Projection Guidance Device for Warehouse Operator Error Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators at product delivery centers face challenges in accurately performing operations without error, as they often work in complex environments with multiple objects and locations, and head-mount displays can be burdensome.
Innovation Solution
A guidance control device that communicates with a projection device to generate and project subject-identifying and guide images on specific ranges, allowing operators to identify their tasks and follow instructions without the need for display devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a head-mount display is used to display guidance information, then operators can receive guidance information without using traditional display devices, but the operator bears a burden of load
Solution Approach 1:
The patent introduces a projection device as an intermediary to deliver guidance information. Instead of directly placing a display device on the operator's head, the system projects guidance information onto the floor or surrounding environment, allowing the operator to view it naturally without wearing any additional equipment, thus eliminating the weight burden while maintaining guidance functionality
Solution Approach 2:
The patent replaces the mechanical head-mount display system with an optical projection system. Instead of using a physical display device that must be worn by the operator, the system uses light projection to display guidance information in the operator's field of view, substituting a mechanical burden with a non-contact optical method
2Productivity
If multiple operators work at proximate positions in a complicated positional relationship, then productivity increases, but errors in operations occur
Solution Approach 1:
The patent applies local quality by projecting guidance information specifically at each operator's working position and orientation. The projection system adjusts the content and position of guidance information based on each operator's location, ensuring that each operator receives personalized guidance tailored to their specific task and spatial context, thereby maintaining high accuracy even when multiple operators work closely together
Solution Approach 2:
The patent implements dynamics by making the projection system adaptive to real-time changes in operator positions and orientations. The system continuously updates the projected guidance information based on the current spatial configuration of operators and objects, allowing the guidance to dynamically adjust as operators move and reposition themselves during high-speed operations

AI summary
A guidance control device is configured to control a projection device for projecting images. The guidance control device is configured to generate a subject-identifying image to be projected on a first projection range relating to a first position at which a subject person conducts a predetermined operation and to generate a guide image guiding the predetermined operation for the subject person to be projected on a second projection range relating to a second position viewable by the subject person. Accordingly, the guidance control device is able to control the projection device including the subject-identifying image and the guide image.
