Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Display devices with small displays face challenges in providing appropriate information and processing operations due to resource constraints, leading to user inconveniences when connected to external devices.
Innovation Solution
A display device with a processor that configures an input list on the screen, allocating areas for various inputs and controlling data reproduction based on predefined orders, allowing easy identification and use of data from connected terminals, including remote controls, AI speakers, and mobile devices, and managing deactivated inputs by turning them on when necessary.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If small display devices are connected to external devices, then display functionality is extended, but resource constraints prevent appropriate information provision and operation processing
Solution Approach 1:
The patent introduces a display device as an intermediary between small display terminals and external devices. The display device receives control signals from small terminals (remote controls, mobile devices) and processes them appropriately, acting as a mediator that bridges the resource constraints of small terminals with the functionality requirements of external devices. This resolves the contradiction by allowing small terminals to extend display functionality while the display device handles the complex information provision and operation processing.
2Adaptability or versatility
If multiple inputs are supported, then input versatility is improved, but identification and management of inputs becomes difficult
Solution Approach 1:
The patent applies visual differentiation (analogous to color changes) by displaying distinct representative images for different input types in the input list. Each input source (HDMI, USB, optical audio) is represented by a unique visual icon or image, making it easy for users to identify and distinguish between multiple connected devices. This resolves the contradiction by maintaining input versatility while simplifying input identification through visual cues.
3Device complexity
If deactivated inputs are ignored, then system complexity is reduced, but user convenience deteriorates when external devices need activation
Solution Approach 1:
The patent implements self-service functionality where the display device automatically detects deactivated inputs and prompts users to activate them. When an external device is connected to a deactivated input, the system automatically generates a notification and guides the user through the activation process without requiring manual configuration. This resolves the contradiction by maintaining low system complexity while improving user convenience through automated assistance.
