Scaffold Arrangement With Backup Locking Member
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffold arrangements fail to securely and reliably support scaffold components like climbing scaffold screens on tall scaffolding structures, risking accidental disengagement and uncontrolled downward movement, which is particularly hazardous during high-rise construction.
Innovation Solution
A scaffold arrangement featuring a support unit with a mounting portion, a supporting member, and a releasable locking member that acts as a backup to prevent uncontrolled downward movement, utilizing a slidable locking arm and locking pin mechanism to ensure secure attachment and easy disengagement, with a pivoting supporting member that can stow within the scaffold's footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a releasable locking mechanism is used to support scaffold components, then ease of operation for deliberate disengagement is improved, but reliability against accidental disengagement deteriorates
Solution Approach 1:
The locking member is designed to be moveable between locked and unlocked positions, allowing dynamic control of the scaffold component's attachment state. The supporting member can pivot between supporting and stowed positions, enabling adaptive configuration. This dynamic design facilitates easy deliberate disengagement while maintaining secure locked state during normal operation.
Solution Approach 2:
The locking member is positioned to engage with the scaffold component before any potential accidental disengagement can occur. The supporting member is pre-configured in a supporting position that projects laterally to provide immediate support. This preliminary positioning ensures that the scaffold component is secured before any failure mode can activate, preventing accidental disengagement while allowing controlled release when needed.
2Reliability
If a secure locking mechanism is implemented to prevent accidental disengagement, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking member and supporting member are integrated into a single support unit assembly, combining multiple functions into one compact structure. The locking member serves both as a positional constraint and a safety backup, while the supporting member provides both primary support and a stowed configuration. This merging reduces the number of separate components and simplifies the overall mechanism while maintaining high reliability.
Solution Approach 2:
The locking member performs multiple functions: it locks the scaffold component in position, provides a backup support surface, and engages with the supporting member to prevent unauthorized movement. The supporting member serves as both a primary support structure and a stowable element that can be repositioned. This multi-functionality reduces the need for additional specialized components, simplifying the overall device while enhancing reliability.
3Object-affected harmful factors
If a backup supporting member is added to arrest uncontrolled downward movement, then safety is improved, but device complexity increases
Solution Approach 1:
The locking member is positioned and configured to serve as a backup support surface before any uncontrolled downward movement can occur. If the primary supporting member fails or the scaffold component becomes dislodged, the locking member is already in position to arrest the downward movement and prevent catastrophic failure. This beforehand cushioning approach adds a safety layer without requiring complex active monitoring or control systems.
Solution Approach 2:
The locking member acts as an intermediary element between the scaffold component and the support unit structure. It provides a intermediate level of support and constraint that mediates between the primary supporting member and the scaffold component, preventing direct uncontrolled movement while maintaining a relatively simple overall structure. This intermediary function adds safety without proportionally increasing complexity.
4Ease of operation
If the supporting member projects laterally to support the scaffold component, then ease of operation for attachment is improved, but area occupied by the support unit increases
Solution Approach 1:
The supporting member is designed to pivot between a supporting position where it projects laterally from the scaffold assembly and a stowed position where it is contained within the footprint of the scaffold assembly. This dynamic reconfiguration allows the supporting member to provide easy lateral access for scaffold component attachment when needed, while minimizing the occupied area when not in use, thus resolving the contradiction between operational ease and space occupation.

AI summary
A scaffold arrangement (1) comprising a scaffold component (2) and a support unit (3) for releasably supporting the scaffold component in an operative position on a scaffold assembly or building, the support unit (3) comprising a mounting portion for fixedly mounting the support unit to said scaffold assembly, a supporting member for seating a first part of the scaffold component, and a releasable locking member moveable to a locking position for locking the scaffold component to the support unit, the arrangement being such that when the scaffold component (2) is seated on the supporting member in said operative position, and the locking member is in said locking position, the locking member is spaced immediately below a second part of the scaffold component (2) and acts as a back-up supporting member for arresting uncontrolled downward movement of the scaffold component (2) relative to the support unit (3).
