Solution Overview

Problem

Existing television remote controllers with densely packed buttons are difficult to navigate in dark environments, especially for users with poor eyesight or the elderly.

Innovation Solution

A remote controller equipped with an image signal acquisition unit, control unit, and sending unit to detect the position of a user's finger on the operating surface and send this information to a display terminal, allowing the user to view the corresponding button position on a display screen, even in low light conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If buttons are densely distributed on the remote controller, then the remote controller can provide more control functions, but it becomes difficult for users to quickly find the desired button in dark environments

Engineering Contradiction:
Improvecontrol functionsVSAvoidbutton finding difficulty
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent introduces a display terminal as an intermediary device that receives finger position information from the remote controller and displays the corresponding button position and function information. This mediator bridges the gap between the user's finger and the actual button, allowing users to see what button they are pressing without needing to visually locate the button on the remote itself.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback by displaying real-time information about which button is being pressed on the display terminal. The display shows the button position and function information based on finger position detection, providing immediate feedback to the user about their input, which helps users understand which button they are operating even in dark environments.

Inventive Principle:
Principle #23Feedback

2Adaptability or versatility

If buttons are densely distributed on the remote controller, then more control functions are available, but the complexity of the operating surface increases

Engineering Contradiction:
Improvecontrol functionsVSAvoidoperating surface complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent moves the complexity visualization from the two-dimensional remote controller surface to the display terminal screen. By projecting button position and function information onto a separate display dimension, the system allows the remote controller to maintain a compact, dense button layout while the display terminal handles the presentation of complex information in a larger, more readable format.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Device complexity

If the remote controller uses traditional button design, then the structure is simple, but users with poor eyesight or the elderly have difficulty finding buttons in dark environments

Engineering Contradiction:
ImprovestructureVSAvoidbutton finding difficulty
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The display terminal serves as an intermediary that compensates for the limitations of simple button design. While the remote controller maintains its simple structure, the display terminal provides visual assistance by showing users which button is being pressed, effectively bridging the gap between simple hardware design and user accessibility needs.

Inventive Principle:
Principle #24Intermediary (Mediator)
