Crane Camera Display With Assistance Graphics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Crane operators often require additional support staff to direct them during loading and unloading operations, as existing systems lack adequate assistance for orienting the load suspension apparatus and gripping tools effectively, especially when handling semi-trailers and containers.
Innovation Solution
The integration of assistance graphics onto the camera display screen, allowing the crane driver to visually align the load suspension apparatus and gripping tools with the load, eliminating the need for additional support staff by providing a visual aid for precise orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If cameras are installed to provide visual feedback to the crane driver, then the orientation capability is improved, but additional support staff are still required to direct the crane driver
Solution Approach 1:
The patent implements a feedback mechanism by superimposing assistance graphics (such as target indicators, alignment lines, or virtual guides) directly onto the camera image displayed on the screen. This provides the crane driver with real-time visual feedback about the precise orientation and position of the load suspension apparatus relative to the target load, enabling self-correction without external assistance.
Solution Approach 2:
The assistance graphic acts as an intermediary between the camera system and the crane driver. Instead of providing raw camera images alone, the system processes the visual information and adds interpretive graphical elements that guide the driver's actions, bridging the gap between visual data and operational decisions.
2Measurement precision
If multiple cameras and processing systems are added to provide assistance graphics, then orientation accuracy is improved, but device complexity increases
Solution Approach 1:
The control stand serves multiple functions: it houses the camera system, processes images, generates assistance graphics, displays visual feedback, and provides the operational interface for the crane driver. By consolidating these functions into a single integrated unit, the system achieves high orientation accuracy without proportionally increasing overall system complexity.
Solution Approach 2:
The patent merges the camera system, image processing unit, graphic generation software, and display screen into an integrated control stand. This consolidation allows the system to deliver sophisticated orientation assistance while maintaining a compact and manageable structure, avoiding the need for separate distributed systems.

AI summary
A crane with at least one main carrier which is moveable and a crane trolley which is mounted on the at least one main carrier for movement, a winch carrier being fastened to the crane trolley, and a load suspension apparatus which is moveable up and down in the vertical direction by cables hanging on the winch carrier, the load suspension apparatus having gripping tools for releasably gripping a load. The crane has at least one camera and at least one control stand for a crane driver, and the control stand has at least one screen. At least one assistance graphic can be superimposed on the at least one screen onto the display of the image recorded instantaneously by the camera, as an aid for the crane driver for orienting the load suspension apparatus and/or the gripping tool of the load suspension apparatus relative to the load to be gripped.
