Solution Overview

Problem

The increasing complexity of mobile communication terminals, such as cellular phones, necessitates a more complex input unit to perform various functions, which often requires a larger space, compromising user convenience.

Innovation Solution

A media reproducing apparatus with a touch wheel configured as a touch panel that includes multiple functions, allowing users to perform drag operations on specific regions to execute functions like jog and shuttle without extending the device's area, utilizing a control unit to differentiate between start points and output audio signals for function identification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple input units are installed to perform various functions, then function versatility is improved, but device area increases

Engineering Contradiction:
Improvefunction versatilityVSAvoiddevice area
Core Design Contradiction:
Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The touch wheel button unit is designed to perform multiple functions including jog function (drag operation), shuttle function (touch and hold for predetermined time), and channel selection function (circumferential direction drag). By integrating these diverse functions into a single input unit, the patent achieves multi-functionality without increasing device area, directly resolving the technical contradiction between function versatility and device area.

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

2Adaptability or versatility

If the touch panel area is extended to provide additional functions, then function versatility is improved, but device complexity increases

Engineering Contradiction:
Improvefunction versatilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The touch wheel button unit is segmented into multiple functional regions including a first region for jog function, a second region for shuttle function, and a third region for channel selection. This segmentation allows different functions to be implemented within a compact area by dividing the input unit into distinct operational zones, achieving function versatility without increasing overall device complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The touch wheel button unit employs dynamic operation modes where the same physical region can perform different functions based on touch duration and pattern. For example, a short touch performs channel selection while a touch held for a predetermined time performs shuttle function. This dynamic behavior enables multiple functions within a single static structure, avoiding the need for additional physical components.

Inventive Principle:
Principle #15Dynamics

AI summary

A media reproducing apparatus may include a main body; a touch wheel button unit disposed in a region of the main body; and a control unit configured to perform a first function in response to receiving a first drag operation in a circumferential direction while a first start point disposed in the touch wheel button unit is touched, and perform a second function in response to receiving a second drag operation in the circumferential direction while a second start point, which is different from the first start point, is touched. The media reproducing apparatus may also include the region of the main body configured as a touch panel.
