Solution Overview

Problem

Current ballast systems in wakeboats are inefficient in filling, moving, and draining water, leading to slow weight adjustments, increased risk during emergencies, and high electrical demands, which pose safety and operational challenges.

Innovation Solution

Implementing direct drive ballast pumps that mechanically couple to the engine using belt/chain or hydraulic systems to directly transfer power, eliminating intermediate electrical conversions and allowing for faster and more efficient ballast operations without requiring hull motion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electrically powered ballast pumps are used, then the system can operate independently of hull motion, but the electrical load increases and response speed decreases

Engineering Contradiction:

Core Design Contradiction:

Ease of operationVSUse of energy by moving object

Solution Approach 1:

The patent replaces the electrical pump system with a mechanically driven ballast pump system. The mechanical system uses the boat's existing mechanical power (engine or propeller shaft) to directly drive the ballast pumps, eliminating the need for electrical conversions and reducing electrical load while maintaining operational independence from hull motion.

Inventive Principle:

Solution Approach 1:

The mechanical drive system provides more immediate power transmission compared to electrical systems. By directly coupling the ballast pumps to the mechanical power source, the system eliminates electrical conversion delays and provides faster response times during emergency ballasting operations.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If intermediate electrical conversions are used, then the system design is simpler, but power transfer efficiency decreases

Engineering Contradiction:

Core Design Contradiction:

Device complexityVSLoss of energy

Solution Approach 1:

The patent eliminates intermediate electrical conversions by using a direct mechanical drive system. This removes energy losses associated with electrical-to-mechanical conversion while maintaining manageable system complexity through direct power transmission from the existing mechanical power source to the ballast pumps.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

4Loss of energy

If mechanical direct drive systems are implemented, then power transfer efficiency increases, but the device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The patent leverages the boat's existing mechanical power transmission infrastructure (engine mounting, propeller shaft, accessory drive belts) to power the ballast pumps. This approach achieves high power transfer efficiency by using direct mechanical coupling while avoiding the need for complex dedicated mechanical drive systems, as the power transmission path already exists in the boat's propulsion system.
