Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing jack plates for outboard boat motors do not provide a hydraulic tilt and trim functionality, limiting the ability to efficiently adjust the motor's position.
Innovation Solution
A hydraulic tilt and trim device comprising a transom portion, motor portion, hydraulic cylinder, and electric hydraulic pump, allowing for the hydraulic tilting and trimming of the jack plate by pivoting the motor portion relative to the transom portion using a hydraulic cylinder and ram system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional jack plate is used for mounting an outboard motor, then the motor can be positioned vertically, but the motor cannot be tilted or trimmed hydraulically
Solution Approach 1:
The patent combines multiple functions (mounting, tilting, and trimming) into a single integrated device. The jack plate structure is merged with hydraulic tilt and trim mechanisms, allowing the motor to be mounted, tilted, and trimmed using one unified system rather than separate components.
Solution Approach 2:
The jack plate is designed to perform multiple functions: it serves as both a mounting structure and a tilting/trimming mechanism. The hydraulic cylinder and pivot bracket assembly enables the same structure to adjust motor angle (tilt) and vertical position (trim), making the device universal for various positioning needs.
2Productivity
If manual adjustment methods are used for motor positioning, then the device structure remains simple, but the operational efficiency and precision are reduced
Solution Approach 1:
The patent replaces manual mechanical adjustment with a hydraulic system. Instead of using hand-operated mechanisms or simple linkages, the invention employs hydraulic cylinders actuated by an electric pump, substituting manual mechanical systems with automated hydraulic-mechanical systems for faster and more precise adjustment.
Solution Approach 2:
The invention uses hydraulic principles to achieve motor positioning. A hydraulic cylinder connected to the pivot bracket provides controlled movement for tilting and trimming the motor, utilizing fluid pressure to generate the necessary force and motion for efficient adjustment.
3Adaptability or versatility
If hydraulic components are added to enable tilting and trimming, then operational flexibility is enhanced, but manufacturing costs may increase
Solution Approach 1:
The hydraulic system is divided into separate modular components: a hydraulic cylinder for tilt/trim actuation, a pivot bracket for mechanical linkage, and an electric pump for fluid pressurization. This segmentation allows each component to be manufactured independently using standard parts, simplifying production and reducing overall manufacturing complexity despite adding functionality.
