Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle interaction methods are cumbersome and inefficient, particularly for rear occupants, due to limited and complicated operation devices, and existing IoV applications do not effectively facilitate interaction with individual output devices in dynamic scenarios like vehicles.
Innovation Solution
A method using ultra-wideband positioning and attitude sensing to determine the position and orientation of a user terminal device within a vehicle, enabling intuitive interaction with specific output devices through simple operations such as tapping, gestures, or movement, allowing data communication between the device and the vehicle to facilitate seamless interaction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple output devices are provided for each occupant, then entertainment and comfort are improved, but device complexity and operation difficulty increase
Solution Approach 1:
The patent introduces a user terminal device (smartphone, tablet, or wearable device) as an intermediary between the occupant and the vehicle's output devices. The terminal device runs an application that communicates with the vehicle's head unit, enabling the occupant to control multiple output devices through a single, familiar interface rather than directly interacting with each device. This mediator approach resolves the contradiction by maintaining high adaptability while reducing operational complexity.
Solution Approach 2:
The application on the user terminal device provides universal control capabilities for multiple types of output devices (displays, speakers, ambient lighting) through a single interface. Rather than requiring separate control mechanisms for each output device, the application offers multi-functional control that adapts to different device types and occupant positions, thereby improving versatility without increasing device complexity.
2Device complexity
If operation devices are concentrated and limited in number, then device simplicity is maintained, but interaction effectiveness for rear occupants deteriorates
Solution Approach 1:
The patent leverages the three-dimensional spatial environment within the vehicle by using the user terminal device's position and orientation data to determine which output device the occupant intends to control. Instead of requiring multiple physical control devices distributed throughout the vehicle, the system adds a spatial dimension to the interaction model, allowing rear occupants to easily select and control output devices based on their terminal device's pointing direction, thereby improving ease of operation without increasing device quantity.
3Adaptability or versatility
If IoV applications provide bidirectional control between smartphone and vehicle, then connectivity is improved, but operation complexity increases
Solution Approach 1:
The application implements self-service functionality by automatically determining the occupant's intended output device based on the terminal device's position and orientation, and by automatically establishing communication with the vehicle's head unit. Rather than requiring the user to manually configure connections or navigate complex settings, the system performs these tasks autonomously, thereby maintaining bidirectional control capability while improving operational simplicity.
4Adaptability or versatility
If control interfaces are comprehensive and functional, then device control capability is improved, but user interaction smoothness deteriorates
Solution Approach 1:
The system performs preliminary actions by pre-establishing communication channels between the user terminal device and the vehicle's head unit, and by pre-determining the mapping between terminal device orientation and target output devices. This preparation work is done automatically before the user needs to interact with specific output devices, allowing for smooth, intuitive control without requiring users to navigate complex interfaces or perform setup procedures, thereby maintaining comprehensive control capability while improving interaction smoothness.
