Reconfigurable Wind Gauge Display for Vessel Orientation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional close hauled wind gauges have difficulty distinguishing between heading upwind or downwind due to indicator needle behavior and lack of practicality for vessels with varying ideal wind angles, as they typically display only a zoomed-in view of 20-60 degrees off the bow and stern, making it hard to determine the vessel's orientation and requiring a zigzag pattern for maximum speed.
Innovation Solution
A reconfigurable display system that adjusts visual representations of wind gauges based on wind angle ranges, allowing users to specify display settings, with a control device coupled with wind angle and speed sensors to position the wind speed indicator differently depending on the wind angle, enabling multiple visual representations for improved usability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a close hauled wind gauge displays a zoomed-in view of 20-60 degrees off the bow and stern, then the precision of wind angle measurement is improved for optimal sailing, but the ability to determine vessel orientation (upwind vs downwind) deteriorates
Solution Approach 1:
The display dynamically changes its presentation based on the current wind angle range. When the vessel is sailing close-hauled (20-60 degrees), the gauge provides magnified precision for that range. When the vessel is on a different course, the display automatically adjusts to show the appropriate zoom level and angle range, ensuring both precision and orientation information are always available.
Solution Approach 2:
The system adds a temporal dimension to the display by automatically switching between different zoom levels and angle ranges based on the current sailing conditions. This allows the same physical display to present multiple scales and perspectives of wind angle data, resolving the contradiction between precision and orientation information.
2Measurement precision
If a close hauled wind gauge displays only 180 degrees (0-90 degrees port and starboard), then the precision for close-hauled sailing is improved, but the adaptability to different vessel designs and sailing conditions deteriorates
Solution Approach 1:
The display is designed to dynamically adjust its angle range and zoom level based on the current sailing conditions and vessel characteristics. Different vessel types with different ideal wind angles can have their specific ranges configured and displayed, making the system adaptable to various sailboat designs while maintaining precision for each vessel's optimal performance range.
Solution Approach 2:
The wind gauge is designed as a universal instrument that can serve multiple sailing conditions and vessel types. By incorporating automatic range detection and display adjustment, the same device can optimize for close-hauled sailing, running sails, or other configurations depending on what the current situation requires.
3Measurement precision
If the indicator needle holds at maximum scale values for extended angle ranges (60-120 degrees and 240-300 degrees), then the precision for optimal wind angles is maintained, but the ease of operation and interpretation deteriorates
Solution Approach 1:
The indicator needle behavior is dynamically adjusted based on the current wind angle. Instead of holding static at maximum values, the needle continuously updates to reflect the current angle relative to the optimal range, providing both precision for optimal angles and ease of interpretation for all sailing conditions.
Solution Approach 2:
The display provides continuous feedback to the helmsman about the current wind angle and its relationship to the optimal range. By showing whether the vessel is too high, too low, or perfectly aligned with the ideal wind angle, the system maintains precision while improving ease of operation through intuitive visual feedback.

AI summary
A wind gauge display apparatus comprising a control device and a reconfigurable display for displaying a first visual representation of a wind gauge if a wind angle is within a first range and displaying a second visual representation of the wind gauge if the wind angle is within a second range. The angles displayed on the reconfigurable display may be determined by input from a user. On the reconfigurable display, a location of a visual indicator of wind speed may be different in the first visual representation of the wind gauge than in the second visual representation of the wind gauge. The wind gauge display apparatus may also comprise a sensor for determining wind angle and wind speed.
