Solution Overview

Problem

Traditional display apparatuses with external input devices lack intuitive and dynamic control mechanisms for managing multiple content images, such as resizing, positioning, and aspect ratio adjustments, which are cumbersome and inefficient for users.

Innovation Solution

A display apparatus equipped with a control knob and four-directional keys on an external input device that allows for dynamic control of content images on the display, including resizing, positioning, and aspect ratio adjustments through user inputs on the control knob and directional keys.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If traditional external input devices with basic direction keys are used, then device simplicity is maintained, but control functionality for managing multiple content images becomes insufficient

Engineering Contradiction:

Improvecontrol functionalityVSAvoidinput device structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The external input device integrates multiple control mechanisms (control knob, directional keys, touch pad) into a single universal remote controller that can perform various functions including resizing, positioning, and aspect ratio adjustment of content images, eliminating the need for separate control devices for each function

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The control knob and directional keys are arranged in a nested configuration where the control knob is positioned at the center surrounded by the four-directional keys, creating a compact integrated control structure that maximizes functionality within a small form factor

Inventive Principle:

Principle #7Nested doll (Nesting)

2Measurement precision

If manual resizing and positioning of content images is implemented, then control precision is improved, but user operation time and complexity increase

Engineering Contradiction:

Improveimage positioning precisionVSAvoidoperation time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system automatically detects and processes user intent from control knob rotation direction and magnitude, pre-calculating the required image resizing and positioning parameters before execution, which eliminates the need for users to manually adjust each parameter step-by-step

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The display shows real-time feedback of control knob rotation and current image size/position parameters, allowing users to monitor adjustments as they occur and make precise corrections if needed, reducing the time required to achieve desired positioning precision

Inventive Principle:

Principle #23Feedback

3Quantity of substance

If multiple content images are displayed simultaneously, then information presentation capability is enhanced, but image overlap and disorganization occur

Engineering Contradiction:

Improvenumber of content imagesVSAvoidimage layout organization

Core Design Contradiction:

Quantity of substanceVSStability of the object's composition

Solution Approach 1:

The system dynamically adjusts the positions and sizes of multiple content images based on real-time user input from the control knob and directional keys, allowing images to be repositioned and rescaled on-the-fly to maintain an organized layout even as the number of displayed images changes

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

Each content image can be independently positioned and sized with different parameters, allowing the system to optimize the layout of each individual image while maintaining overall organizational stability across multiple simultaneous displays

Inventive Principle:

Principle #3Local quality

4Measurement precision

If control knob rotation display is added to show rotation and size changes, then user feedback and control precision are improved, but display information complexity increases

Engineering Contradiction:

Improvecontrol feedback precisionVSAvoiddisplay information structure

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The display information is segmented into distinct visual elements: control knob rotation indication, current image size parameters, and position coordinates, allowing users to process each type of information separately rather than overwhelming them with undifferentiated data

Inventive Principle:

Principle #1Segmentation

AI summary

A display apparatus includes a display; a receiver configured to receive a signal from an external input device including a control knob; at least one memory storing instructions; and at least one processor electrically connected to the display and the receiver, and which executes the stored instructions. The at least one processor displays a first content image on the display, display a rotation of the control knob of the external input device and a size of the first content image on the display based on the received signal corresponding to a user input which is input through the external input device, and change a size of the first content image and display the changed size of the first content image on the display, based on at the received signal corresponding to the rotation of the control knob of the external input device.
