Solution Overview

Problem

Launching a kayak from a dock in deep water is challenging due to stability issues, requiring a second person or difficult balancing acts, especially for individuals with disabilities or limited mobility.

Innovation Solution

A dock-mounted kayak launching system with a submersible kayak rack that stabilizes the kayak using supporting arms, allowing for easy embarkation and disembarkation, and includes a lever mechanism for raising and lowering the rack between submerged and raised states.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a kayak is launched from deep water, then the kayak can be launched from a dock, but the stability is lost making it difficult to embark

Engineering Contradiction:
Improveease of embarkationVSAvoidstability
Core Design Contradiction:
Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent introduces a dock-mounted support structure with supporting arms as an intermediary between the kayak and the deep water. This support structure provides a stable platform for the kayak during embarkation, eliminating the instability of deep water while maintaining the ability to launch from a dock. The support arms hold the kayak in a elevated position, creating a stable intermediate state during the embarkation process.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If a second person pushes the kayak out, then the kayak can be launched, but an additional person is required

Engineering Contradiction:
Improvesolo launch capabilityVSAvoidlaunch system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The dock-mounted support structure enables solo kayak launch by providing self-service functionality. The support structure automatically holds and positions the kayak in the water, allowing the kayaker to embark independently without requiring assistance from a second person. The system serves itself by maintaining the kayak in a ready-to-launch position through the mechanical support of the arms.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If the supporting arms are raised for storage, then the kayak can be stored out of water, but the mechanism complexity increases

Engineering Contradiction:
Improvestorage capabilityVSAvoidmechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The supporting arms are designed with dynamic characteristics, allowing them to be adjusted between different positions. The arms can be lowered to support the kayak during launch and raised to elevate the kayak for storage out of the water. This dynamic adjustability provides versatility for both launch and storage functions while using a relatively simple mechanical linkage system connected to the dock mount.

Inventive Principle:
Principle #15Dynamics

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

The system provides stable kayak support akin to shallow water conditions, enabling solo kayak launching and storage, while accommodating varying water heights and ensuring ease of use for individuals with mobility limitations.

Implementation Method 1

A dock-mounted support for the kayak that stabilizes the kayak on supporting arms while the individual embarks

Methodology Applied
Scientific EffectBuoyancy: Archimedes' Principle (Buoyancy)
