Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users struggle to recognize the remaining amount of consumable supplies due to display colors being set independently from background colors, leading to poor visibility when the colors are similar, causing difficulty in distinguishing the remaining amount from the background.

Innovation Solution

A method that calculates the color difference between the remaining amount display color and the background color, and adjusts either the display color or background color to ensure a predetermined threshold difference, improving visibility by altering the brightness in the L*a*b* color space.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the remaining amount display color is set independently from the background color, then the display can be simple and fast, but the visibility of the remaining amount becomes poor when the colors are similar

Engineering Contradiction:

Improvedisplay speedVSAvoidvisibility of remaining amount

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent dynamically adjusts the background color parameter based on the remaining amount display color. When the display color is obtained from the peripheral device, the system calculates a corresponding background color that ensures sufficient color difference, thereby maintaining visibility while preserving display performance

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system incorporates a feedback mechanism where the background color is determined based on the remaining amount display color. This feedback loop ensures that the background color automatically adapts to maintain optimal contrast and visibility without requiring manual intervention

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If the background color is set independently from the remaining amount display color, then the display design is flexible and simple, but the user cannot recognize the remaining amount when colors are similar

Engineering Contradiction:

Improvedisplay design flexibilityVSAvoidinformation recognition

Core Design Contradiction:

Adaptability or versatilityVSLoss of information

Solution Approach 1:

The background color parameter is dynamically changed based on the remaining amount display color. The system calculates an appropriate background color that ensures clear distinction from the display color, preventing information loss while maintaining design flexibility

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces an intermediary color calculation process that bridges the remaining amount display color and the background color. This intermediary mechanism ensures that sufficient color difference is maintained without requiring direct coordination between independent color settings

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

A method for display control is provided. The method includes obtaining information of a remaining amount display color displaying a remaining amount of a consumable supply, obtaining the information of a background color in a displaying area displaying the remaining amount of the consumable supply, and changing a display content in the displaying area on the basis of the remaining amount display color and the background color.
