Solution Overview

Problem

Existing image processing systems are affected by the influence of light emission from placement units during document imaging, which can interfere with the imaging process and user interaction.

Innovation Solution

An image processing apparatus with a placement unit, imaging unit, and light emitting device, controlled by a processor to manage light emission based on the presence or absence of a document, including conditions such as power state and user authentication, to minimize interference and enhance user interaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the light emitting device causes the placement unit to emit light to prompt document placement, then user interaction is improved, but imaging quality deteriorates due to light interference

Engineering Contradiction:
Improveuser interactionVSAvoidimaging quality
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The light emitting device dynamically changes its emission state based on operational context. The processor controls the device to emit light during user interaction phases (when no document is detected) and to cease emission during imaging phases (when a document is detected), creating a dynamic adaptation that resolves the contradiction between user guidance and imaging quality

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The light emitting device operates in periodic cycles: emitting light to prompt document placement, then stopping emission when imaging is required. This periodic on-off operation allows the system to alternate between enhancing user interaction and ensuring imaging quality, with the processor managing the timing transitions between these states

Inventive Principle:
Principle #19Periodic action

2Ease of operation

If the light emitting device emits light continuously to guide users, then ease of operation is improved, but energy consumption increases

Engineering Contradiction:
Improveuser guidanceVSAvoidenergy consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system employs periodic action by controlling the light emitting device to emit light only during specific periods when user guidance is needed (when no document is present on the placement unit). During imaging periods and other operational phases, the device remains off, thereby significantly reducing energy consumption while maintaining effective user guidance when required

Inventive Principle:
Principle #19Periodic action

Solution Approach 2:

The processor automatically detects whether a document is present on the placement unit and autonomously controls the light emitting device accordingly. This self-service mechanism eliminates the need for continuous light emission by having the system independently determine when user guidance is necessary, thus reducing energy consumption while maintaining ease of operation

Inventive Principle:
Principle #25Self-service
