Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern vehicle systems in motor vehicles are complex and require extensive user interaction, making it difficult for users to learn and operate them without extensive explanatory information, which is often provided in printed manuals that users are reluctant to read.
Innovation Solution
A vehicle system that includes an interface for detecting control inputs and a control device for controlling functionalities, with a storage medium for explanation information, allowing the system to operate in various modes such as assistance, instruction, and explanation modes, providing feedback and multimodal output of information to support user learning and operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If printed operating manuals are provided to explain vehicle system functionalities, then users can obtain explanation information, but users are reluctant to read them and learning effectiveness is poor
Solution Approach 1:
The patent replaces the mechanical system of printed manuals with an electronic information output system that delivers explanation information through the vehicle's existing interface (display screens, speakers). This substitution transforms static text into dynamic, context-aware multimedia explanations that are delivered automatically based on detected control inputs, making information delivery more engaging and effective while maintaining the ability to provide comprehensive operational guidance.
Solution Approach 2:
The system implements feedback by detecting control inputs (user actions on controls) and automatically providing relevant explanation information in response. This closed-loop approach ensures that explanation information is delivered precisely when needed during operation, creating an interactive learning experience that adapts to the user's actual operational needs rather than requiring proactive reading of manuals.
2Adaptability or versatility
If vehicle systems provide multiple functionalities with complex operation steps, then system capabilities are enhanced, but explaining these operations becomes difficult in printed manuals
Solution Approach 1:
The system dynamically adapts the delivery of explanation information based on the detected control inputs and current operational context. Rather than providing static, pre-written manual content, the system generates and delivers context-relevant explanations in real-time during operation, making it feasible to explain complex multi-step procedures by breaking them down into context-aware, step-by-step guidance.
Solution Approach 2:
The system segments complex operational procedures into discrete, context-specific explanation units that are delivered in response to specific control inputs. This segmentation allows complex multi-functionality to be explained through a series of simple, context-relevant steps rather than overwhelming the user with comprehensive manual text, thereby managing explanation complexity while maintaining system versatility.
3Loss of information
If electronic operating manuals are provided to support user learning, then information accessibility is improved, but optimal learning support is not achieved
Solution Approach 1:
The system performs preliminary action by detecting control inputs in advance and preparing relevant explanation information before the user actually needs it. This proactive approach ensures that explanation information is already available and delivered at the precise moment when the user encounters a control or operational step, optimizing learning support rather than merely providing accessible but untimed information.
Solution Approach 2:
The system uses feedback from detected control inputs to automatically trigger and deliver context-relevant explanation information. This feedback-driven approach transforms static electronic manuals into an interactive learning system that adapts to user behavior, providing optimal learning support by delivering information precisely when and how it is needed during actual operation.

AI summary
The vehicle system, controlled by control inputs, provides functionalities in the motor vehicle (1) and has an interface (9) for acquiring the control inputs and outputting data as well as a control device (5) for controlling the functionalities in accordance with the acquired control inputs. A storage medium (7) on which instructions explaining the functionalities and/or operation are stored is linked to the control device (5). The control device (5) is designed to retrieve instructions from the storage medium (7) and output the same as part of the instructions via the interface (9). The vehicle system (3, 3′) can be operated in an assistance mode in which the user inputs are interpreted and evaluated as control inputs for the functionalities while instructions explaining the respective activated functionality and/or other operational options are additionally output at the same time.
