Mobile Terminal Case with Dual Display and Virtual Gamepad
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile terminals lack the ability to extend their display region and provide a realistic external input device experience without separate peripherals, limiting usability and compatibility with various models.
Innovation Solution
An electronic device comprising a mobile terminal and a case with a first and second wired communication unit, allowing the mobile terminal to control a second display and simulate a gamepad experience through coordinate conversion of touch events, enabling extended display and realistic input without separate hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mobile terminal uses a separate external input device to provide game control functionality, then the sense of realism and operational convenience is improved, but the device complexity and compatibility requirements increase
Solution Approach 1:
The patent combines the input device functionality with the mobile terminal itself by displaying a virtual gamepad overlay on the terminal's display. This merging eliminates the need for separate external input devices while maintaining game control functionality, thereby improving ease of operation without increasing device complexity
Solution Approach 2:
The patent creates a virtual copy of a physical gamepad interface displayed on the mobile terminal screen. This virtual gamepad overlay replicates the functionality and appearance of a physical input device, providing a realistic gaming experience without requiring actual external hardware
2Area of stationary object
If a mobile terminal extends its display region through a case with an additional display, then the display area is increased, but the device complexity and communication requirements increase
Solution Approach 1:
The patent merges the mobile terminal with a protective case that contains an additional display. This combination extends the display area while integrating the case into the functional structure of the terminal, avoiding the need for separate external displays and reducing overall device complexity
Solution Approach 2:
The case serves multiple functions: it protects the mobile terminal and simultaneously extends the display area through its integrated display. This multi-functionality increases the display area without requiring separate dedicated display devices, thereby managing device complexity effectively
3Adaptability or versatility
If wired communication is used between the mobile terminal and case to ensure compatibility without separate chips, then the adaptability is improved, but the device complexity increases due to wiring requirements
Solution Approach 1:
The patent utilizes the existing wired communication interface of the mobile terminal for multiple purposes: its original function and additionally for communicating with the case's display. This universal use of the existing communication path improves compatibility without requiring separate communication chips or additional wiring complexity

AI summary
Provided are a mobile terminal and an electronic device comprising a case to which the mobile terminal is coupled, wherein the mobile terminal comprises: a first wired communication unit provided in a terminal body; and a first display unit coupled to the case, and the case comprises: a first body formed to accommodate at least a portion of the terminal body; a second wired communication unit disposed on one side of the first body; a second body on which a second display unit is disposed; and a wiring unit electrically connecting the first and second bodies. In addition, in an activated state of the first and second display units, a control unit of the mobile terminal displays, on the basis of a touch input applied to any one of the first and second display units, a game pad for playing a game application executed in the mobile terminal on the other display unit. While the game application is being played on the any one of the display units, in response to the occurrence of a first touch event that satisfies a preset condition on the game pad, a second touch event that is coordinate-transformed with respect to the first touch event is generated, and the second touch event is delivered to the game application.
