Modular Scaffolding Platform with Interlocking Hooks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional scaffolding systems used by tradespeople, such as plasterers, are not easily movable and often require multiple units to be rearranged, which is inefficient and unsatisfactory due to their fixed dimensions and lack of stability when connected.
Innovation Solution
A modular platform system comprising modules with longitudinal and transverse edges, adjustable supports, and S-shaped connecting hooks with flat central parts and 90° bent wings, allowing for secure and stable connection and easy movement of multiple modules as a single unit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional scaffolding with fixed dimensions is used, then structural stability is maintained, but adaptability to different work places deteriorates
Solution Approach 1:
The scaffolding system is divided into modular units ( Modules A and B) with standardized connection points. Each module can be independently positioned and connected to others, allowing flexible adaptation to different work spaces while maintaining structural integrity through standardized interfaces.
Solution Approach 2:
The connecting hooks are designed with universal S-shaped geometry that can connect any module to any other module regardless of position or orientation. The standardized hook design with central plate and bent wings creates a universal connection interface that works across all module configurations.
2Ease of operation
If multiple scaffoldings are connected together, then coverage area is increased, but ease of movement deteriorates
Solution Approach 1:
The connection system transitions from rigid fixed connections to dynamic adjustable connections. The S-shaped hook with flat central plate allows modules to be connected in various orientations and positions, enabling the entire scaffolding assembly to be moved as a unified structure while maintaining connection stability through the geometric interlocking of hooks and modules.
3Reliability
If S-shaped hooks with round section are used for connection, then manufacturing simplicity is achieved, but connection stability deteriorates
Solution Approach 1:
The connecting hook geometry transitions from symmetric round section to asymmetric S-shape with flat central plate and bent wings. This asymmetric geometry provides stable interlocking when connected, preventing relative translation between modules while maintaining manufacturing feasibility through standard metal forming processes.

AI summary
The platform has a hook (52) having an axis (60) parallel to a flat central part (54), at a level of a wing (56). The axis is oriented toward an end of the central part to cooperate with an orifice at a level of an upper surface of floors of two parallelepiped modules. The hook has a first tube (64) parallel to the central part at a level of another wing (58). The first tube is oriented toward another end of the central part to cooperate with a second hollow tube that is integrated to the floor of each module. The second tube has a section adapted to a section of the first tube.
