Handheld Game Console Dual Screen Nesting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable handheld game devices lack dual screen functionality combined with touch-sensitive technology and the ability to accommodate different-sized game cards in a user-friendly console configuration.
Innovation Solution
A portable handheld game device with a unique console configuration featuring twin backlit LCD screens, one of which is touch-sensitive, and a design that allows for easy access to various features, including a pivotable cover body, multiple control buttons, and slots for different-sized game cards, along with a hardware/software system capable of displaying different three-dimensional images on two display units using a single three-dimensional image processing unit without causing flicker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If dual screen functionality is added to portable game devices, then display capability and interactive experience are improved, but device complexity increases
Solution Approach 1:
The patent implements dual screen functionality by nesting one display within the cover body and another within the main body, allowing both screens to be housed within the compact portable console structure. The screens are positioned to overlay each other when closed, providing dual display capability without significantly increasing external dimensions.
Solution Approach 2:
The game console is designed with multi-functional slots that can accommodate different-sized game cards (both Game Boy Advance and Game Boy Color formats), allowing the device to serve multiple gaming purposes. The cover body itself serves dual purposes as both protective closure and as a housing for the second display screen.
2Ease of operation
If touch-sensitive technology is integrated into the display, then user interaction is improved, but manufacturing complexity increases
Solution Approach 1:
The patent combines the touch-sensitive display technology with the existing LCD screen structure, integrating the touch sensitivity layer directly into the display assembly. This merging approach allows touch functionality to be added without requiring separate control mechanisms or additional user interface components.
3Adaptability or versatility
If the console is designed to accommodate different-sized game cards, then adaptability is improved, but slot design complexity increases
Solution Approach 1:
The patent implements a dynamic slot design where the cover body can pivot between open and closed positions, allowing access to different card slots. The slot configuration adapts to different card sizes through the mechanical movement of the cover, which reveals different insertion points for Game Boy Advance versus Game Boy Color cards.
Solution Approach 2:
The game card slots are designed with asymmetric characteristics to accommodate different card formats. The slots have distinct geometric features and orientations that naturally guide the correct insertion of specifically sized cards, preventing incompatible cards from being inserted while maintaining support for multiple card types.
4Illumination intensity
If three-dimensional images are displayed on two screens simultaneously, then visual experience is improved, but image processing complexity increases
Solution Approach 1:
The patent employs periodic action in the image processing by alternating the display of three-dimensional images between the two screens in sequential frames. This frame-by-frame alternating display approach allows a single three-dimensional image processing unit to generate images for both screens without requiring simultaneous processing, thereby reducing computational complexity while maintaining the visual effect of dual 3D display.

AI summary
A portable, handheld game console includes a main body incorporating a first display screen, and a cover body incorporating a second display screen. The main body is hingedly connected to the cover body along adjacent forward and rearward edges, respectively, such that the cover body is movable between a closed and open positions. The main body is provided with a plurality of control buttons and a pair of game card slots for receiving game cards of different dimensions. One of the game cards is substantially square and comprises a substantially flat card body having a plurality of electrically conductive terminal strips adjacent the forward edge. One of the side edges of the card has a single continuous step configuration along substantially the entire length dimension of the card. A first notch is formed in a first forward corner of the card where the forward edge meets the other of the pair of side edges and a second notch is formed along the other of the pair of side edges, between the forward and rearward edges.
