Sonar Mount Tilt Mechanism for Repeatable Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sonar mounts on boats and ships face challenges in precise and repeatable alignment, particularly when the vessel needs to be trailered or docked, due to the sonar head's projection below the hull, requiring complex recalibration and a 'break away' mechanism to prevent damage from underwater obstructions.
Innovation Solution
A sonar mount with a tilt mechanism that allows the sonar head to be lifted parallel to the deck for trailering, featuring a clamping system with adjustable cross and Z tubes, a breakaway safety mechanism, and a base plate that maintains alignment for easy reinstallation, ensuring precise positioning and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the sonar head is mounted below the waterline for accurate sonar operation, then sonar measurement precision is improved, but the boat cannot be trailered without removing or relocating the sonar head
Solution Approach 1:
The sonar mount incorporates a tilt mechanism that allows the sonar head to be dynamically repositioned between a vertical operating position (extending below the waterline for accurate sonar measurements) and a horizontal storage position (parallel to the deck for trailering). This dynamic adjustment resolves the contradiction by enabling the sonar head to be in the correct position for measurement during operation, yet easily removable or repositionable when trailering is required.
2Measurement precision
If the sonar head is permanently mounted for accurate alignment, then measurement precision is improved, but recalibration is required when the boat is trailered or docked
Solution Approach 1:
The mount includes a base plate with pre-established alignment features and a tilt mechanism that maintains the sonar head's horizontal position relative to the boat deck when tilted. This preliminary setup of alignment references in the base plate ensures that when the sonar head is repositioned via the tilt mechanism, it automatically returns to the correct alignment without requiring time-consuming recalibration procedures.
3Manufacturing precision
If a fixed mounting structure is used for the sonar head, then manufacturing precision is improved, but the sonar head cannot be protected from underwater obstructions
Solution Approach 1:
The tilt mechanism provides a dynamic protection feature where the sonar head can be rotated or tilted to a horizontal position parallel to the deck when the boat is trailered or docked. This dynamic repositioning protects the expensive sonar head from underwater obstructions by removing it from the vulnerable vertical position, while maintaining precise manufacturing and mounting of the mount structure itself.
4Strength
If the sonar head is part of a heavy mounting assembly, then structural strength is improved, but positioning and replacing the sonar head becomes a non-trivial task
Solution Approach 1:
The mounting assembly is segmented into distinct components: a base plate that remains mounted to the boat, a tilt mechanism with rotation capability, and the sonar head unit. This segmentation allows the heavy mounting structure to maintain its strength and stability when installed, while enabling easier positioning and replacement of the sonar head by working with the modular components rather than moving the entire heavy assembly.

AI summary
A sonar mount allows accurate and precise alignment of a sonar head to a boat. A tilt mechanism allows the sonar head to be lifted to a position that is substantially parallel to the boat's deck, thus facilitating placement of the boat on a trailer without the need to remove the sonar head from the boat.
