Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing scaffolding boards are difficult to stack efficiently due to protruding stoppers, leading to increased volume and weight, and are prone to displacement during transport, especially when exposed to weather conditions, which affects their handling and security.

Innovation Solution

The scaffolding board features recesses on its top side to receive stop limits, allowing for closer stacking and reduced volume, with stop limits and recesses designed to minimize displacement, and can be made from lightweight materials like aluminum or carbon fiber to maintain strength while reducing weight, and includes grips and aperture patterns for easier handling and water drainage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If scaffolding boards are provided with protruding stoppers to prevent displacement, then displacement is limited, but stacking volume increases and boards cannot be stacked closely

Engineering Contradiction:

Improvedisplacement preventionVSAvoidstacking volume

Core Design Contradiction:

Stability of the object's compositionVSVolume of moving object

Solution Approach 1:

The patent inverts the conventional design by moving the stopper function from the underside to the top side of the scaffolding board. The recesses are provided at the top side instead of protruding stoppers at the underside, allowing boards to stack closely while still preventing displacement through the interaction of recesses and stop limits.

Inventive Principle:

Principle #13The other way round (Inversion)

2Reliability

If scaffolding boards are clamped strongly during transport to prevent displacement, then security is improved, but handling difficulty increases

Engineering Contradiction:

Improvetransport securityVSAvoidhandling ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The scaffolding board design enables self-service during transport through the interaction of recesses and stop limits, which automatically prevent displacement without requiring external clamping. The boards secure themselves through their own structural features, eliminating the need for strong external clamping and improving handling ease.

Inventive Principle:

Principle #25Self-service

3Strength

If scaffolding boards are made of wood to provide strength, then strength is sufficient, but water absorption causes weight increase

Engineering Contradiction:

Improvestructural strengthVSAvoidboard weight

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The patent specifies that the scaffolding board can be made of aluminum or carbon fiber instead of wood. These materials provide sufficient structural strength while being resistant to water absorption, thereby preventing the weight increase that occurs with wooden boards exposed to weather conditions.

Inventive Principle:

Principle #40Composite materials

AI summary

A scaffolding board (1) with a substantially plane top side (2) with a surface for persons staying on it, and with projecting stop limits (3) at the underside (4) of the scaffolding board (1) limiting displacement of the scaffolding board in its longitudinal direction when the scaffolding board is placed on two transverse beams (5), and with recesses (6) provided at the top side (2) of the scaffolding board (1) for receiving the stop limits (3) when two scaffolding boards (1) are superposed.
