Solution Overview

Problem

Existing scaffold covers are cumbersome to attach, remove, and store, and are often fragile, leading to inefficiencies and increased costs in construction and maintenance operations.

Innovation Solution

A scaffold cover assembly featuring a roller and connectors that allow the cover to be easily rolled up and down, and reversibly fixed to a fixing member, which disconnects at a predetermined tension to prevent damage from strong winds or precipitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a cover is attached to protect the workspace, then protection against environmental factors is improved, but ease of operation deteriorates due to cumbersome attachment and removal

Engineering Contradiction:
Improveprotection against wind and precipitationVSAvoidattachment and removal operations
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The cover is designed to be dynamically attachable and detachable through a roller mechanism with connectors that can be easily engaged and disengaged from fixing members, transforming the static attachment process into a dynamic, easily reversible operation

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The cover system is divided into separate components (cover, roller, connectors, fixing members) that can be independently handled and assembled, making the attachment and removal processes simpler and more manageable

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a cover is permanently fixed to the scaffold, then stability is improved, but adaptability deteriorates when wind or precipitation requires temporary removal

Engineering Contradiction:
Improvecover fixation stabilityVSAvoidtemporary removal capability
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The connection system uses reversible connectors that provide stable fixation during normal conditions but can be quickly released when environmental conditions change, allowing the system to transition between stable and adaptable states as needed

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The connectors are designed to automatically engage with the fixing members and can be easily disengaged by workers without requiring complex tools or procedures, making the system self-sufficient for both attachment and removal operations

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If strong winds act on the cover, then protection function is maintained, but damage risk increases due to excessive tension on the cover material

Engineering Contradiction:
Improvewind resistanceVSAvoidcover material integrity
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The connector design incorporates a predetermined tension threshold that allows the cover to disconnect from the fixing member before the material reaches its breaking point, cushioning against damage by releasing excess tension caused by strong winds or accumulated precipitation

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The predetermined tension mechanism converts the harmful effect of strong winds and precipitation accumulation into a beneficial automatic disconnection feature, where the force that could damage the cover instead triggers a protective release mechanism

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

AI summary

An assembly (100) comprises a scaffold (103) for operable positioning at and/or against a portion of a construction and providing a work space (W) for a worker, and a cover (119) for protecting at least part of the work space (W), extending from a proximal end to a distal end (D), a roller (117) in use mounted on the scaffold (103) on a first position, and a fixing member (121) in use mounted on another position, the roller (117) supporting the proximal end of the cover (119) and configured to reversibly roll a portion of the cover (119) to/from a rolled-up configuration from/to an unrolled configuration to (un-)cover at least part of the work space (W), and one or more connectors (123) configured to reversibly fix the distal end (D) of the cover (119) to the fixing member (121) and reversibly disconnect the distal end (D) from the fixing member (121) at at least a predetermined tension on the distal end pulling the distal end from the fixing member.
