Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems face challenges in safe transport and reliable storage of scaffolding decks, as they often result in unstable stacks that can collapse during prolonged storage or transport.
Innovation Solution
A support frame with a form-fitting holding device that secures scaffolding decks vertically, allowing for synchronized lifting and movement with a forklift, and includes longitudinal support devices for even weight distribution and lateral guidance to prevent slipping, enabling safe stacking and handling of multiple decks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If scaffold decks are stacked for storage and transport, then storage efficiency and transport capability are improved, but the stack stability deteriorates and the stacks can collapse during prolonged storage or transport
Solution Approach 1:
The support frame provides a nested structure where multiple scaffold decks are stacked vertically within a single support frame. The uprights form an outer framework that contains and stabilizes the nested scaffold decks, preventing collapse during storage and transport while maximizing space utilization.
Solution Approach 2:
The support frame is prepared in advance with uprights positioned at correct spacing and height. The scaffold decks are pre-positioned within the support frame structure before transport or storage, ensuring proper alignment and stability is established beforehand rather than relying on temporary stacking during handling.
2Stability of the object's composition
If scaffold decks are secured with holding devices, then vertical stability is improved, but the complexity of the support frame increases
Solution Approach 1:
The support frame is divided into modular components: uprights, cross members, and holding devices are separate elements that can be independently manufactured and assembled. This segmentation allows each component to be optimized for its specific function while maintaining overall simplicity through standardized connections.
Solution Approach 2:
The holding devices serve multiple functions: they provide vertical stabilization of scaffold decks, enable positive locking engagement, and facilitate uniform weight distribution. This multi-functionality reduces the need for additional separate components, thereby limiting the increase in overall device complexity.
3Quantity of substance
If multiple scaffold decks are stacked high, then storage efficiency is improved, but the risk of toppling over increases
Solution Approach 1:
Multiple scaffold decks are nested vertically within the confines of the support frame uprights. The uprights act as containing walls that prevent lateral displacement and toppling, allowing high stacking numbers to be achieved safely by providing continuous lateral support throughout the stack height.
Solution Approach 2:
The support frame structure is prepared in advance with uprights positioned to provide lateral containment. This preliminary structural framework ensures that when scaffold decks are stacked to high numbers, the lateral support is already in place to prevent toppling, rather than relying on the decks themselves to provide stability.
4Reliability
If a positive-locking retaining device is added for synchronized lifting, then transport safety is improved, but the device complexity increases
Solution Approach 1:
The positive-locking retaining device is merged with the existing holding device structure. The same mechanical components that provide vertical stabilization also serve as the positive-locking mechanism for synchronized lifting, eliminating the need for a completely separate lifting device and thereby limiting the increase in overall complexity.
Solution Approach 2:
The holding devices are designed to perform multiple functions: vertical stabilization of scaffold decks, positive locking engagement to prevent slippage, and providing attachment points for synchronized lifting operations. This multi-functionality allows transport safety features to be integrated into existing structural elements rather than adding separate dedicated components.
