Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current display apparatuses require numerous key operations and screen changes to switch channels or execute applications, making the process inconvenient and unintuitive for users.
Innovation Solution
A display apparatus and controlling method that utilize four direction keys to display a user interface with channels and applications arranged on axes, allowing users to intuitively navigate and execute applications related to the current channel or similar channels, with features like automatic updating and installation of selected applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional remote control methods are used with up/down keys or EPG for channel switching, then channel selection is possible, but the number of key operations and screen changes increases, reducing ease of operation
Solution Approach 1:
The patent introduces a two-dimensional UI grid layout where channels are arranged horizontally and applications vertically, allowing users to navigate to any channel-application combination using four-directional keys. This dimensional organization eliminates the need for sequential screen changes and multiple key presses, enabling direct access to target content through intuitive directional navigation.
Solution Approach 2:
The four-directional key pad serves multiple functions: navigating between channels, selecting applications, and accessing related content. This multi-functional design replaces the traditional single-function remote control operations, allowing users to perform various tasks (channel switching, application execution, content browsing) through a unified navigation interface, thereby reducing the number of required operations.
2Adaptability or versatility
If additional applications are executed through home hub screen access, then application functionality is available, but the process requires multiple screen changes and key operations, reducing ease of operation
Solution Approach 1:
The patent merges channel selection and application execution into a single unified UI interface. Instead of requiring separate screens for broadcast content and applications, the system combines both functionalities in one grid-based interface where channels and applications coexist and can be accessed through the same four-directional navigation system, simplifying the overall access process.
Solution Approach 2:
The system pre-organizes applications and channels in a structured grid layout before user interaction. Related applications are automatically associated with their corresponding channels and positioned in the UI in advance, so when users navigate to a channel, the related applications are already visible and accessible, eliminating the need for additional screen changes or search operations.
3Ease of operation
If traditional remote control navigation is used, then basic channel switching is possible, but the process is unintuitive and requires numerous operations, reducing ease of operation
Solution Approach 1:
By organizing the interface in two dimensions (channels horizontally, applications vertically) and enabling four-directional navigation, the system allows users to move directly toward target content in any direction rather than following a linear path. This dimensional navigation mirrors natural spatial intuition and significantly reduces the number of steps required to access desired content compared to traditional linear navigation.
