Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If HMI applications are developed to conform to open platforms for handheld terminals, then the applications have general versatility and information freshness, but the applications cannot be directly introduced into the vehicular navigation apparatus for operation
Solution Approach 1:
The patent creates a universal platform layer that enables HMI applications developed for open platforms to run on vehicular navigation apparatus. The control device includes a platform that can operate both dedicated vehicular applications and general-purpose HMI applications, allowing the system to accept applications from multiple sources without individual development for each vehicle system.
Solution Approach 2:
The patent introduces a management device as an intermediary between the HMI applications and the control device. This management device acquires attribute information of the HMI applications and notifies the control device, enabling seamless integration without requiring modifications to the original applications. The intermediary handles the compatibility layer that allows external applications to operate in the vehicular environment.
2Adaptability or versatility
If externally-introduced HMI applications are allowed to operate, then information freshness and versatility improve, but UI output conflicts arise with ready-made vehicular applications
Solution Approach 1:
The patent implements dynamic UI output switching where the control device can selectively switch between UI output from dedicated vehicular applications and UI output from HMI applications based on operational conditions. The system dynamically determines which application's UI output to display based on the current vehicle state and application attributes, preventing conflicts while maintaining both types of applications.
Solution Approach 2:
The management device acquires and manages attribute information of HMI applications, including parameters that define when and how UI output should be displayed. By changing and managing these parameters dynamically, the system can coordinate UI output from multiple applications without conflicts, allowing HMI applications to provide fresh information while maintaining reliable UI coordination.
3Reliability
If individual set-up is provided for externally-introduced HMI applications, then operational requirements are met, but considerable development resources are needed
Solution Approach 1:
The management device automatically acquires attribute information of HMI applications and configures them for operation without requiring manual individual set-up. The system self-services by automatically managing the integration parameters and operational requirements compliance, eliminating the need for considerable development resources while ensuring reliable operation.
4Reliability
If dedicated applications are operated independently, then vehicle-specific functions are ensured, but platform compatibility and application versatility are limited
Solution Approach 1:
The patent segments the application execution environment into two independent parts: a platform layer that handles general-purpose HMI applications and a dedicated application layer that handles vehicle-specific functions. This segmentation allows both dedicated applications and platform applications to operate independently without interfering with each other, ensuring vehicle-specific reliability while enabling platform compatibility.
Data Source
AI summary
A vehicular navigation apparatus configured to independently operate a dedicated application and an externally-introduced general-purpose application is provided. The navigation apparatus includes a control device and a management device. The management device notifies the control device of attribute information of the general-purpose application in operation. Based on the attribute information, the control device determines whether the general-purpose application operating under a specified condition is allowed to use user interface output under the specified condition. When no user interface output is allowed as a result of the determination, the control device switches over the user interface output to user interface output using another certified general-purpose application.
