Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle devices have limited display and input capabilities, making it difficult to effectively display and operate content-related information due to size constraints.
Innovation Solution
An information processing apparatus and method that links multiple devices, allowing the acquisition and control of application information through a communication block, enabling enhanced display on a secondary device with a larger display block, such as a smartphone, to present more detailed and quantity-rich information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the display size of the in-vehicle apparatus is increased to show more information, then the quantity and detail of displayed information is improved, but the device size and installation space requirements increase
Solution Approach 1:
The patent extends the display dimension from the in-vehicle apparatus to the user's portable terminal device. By transmitting display data through communication interfaces and rendering it on the terminal's screen, the system effectively adds a spatial dimension to the display capability, allowing full-information presentation without increasing the physical footprint of the in-vehicle device.
Solution Approach 2:
The portable terminal device serves as an intermediary between the in-vehicle apparatus and the user. It receives display data via communication blocks, processes the information, and presents it on its own display screen, thereby mediating the information transfer and eliminating the need for a large onboard display.
2Ease of operation
If the input device size is increased to improve operability, then the ease of operation is improved, but the device complexity and installation constraints are worsened
Solution Approach 1:
The portable terminal device acts as an intermediary for input operations. It receives input signals from the user through its own input interfaces (touchscreen, keyboard, etc.), transmits these signals to the in-vehicle apparatus via communication blocks, and relays the results back to the user, thereby providing enhanced operability without adding complex input hardware to the in-vehicle system.
Solution Approach 2:
The portable terminal device performs multiple functions: it serves as both the input device and the display device for the in-vehicle apparatus. By leveraging the terminal's existing input and display capabilities, the system avoids the need for separate dedicated input and display hardware in the vehicle, reducing overall complexity.
3Adaptability or versatility
If the in-vehicle display is made compact to meet installation constraints, then the installation flexibility is improved, but the display capability and information presentation are worsened
Solution Approach 1:
The system compensates for the small in-vehicle display by adding a second display dimension through the portable terminal device. The terminal receives and displays copies of the same information, effectively doubling the display availability without requiring the in-vehicle display to be larger, thus maintaining installation flexibility while preserving information display capability.
