Solution Overview

Problem

Existing watercraft accessory mounting systems lack adjustable positioning and orientation options, limiting the flexibility and security of accessories like fishing rod holders and cup holders on cylindrical side rails.

Innovation Solution

A tubular handrail with a multi-faceted profile and a clamping system that provides incremental adjustability and secure attachment, preventing rotation and allowing for various accessory orientations by interlocking with the rail's facets.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a cylindrical rail is used, then the rail has a simple manufacturing process and smooth exterior, but the mounting system lacks rotational adjustment capability and positioning precision

Engineering Contradiction:
Improverail manufacturing simplicityVSAvoidmounting adjustment capability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent applies asymmetry by transitioning from a symmetric cylindrical rail to an asymmetric multi-faceted rail profile. The rail features flat surfaces at specific angular intervals (e.g., 0°, 45°, 90°, 135°) that break the rotational symmetry of a cylinder. This asymmetric geometry enables the clamping system to engage at discrete angular positions, providing rotational adjustment capability while maintaining a relatively simple extrusion manufacturing process for the rail profile.

Inventive Principle:
Principle #4Asymmetry

Solution Approach 2:

The patent applies segmentation by dividing the continuous rotational adjustment into discrete angular increments defined by the flat surfaces on the rail. Instead of allowing continuous rotation, the multi-faceted profile creates distinct engagement positions (e.g., every 45 degrees for an 8-facet rail). This segmentation provides precise positioning while simplifying the clamping mechanism design, as the clamp only needs to engage with these predefined surfaces rather than provide continuous angular control.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If a clamping system is designed to allow continuous rotation, then the accessory positioning flexibility is maximized, but the system becomes complex and difficult to control

Engineering Contradiction:
Improveaccessory positioning flexibilityVSAvoidclamping system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies dynamics by designing a clamping system that transitions from a fixed positional state to a dynamically adjustable state with discrete angular positions. The clamp can be rotated along the rail to different angular positions defined by the flat surfaces, providing flexibility while maintaining control. The system is dynamic in that it allows movement between predefined positions rather than being fixed at a single location.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The patent applies parameter changes by modifying the angular position parameter of the mounted accessory. Instead of allowing continuous angular adjustment, the system changes the angular position in discrete increments determined by the rail's flat surfaces. This parameter discretization provides sufficient positioning flexibility for various accessory orientations while simplifying the control mechanism, as users only need to select from predefined angular positions rather than control continuous rotation.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If mounting positions are fixed, then the system structure is simple and robust, but the adaptability to different accessory orientations is limited

Engineering Contradiction:
Improvesystem structural simplicityVSAvoidaccessory orientation options
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent applies universality by designing a multi-functional rail system that serves both as a structural support element and as an angular positioning mechanism. The multi-faceted profile of the rail provides multiple engagement surfaces that enable the same rail structure to accommodate accessories at various orientations (e.g., 0°, 45°, 90°, 135°). This universal design allows a single rail configuration to fulfill multiple mounting orientation requirements without needing separate mounting structures for each angle.

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