Solution Overview

Problem

Conventional portable terminals with touch screen panels require multiple keys for standard operations, making them impractical for small-size designs like watch phones, and are prone to inadvertent inputs and wrong operations during idle mode.

Innovation Solution

A watch phone with a touch screen panel and a single mode selection key that turns the panel off in watch mode and on in idle mode or upon incoming calls, displaying two areas for call connection or rejection, allowing users to connect or reject calls by pointing or dragging on these areas.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple keys are provided for standard operations on a portable terminal with touch screen panel, then call management functions are complete, but device complexity increases and small-size design becomes impractical

Engineering Contradiction:
Improvecall management functionVSAvoidnumber of keys
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch screen panel is designed to perform multiple functions: it serves as both the display interface and the input interface for call management. The single key also performs multiple roles including mode selection and call acceptance/rejection when combined with touch screen interactions, eliminating the need for separate dedicated keys for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent combines the functions of multiple separate keys into a single physical key配合touch screen panel. The single key merged with the touch screen interface provides mode selection, call acceptance, and call rejection capabilities that traditionally required separate dedicated keys, thereby reducing device complexity while maintaining full call management functionality.

Inventive Principle:
Principle #5Merging (Combining)

2Ease of operation

If touch screen panel is kept on during idle mode to enable immediate input, then ease of operation improves, but inadvertent inputs increase

Engineering Contradiction:
Improveimmediate input capabilityVSAvoidinadvertent input
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary actions by displaying visual indicators on the touch screen panel that guide users on how to properly interact with incoming calls. The panel shows directional arrows or highlighted areas indicating the correct touch zones for acceptance or rejection, preventing inadvertent inputs while maintaining readiness for immediate operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The touch screen panel acts as an intermediary between the user and the call management functions. It provides visual feedback and directional guidance that mediates the interaction, ensuring users intentionally activate the correct functions rather than accidentally triggering them, thus reducing inadvertent inputs while keeping the interface responsive.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If touch screen panel is kept off during idle mode to prevent inadvertent inputs, then reliability improves, but automatic activation may still cause wrong operations

Engineering Contradiction:
Improveinadvertent input preventionVSAvoidautomatic activation accuracy
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

Before automatic activation occurs, the system prepares the touch screen panel by displaying visual indicators that show the correct interaction method for incoming calls. This preliminary visual guidance ensures that when the panel activates automatically, the user can immediately understand how to proceed, preventing wrong operations while maintaining reliability.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The touch screen panel provides visual feedback by displaying directional arrows, highlighted zones, or icons that indicate the correct touch areas for call acceptance or rejection. This feedback mechanism guides users during automatic activation, ensuring they perform the intended action rather than making wrong operations, thus resolving the contradiction between reliability and ease of operation.

Inventive Principle:
Principle #23Feedback

AI summary

A watch phone and a method for handling an incoming call using the watch phone are provided. In the watch phone, a display device includes a touch screen panel and a display, turns off the touch screen panel in a watch mode, turns on the touch screen panel in an idle mode or upon receipt of an incoming call, and displays at least two areas for call connection and call rejection, upon receipt of the incoming call. A single mode selection key selects one of the watch mode and the idle mode. A controller performs control operations so that the touch screen panel is turned off in the watch mode and is turned on in the idle mode or upon receipt of the incoming call, and connects or rejects the incoming call, when the at least two areas for call connection or call rejection, which are displayed upon receipt of the incoming call, are pointed to or dragged to.
