Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing decking system railings are labor-intensive to assemble due to the need to align holes in the mounting piece with the frame, especially when the deck is high off the ground, requiring time-consuming and labor-intensive processes.

Innovation Solution

A platform system with interlock couplings and a locking mechanism, where the railing system slides into channels in the header frame, supported by interlock couplings that prevent pivoting and a locking pin that prevents vertical movement, simplifying the attachment process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If railings are attached using bolted mounting pieces with hole alignment, then the connection is secure and reliable, but the assembly process becomes time-consuming and labor-intensive

Engineering Contradiction:

Improveconnection reliabilityVSAvoidassembly efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The mounting piece is divided into separate components: a base portion that attaches to the frame and a top portion that forms the railing support. This segmentation allows each component to be independently positioned and secured, eliminating the need for precise hole alignment while maintaining connection reliability through the interlocking channel design

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The channel structure acts as an intermediary element between the mounting piece and the frame. The tongue of the mounting piece fits into the channel of the frame, providing a guided interface that automatically aligns components during assembly without requiring manual hole matching, thus improving assembly efficiency while maintaining secure connection

Inventive Principle:

Principle #24Intermediary (Mediator)

2Manufacturing precision

If traditional hole alignment method is used for mounting railings, then precise positioning can be achieved, but the assembly process requires significant time and labor

Engineering Contradiction:

Improvepositioning accuracyVSAvoidassembly time

Core Design Contradiction:

Manufacturing precisionVSLoss of time

Solution Approach 1:

The channel and tongue structures are pre-formed during manufacturing with precise dimensions and tolerances. This preliminary precision work eliminates the need for time-consuming field alignment operations, as the components are designed to fit together automatically with the correct positioning upon assembly

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of aligning holes through manual positioning, the design inverts the approach by using a positive-fit tongue-and-channel mechanism where the protruding tongue automatically guides and positions the mounting piece within the channel, achieving precise positioning through the shape complementarity rather than hole alignment

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A platform system includes a platform frame having a header defining a first channel. Decking is mounted to the platform frame. A post is attached to a mounting member, which defines a second channel. The mounting member and the header form an interlock coupling where a portion of the mounting member resides in the first channel and a portion of the header resides in the second channel. A locking pin is positioned within a recess that is partially defined by the header and that is partially defined by the mounting member to limit movement of the mounting member relative to the header.
