Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recreational vehicles have an increasing number of functions controlled by separate devices, leading to complexity and user inconvenience.
Innovation Solution
A circular-shaped user input element on a touchscreen for controlling multiple functions of a recreational vehicle, allowing user inputs through movement and tactile feedback, with wireless or wired signal transmission to processors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate control devices are used to control different functions, then each function can be controlled independently and reliably, but the number of control devices increases leading to complexity and user inconvenience
Solution Approach 1:
The patent combines multiple separate control devices into a single touchscreen interface. The circular-shaped user input element integrates control capabilities for HVAC, lighting, entertainment, and other vehicle functions into one unified interface, eliminating the need for multiple separate physical controls while maintaining reliable control over each function.
Solution Approach 2:
The touchscreen interface with the circular input element serves as a universal control device that can handle multiple different functions. By detecting different movement patterns (rotational direction, speed, distance) along the circular element, the system provides multi-functional control through a single device, reducing overall system complexity.
2Ease of operation
If a touchscreen interface with circular input element is used, then the number of control devices is reduced and user-friendliness is improved, but tactile feedback and precision control may be compromised compared to physical controls
Solution Approach 1:
The system incorporates feedback mechanisms in the touchscreen interface to provide users with confirmation of their inputs. The circular-shaped user input element detects movement patterns and provides visual feedback on the touchscreen, allowing users to see their selections and adjustments in real-time, which compensates for the lack of physical tactile feedback.
Solution Approach 2:
The circular-shaped user input element uses a curved geometric form that is intuitive and easy to interact with. The circular shape naturally guides user movement and allows for rotational input, making the interface more user-friendly while maintaining simplicity despite the sophisticated detection capabilities required.

AI summary
The present disclosure generally relates to a method implemented in a Recreational Vehicle User Interface (RVUI) and a corresponding RVUI for controlling one or several functions of a recreational vehicle (RV). A circular-shaped user input element is displayed at a touchscreen of the RVUI. Furthermore, a user input is detected at the touchscreen of the RVUI. This user input comprises a movement along the displayed circular-shaped user input element. The movement is indicative of a request to control a user-selected function of the recreational vehicle. The user-selected function includes any one or a combination of: a climate control function, a heater function, a ventilation function, a water heater function, a vehicle battery function, a light control function, and a security alarm function. Responsive to detecting this user input, control of the user-selected function is initiated, or otherwise triggered.
