Solution Overview

Problem

Traditional methods for upgrading railing systems are aesthetically unpleasing and lack structural integrity, requiring multiple components and exposing fasteners, which can lead to undesirable bending and bowing of deck boards.

Innovation Solution

A railing attachment clip with contoured surfaces that securely attaches a rail topper to a guardrail, providing a snap-fit mechanism that hides screws and enhances structural integrity by lowering the center of gravity, allowing for easy detachment and reattachment without replacing the entire railing system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If traditional screw attachment method is used to attach deck board to rail, then the attachment is simple to implement, but the fasteners are exposed and visible which is aesthetically unpleasing

Engineering Contradiction:
Improveattachment simplicityVSAvoidaesthetic appearance
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

A clip component is introduced as an intermediary between the deck board and rail. The clip has a first portion that attaches to the rail and a second portion that attaches to the deck board, hiding the fasteners within the clip structure and providing a clean aesthetic appearance while maintaining simple attachment through the multi-component design

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If clips are attached to rail and deck board is attached to clips, then the attachment mechanism is established, but the clips have poor structural integrity resulting in waving and bowing of the deck board

Engineering Contradiction:
Improveattachment mechanismVSAvoidstructural integrity
Core Design Contradiction:
Device complexityVSStrength

Solution Approach 1:

The clip design extends vertically with a downwardly extending portion that reaches into the space between the rail and deck board. This vertical extension provides additional attachment points and structural support in the third dimension, preventing waving and bowing by distributing loads more effectively throughout the assembly

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Adaptability or versatility

If multiple components are used to upgrade railing system, then the customization options increase, but the device complexity and number of parts increases

Engineering Contradiction:
Improvecustomization optionsVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The clip is designed as a universal component that can attach to various rail shapes and sizes while maintaining the same basic structure. The contoured first portion can be adapted to different rail profiles, allowing customization of the railing system appearance without requiring multiple different clip designs for different rail types

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

AI summary

A railing attachment clip to couple a guardrail to a rail topper, the clip including left and right portions with respective surfaces contoured to match the guardrail and the rail topper, and a central portion laterally coupled to the left and right portion. The central portion separates the left and right portions by a fixed distance. The matching contoured surfaces determine a position of the railing attachment clip on the guardrail, and determine a position of the rail topper on the railing attachment clip. In some embodiments, the central portion is removed after the railing attachment clip is attached to the guardrail, but before the rail topper is attached to the railing attachment clip.
