Rotary Control Element for Dynamic Region Marking on Vehicle Navigation Maps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle navigation systems are not user-friendly for marking regions on road maps displayed on vehicle video screens, as they require prolonged interaction and inconvenient correction of map detail size and position, making it difficult to efficiently navigate around specific areas.
Innovation Solution
A system that allows selecting and fixing a region on a vehicle's video screen using a control element, which can be rotated and moved to change the region's size and position, enabling easy and rapid marking and integration into the navigation system, even when the vehicle is within the marked area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional drawing device is used to mark regions on the road map, then the region can be marked, but the system requires prolonged interaction and is not user-friendly for comfort-optimized vehicles
Solution Approach 1:
The patent changes the operational parameters of the control element from conventional multi-step operations to simple rotational movement. By rotating the control element, the boundary of the marked region is dynamically adjusted, allowing rapid size changes without requiring multiple operations. This parameter change approach enables the region marking to be completed quickly and easily, resolving the contradiction between ease of operation and time consumption.
2Adaptability or versatility
If the map detail size and position are changed for correction, then the region can be adjusted, but the operation becomes inconvenient and time-consuming
Solution Approach 1:
The patent merges the functions of map detail size adjustment and region marking into a single control element operation. The same control element that marks the region also adjusts its size and position through rotational movement. This merging of functions allows simultaneous adjustment of multiple parameters (region size, position, and map detail) through one unified operation, making the correction process convenient and efficient.
Solution Approach 2:
The patent introduces dynamic adjustment capability where the control element can be rotated during the marking process to continuously adjust the region size and position. This dynamic approach allows real-time corrections without requiring separate static adjustment steps, enabling users to adapt the region boundaries flexibly while maintaining ease of operation throughout the process.
3Measurement precision
If multiple control operations are required for region marking, then precise control is achieved, but the system complexity increases
Solution Approach 1:
The patent designs the control element to perform multiple functions: marking the region, adjusting region size, changing map detail size, and positioning the map detail. This universal control element eliminates the need for separate control devices for each function, reducing overall system complexity while maintaining precise control capabilities through its multi-functional design.

AI summary
In the case of a system for marking a region within an image of a road map detail displayed on a vehicle video screen, a regional location can first be selected by a control element. The region, which represents one of several administrative levels, can be constantly fixed via an enter function of the control element. The administrative level and thereby the size of the region can be changed by a rotational movement of the control element, which can be rotated about a longitudinal axis.
