Solution Overview

Problem

Existing support systems for carrying watercraft and recreational equipment on vehicles often fail to provide sufficient contact and protection, leading to 'hot spots' of pressure that can cause damage due to the curved nature of watercraft hulls and differences in hull shapes.

Innovation Solution

The support pads and adjustable supports feature a base layer, contact layer, and ribs that define hollow cells, allowing for three-dimensional movement and independent cell movement to conform to various shapes, along with rotatable arms for customizable support and cushioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If a rigid support structure is used, then structural strength is improved, but contact adaptability to curved watercraft hulls deteriorates

Engineering Contradiction:
Improvestructural strengthVSAvoidcontact adaptability
Core Design Contradiction:
StrengthVSAdaptability or versatility

Solution Approach 1:

The support pad is divided into multiple independent hollow cells that can move and deform independently. Each cell acts as a separate support element, allowing the pad to conform to curved surfaces while maintaining overall structural integrity through the collective action of all cells.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support pad uses a flexible cellular structure with hollow cells that can deform and flex to adapt to the curved geometry of watercraft hulls. This flexible cellular design allows the rigid-looking pad to actually conform to various hull shapes while maintaining strength.

Inventive Principle:
Principle #30Flexible shells and thin films

2Ease of manufacture

If a single solid support pad is used, then manufacturing simplicity is improved, but pressure distribution deteriorates

Engineering Contradiction:
Improvemanufacturing simplicityVSAvoidpressure distribution
Core Design Contradiction:
Ease of manufactureVSStress or pressure

Solution Approach 1:

The pad is segmented into multiple hollow cells that can independently deform to distribute pressure evenly across the contact surface. This segmentation prevents pressure hot spots by allowing localized compression in each cell while maintaining support across the entire pad area.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hollow cellular structure functions similarly to porous materials, providing multiple voids that can compress and deform to distribute applied loads. This cellular architecture allows the pad to conform to pressure variations in the load while maintaining manufacturing simplicity through integral molding.

Inventive Principle:
Principle #31Porous materials

3Adaptability or versatility

If the support pad structure is made complex to adapt to different shapes, then adaptability is improved, but device complexity increases

Engineering Contradiction:
Improveshape adaptabilityVSAvoidstructural complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The base layer, contact layer, and ribs are merged into a single integral structure that is molded as one piece. This combining of multiple functional elements into a unified cellular structure achieves shape adaptability without requiring separate components, fasteners, or complex assembly procedures.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hollow cellular structure serves multiple functions simultaneously: it provides structural support, distributes pressure, adapts to various shapes, and absorbs shocks. This multi-functionality is achieved through a single cellular design that eliminates the need for separate components for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)
