Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Users of portable terminal devices face difficulties in remembering the correspondence between operation scenes and gestures, leading to impaired operability when trying to return the touch panel to a normal state from a halt state.

Innovation Solution

A portable terminal with a display module that displays a home screen including icons, where a lock state can be set, and a lock screen is produced with a corresponding cancellation icon, allowing users to perform operations by touching the cancellation icon, thereby improving user operability.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple operation scenes and gestures are registered, then the functionality and versatility of the portable terminal is improved, but the complexity of remembering and operating increases

Engineering Contradiction:

Improveoperation scene functionalityVSAvoidgesture memorization burden

Core Design Contradiction:

Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent creates a copy of the home screen interface elements (icons, layout) and places them on the lock screen. This allows users to interact with familiar visual elements on the lock screen to cancel the locked state, eliminating the need to remember complex gesture sequences while maintaining the security function of the lock screen.

Inventive Principle:

Principle #26Copying

Solution Approach 2:

The patent introduces an intermediary mechanism where touching icon elements on the lock screen serves as a mediator to cancel the locked state. This intermediary interaction simplifies the user operation from complex gesture sequences to simple icon touching, while still achieving the desired function of accessing the home screen.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If the touch panel is returned to normal state from halt state using gestures, then the operational responsiveness is improved, but the risk of unintentional inputs increases

Engineering Contradiction:

Improveoperational responsivenessVSAvoidunintentional input risk

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies local quality by making specific icon elements on the lock screen interactable for cancellation purposes, while other areas remain restricted. This localized interactivity allows intentional cancellation operations without exposing the entire interface to unintentional activation, improving both responsiveness and reliability.

Inventive Principle:

Principle #3Local quality

AI summary

A mobile phone 10 comprises a display 14 and a touch panel 16, and a lock state of restricting performance of the predetermined processing based on a touch operation is set. A home screen including a function icon is displayed on the display 14. When the lock state is set, a lock screen is produced based on this home screen. Then, the lock screen is displayed if the power supply of the display 14 is turned on. A cancellation icon corresponding to the function icon is included in the lock screen. If a cancellation operation using the cancellation icon corresponding to a mail application is performed the lock state is canceled and the mail application is performed.
