Marine Propulsion Pivot Joint Harness Routing for Flexible Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Propulsion systems for marine vessels face challenges in guiding harnesses without damaging them due to the complexity and movement of components, leading to risks of damage from moving parts.
Innovation Solution
A propulsion system design featuring a transom bracket connected to the marine vessel with a drive unit via a first pivot joint, allowing the harness to be guided through this joint, optionally with a connecting arm and additional pivot joints, providing movement freedom and protection to the harness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the propulsion system is made movable in relation to the marine vessel to provide flexibility and adjustability, then the adaptability is improved, but the risk of harness damage increases due to movement of parts
Solution Approach 1:
A pivot joint is introduced as an intermediary component between the movable propulsion system and the fixed marine vessel. This pivot joint serves as a mediator that allows controlled movement while guiding and protecting the harness, preventing direct contact between moving parts and the harness, thus resolving the contradiction between flexibility and harness integrity.
2Reliability
If the propulsion system components are made complex to provide guiding paths for harnesses, then the harness protection is improved, but the device complexity increases
Solution Approach 1:
The pivot joint is designed to serve multiple functions simultaneously: it acts as a rotational connection for the movable propulsion system, provides a guiding path for the harness, and protects the harness from damage. By making this single component multi-functional, the patent avoids increasing overall system complexity while still achieving comprehensive harness protection.
