Solution Overview

Problem

Current methods for mounting scaffolds on high-rise buildings require extensive setup along the entire facade for roof repairs, which is time-consuming and costly, and do not efficiently utilize the eaves area for scaffold placement.

Innovation Solution

A suspended working scaffold is mounted along the eaves by attaching separate scaffolds with hinge joints and coupling catwalks between them, allowing for rapid and economical setup and disassembly, with adjustable stands and protective rail systems for stability and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a scaffold is constructed along the entire facade from the ground for roof repairs, then safety is ensured, but the setup is time-consuming and costly

Engineering Contradiction:
ImprovesafetyVSAvoidsetup time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The scaffold system is divided into multiple separate suspended scaffold units that can be independently mounted on the roof eaves. Each unit consists of a support unit with stands, catwalk, and protective railing, fastened to the roof structure. These segmented units are then coupled together to form a continuous working platform, enabling rapid deployment without constructing a single large ground-based scaffold.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention transitions from ground-based scaffold construction to roof-mounted suspended scaffolds. By mounting the scaffolds from the roof eaves and swinging them down to the working position, the system eliminates the need for extensive ground-based assembly, significantly reducing setup time while maintaining safety through proper roof anchoring and protective railings.

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

2Area of stationary object

If a scaffold is constructed along the entire facade from the ground, then complete coverage is achieved, but the cost increases

Engineering Contradiction:
Improvescaffold coverage areaVSAvoidcost
Core Design Contradiction:
Area of stationary objectVSEase of manufacture

Solution Approach 1:

The continuous scaffold coverage is achieved by coupling multiple identical, modular suspended scaffold units together. Each unit is a self-contained module with support unit, stands, catwalk, and protective railing that can be independently manufactured and then assembled on-site, reducing overall cost compared to a single custom-built ground scaffold.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The suspended scaffold units are designed as universal, multi-functional modules that can be used for various roof repair tasks. Each unit provides catwalk for worker access, protective railing for safety, and can be positioned at different locations along the eaves, making them adaptable to different building configurations and repair needs.

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

3Productivity

If separate scaffolds are mounted on the roof and swung past the eaves, then rapid deployment is achieved, but the complexity of mounting increases

Engineering Contradiction:
Improvedeployment speedVSAvoidmounting complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The support units are pre-assembled on the roof with hinge joints and fastening mechanisms prepared in advance. The stands are pre-attached to the support units with coupling mechanisms ready, allowing the entire scaffold unit to be quickly swung down to the working position and locked into place without complex on-site assembly procedures.

Inventive Principle:
Principle #10Preliminary action

4Area of stationary object

If catwalks are coupled between separate scaffolds to form a continuous catwalk, then a complete working platform is obtained, but the number of components increases

Engineering Contradiction:
Improvecontinuous catwalk areaVSAvoidnumber of components
Core Design Contradiction:
Area of stationary objectVSQuantity of substance

Solution Approach 1:

The continuous catwalk is formed by coupling multiple identical modular catwalk sections together. Each catwalk section is a standardized component that attaches to the stands of adjacent scaffold units, creating a continuous walking surface. This modular approach allows the catwalk to be assembled from discrete, manageable components rather than requiring a single large custom-built structure.

Inventive Principle:
Principle #1Segmentation

AI summary

A suspended working scaffold is mounted along the eaves (12) of a roof by mounting and fastening a number of separate scaffolds on the roof with hinge joints (21) and swinging them past the eaves. Then, catwalks (37) are coupled between the catwalks (13) of the scaffolds in such a manner that a continuous catwalk is obtained along the eaves.
