Vehicle Menu Display Decoupling Selection From Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing menu display and operating devices in vehicles limit user freedom in selecting multiple functions simultaneously, often requiring sequential decision-making without full context, leading to premature and potentially incorrect choices.
Innovation Solution
A display and operating device that displays all menu functions simultaneously on a screen, allowing partial function preselection with a pushbutton-rotary switch, decoupling selection from activation, and providing visual emphasis for clarity and correction opportunities, with automatic preselection based on vehicle states and conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all menu functions are displayed simultaneously on the screen, then the user has complete overview and can make informed decisions, but the device complexity increases compared to sequential display methods
Solution Approach 1:
The menu functions are segmented into individual display elements that can be independently selected and highlighted. Each function appears as a separate item on the screen that can be individually preselected, allowing the user to view and choose multiple functions without overwhelming the display system.
Solution Approach 2:
The patent introduces a temporal dimension to the selection process by decoupling preselection from activation. Users can preselect multiple functions across different time points, and the system manages these selections in a separate state before final activation, reducing the instantaneous complexity of the display system.
2Adaptability or versatility
If the user can preselect multiple functions simultaneously, then the freedom of choice increases, but the operation complexity increases compared to single function selection
Solution Approach 1:
The system performs preliminary action by allowing users to preselect multiple functions before final activation. The preselection state stores the user's choices without immediately executing them, enabling flexible modification of the selection before commitment. This separates the selection process from the activation process, making operations easier.
Solution Approach 2:
The system provides visual feedback by displaying which functions are currently preselected on the screen. This feedback mechanism helps users track their selections and make informed decisions about which functions to activate, reducing operational complexity through clear system-state communication.
3Reliability
If the selection process is decoupled from activation, then the user can correct mistakes before execution, but the operating time increases compared to immediate activation
Solution Approach 1:
The system performs preliminary selection actions without immediate activation, creating a buffer state where selections can be reviewed and corrected. This preliminary phase separates the selection decision from the activation execution, allowing error correction without significantly extending the overall operating time since activation occurs promptly after confirmation.

AI summary
In a display and operating device for the functions of a menu, which includes multiple functions, in a vehicle having a screen display and input device for preselection of a function by dialing a respective screen symbol, all the functions of the menu may be displayed simultaneously on the screen display and may be preselected individually in a visually discernible manner by the input device. The preselected functions are jointly activatable in response to a switch command.
