Content Presentation Arbitration With Standby and Cancellation Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing content presentation systems in vehicles face challenges in dynamically managing content arbitration, leading to interruptions and inappropriate information delivery due to fixed settings for content that loses arbitration, which complicates maintainability and user experience.
Innovation Solution
A presentation control device that stores rule definitions with attributes and constraint expressions to freely change the setting of content that loses arbitration, allowing for dynamic prioritization based on the winning content, thereby avoiding maintainability reduction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed settings are used for content that loses arbitration, then system simplicity is maintained, but adaptability and user experience deteriorate due to inappropriate information delivery
Solution Approach 1:
The patent implements dynamic arbitration rules that automatically adjust the handling of defeated content based on the type of winning content. When navigation content wins arbitration, defeated content is set to standby; when other content wins, defeated content is canceled. This dynamic adaptation resolves the contradiction by making the system flexible without requiring complex manual configuration.
Solution Approach 2:
The system changes the state parameter of defeated content (between 'standby' and 'canceled') based on the arbitration outcome. This parameter change mechanism allows the system to adapt to different scenarios automatically, improving versatility while maintaining manageable complexity through rule-based control.
2Adaptability or versatility
If complex arbitration rules are implemented to improve content management flexibility, then adaptability improves, but maintainability deteriorates
Solution Approach 1:
The arbitration system is segmented into distinct components: arbitration rules, content attributes, and execution logic. This segmentation allows each component to be independently maintained and modified, improving maintainability while preserving flexibility. The rule definition storage unit separates configuration from execution, enabling easier updates.
Solution Approach 2:
The system uses self-descriptive content attributes that automatically determine arbitration outcomes without requiring external configuration. Content items carry their own priority and type information, enabling the arbitration unit to make decisions autonomously based on predefined rules, reducing maintenance burden.
3Ease of operation
If dynamic content arbitration is implemented, then user experience improves through appropriate information delivery, but interruptions occur due to frequent content switching
Solution Approach 1:
The system performs preliminary classification of content types and pre-defines arbitration rules before conflicts occur. By establishing the arbitration framework in advance with clear rules about when to use standby versus cancel, the system minimizes decision-making delays and reduces interruptions during actual content switching.
Solution Approach 2:
The standby state mechanism allows defeated content to remain available for quick resumption without complete interruption. When navigation content (which requires continuous attention) wins arbitration, other content goes to standby rather than being fully canceled, enabling seamless transitions and maintaining continuity of useful actions.

AI summary
In a presentation control, another presentation request of another content is accepted from another application while presenting a content of one application, which content is preferentially presented is arbitrated based on a rule definition including: an attribute of the content that defines either a cancellation for withdrawing the presentation request or an on-standby without withdrawing the presentation request; and a constraint equation that defines an exception rule for defining a setting of the content that has lost arbitration as either the on-standby or the cancellation; and one of the contents arbitrated is presented to a presentation area.
