vehicle parts obstruct the view, then the vehicle structure remains intact, but the operator cannot see the surrounding environment completely, generating difficulties in maneuvering
Solution Approach 1:
The camera system serves as an intermediary that bridges the gap between the vehicle's fixed structure and the operator's need for unobstructed vision. By positioning the camera externally where it has a clear view, the system mediates the conflict between maintaining structural integrity and enabling operational visibility, allowing the vehicle to remain structurally sound while providing the operator with an unobstructed visual feed.

AI summary
A multifunctional lifting vehicle includes: a base frame, a lifting assembly including an operating arm equipped with an attachment for mounting a tool, a control system of the lifting assembly, having an electronic control unit and sensors arranged to acquire vehicle stability data, including a position of the arm with respect to the frame and an amount of load lifted by the tool, a vision system mounted on the frame, having a camera to acquire images and detect events occurring outside the vehicle, and a detection device to measure an object's distance outside the vehicle, detected by the camera, and a mixed-reality viewing device of a head-up display type with video, operationally connected to the control unit for generating, on the basis of data acquired by the vision system, three-dimensional information on the surrounding environment which assists in driving and managing the lifted load.
