Solution Overview

Problem

Existing mobile devices face inconvenience in performing shopping services due to the need for multiple operations to execute payment applications, especially when the device is in a locked or disabled state.

Innovation Solution

A mobile device capable of sensing user gestures on a display unit in a disabled state, enabling the display and executing a wallet application upon matching the gesture with preset information, and facilitating payment through wireless communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the display unit is in a disabled state (locked or off) to enhance security and reduce power consumption, then security and energy efficiency are improved, but the user cannot access payment applications without additional authentication steps

Engineering Contradiction:
ImprovesecurityVSAvoidaccess to payment application
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary authentication by sensing user touch operations on the disabled display unit before enabling access to payment applications. The gesture recognition system is pre-configured with preset gesture information, allowing quick verification without full authentication sequences.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The touch sensor acts as an intermediary between the user and the disabled display unit. By detecting touch operations and comparing them with preset gesture information, the system mediates access control without requiring the display to be enabled, thus maintaining security while enabling convenient access.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If multiple operations are required to execute payment applications on mobile devices, then security and system control are improved, but the shopping service process becomes cumbersome and time-consuming

Engineering Contradiction:
Improvesystem controlVSAvoidtime to complete payment
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system executes the payment application as a preliminary action immediately after recognizing the preset gesture, before the user needs to manually search for or launch the application. This reduces the sequence of operations required while maintaining system control through gesture-based authentication.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system merges the gesture recognition function with the payment application execution function. By combining these operations into a single gesture-triggered sequence, the system reduces the number of separate steps the user must perform while maintaining appropriate security controls.

Inventive Principle:
Principle #5Merging (Combining)

3Ease of operation

If the display unit remains enabled to allow immediate access to applications, then ease of operation is improved, but power consumption increases and security is reduced

Engineering Contradiction:
Improveaccess to applicationVSAvoidpower consumption
Core Design Contradiction:
Ease of operationVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary gesture recognition on the disabled display unit without requiring it to remain enabled. This allows the display to stay in a low-power state while still providing quick access to payment functions through touch-based gesture detection.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The touch sensor system provides self-service by detecting and interpreting user gestures directly on the disabled display surface, eliminating the need for the display unit to be actively enabled for basic interaction. This maintains ease of operation while minimizing power consumption.

Inventive Principle:
Principle #25Self-service

AI summary

A mobile device is provided. The mobile device includes a display unit, a sensor configured to sense user's touch done on a surface of the display unit in a disabled state of the display unit, a storage unit configured to store preset gesture information, a controller configured to enable the display unit when a user's touch operation matched with the gesture information is sensed, execute a wallet application, and display an execution screen, and a communication unit configured to transmit information for a selected payment option to an external apparatus when the payment option is selected on the execution screen and perform a payment. The payment is simply done.
