Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing TVs have a fixed screen size that is always exposed, wasting space when not in use and lacking flexibility in displaying content based on user interaction.
Innovation Solution
A TV system with a variable screen size controlled by a motor, incorporating a camera and sensor to adapt the screen exposure and content display to user preferences and location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the entire screen is always exposed, then the display area is maximized, but space utilization deteriorates when the TV is not in use
Solution Approach 1:
The patent implements a motor-driven mechanism that dynamically adjusts the screen exposure between fully exposed, partially exposed, and fully retracted states. This transforms the static screen into a dynamic component that can change its exposure level based on usage conditions, resolving the contradiction between maximizing display area and improving space utilization.
Solution Approach 2:
The screen is divided into multiple exposure levels (fully exposed, partially exposed, fully retracted) that can be independently controlled. This segmentation allows the system to provide different display areas according to different usage scenarios, simultaneously achieving both maximum display area when needed and compact storage when not in use.
2Adaptability or versatility
If a motor is added to control screen exposure, then adaptability is improved, but device complexity increases
Solution Approach 1:
The motor unit serves multiple functions: it controls screen exposure levels, works with the camera to adjust viewing angles, and integrates with the sensor system for automated control. This multi-functionality justifies the added complexity by providing comprehensive adaptability across multiple system components.
Solution Approach 2:
The controller acts as an intermediary that coordinates between the motor, camera, and sensor systems. It processes sensor data, determines appropriate screen exposure levels, and sends control signals to the motor, thereby managing the complexity through centralized control logic rather than distributed complex mechanisms.
3Adaptability or versatility
If the camera angle is fixed, then device complexity is reduced, but adaptability to user location deteriorates
Solution Approach 1:
The sensor detects user presence and location, providing feedback to the controller. The controller then adjusts the camera angle based on this feedback, creating a closed-loop system that automatically adapts to user position. This feedback mechanism enables adaptability without requiring complex manual adjustment mechanisms.
Solution Approach 2:
The camera system automatically adjusts its angle based on sensor input without requiring manual intervention. The system serves itself by using the sensor data to autonomously optimize the camera positioning, reducing the need for complex user interfaces or manual adjustment mechanisms.
4Adaptability or versatility
If the screen size is variable, then space utilization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The system implements discrete screen exposure levels (fully exposed, partially exposed, fully retracted) rather than continuous adjustment. This partial action approach reduces the precision requirements compared to continuous positioning, as the motor only needs to achieve specific predefined positions rather than exact continuous positioning.
