Solution Overview

Problem

Existing projection systems lack efficient control mechanisms for projecting operation images to facilitate user interaction within a defined projection range, often relying on explicit user instructions for image positioning.

Innovation Solution

A control device and method that utilize a processor to project an operation image within a projection range based on second information indicating the positional relationship between the projection apparatus and the projection range, allowing for automatic determination and maintenance of the image position without explicit user guidance.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the operation image is projected to a fixed position in the projection range, then the projection system is simple to control, but the user interaction efficiency deteriorates when the user moves to different locations

Engineering Contradiction:

Improveuser interaction efficiencyVSAvoidcontrol mechanism complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The projection apparatus detects the user's position within the projection range and uses this feedback information to automatically adjust the projection position of the operation image, ensuring the image remains accessible to the user regardless of their location

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system transitions from a static fixed-position projection to a dynamic adaptive projection system that automatically adjusts the operation image position based on real-time user position detection, making the system responsive to user movement

Inventive Principle:

Principle #15Dynamics

2Productivity

If the operation image position is manually adjusted by user instructions, then the projection system maintains simplicity, but the operation time increases due to explicit user guidance requirements

Engineering Contradiction:

Improveoperation speedVSAvoidtime for explicit user instructions

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The projection apparatus automatically determines and adjusts the operation image projection position based on detected user position information, eliminating the need for users to provide explicit instructions and thereby reducing operation time

Inventive Principle:

Principle #25Self-service

3Ease of operation

If the operation image is projected away from the user for safety or space reasons, then the projection apparatus can operate in constrained environments, but the ease of operation deteriorates

Engineering Contradiction:

Improveoperation intuitivenessVSAvoidenvironmental adaptability

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The system dynamically changes the projection position parameter of the operation image based on the user's detected position, allowing the image to be projected at varying distances and locations within the projection range to optimize both user interaction and environmental constraints

Inventive Principle:

Principle #35Parameter changes

AI summary

A control device of a projection apparatus that projects an image to a projection target object, includes a processor, and the processor is configured to, in response to reception of a first operation by an operation portion for operating the projection apparatus, perform a control of projecting an operation image for operation of the projection apparatus from the projection apparatus to a part, in a projection range of the projection apparatus, determined based on second information different from first information obtained by the first operation performed on the operation portion
