Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current scaffolding systems are complex, expensive, and pose safety risks due to inadequate connection mechanisms, leading to instability and potential tripping hazards, especially when extending for thermal insulation applications.
Innovation Solution
A hanging hook mechanism with a horizontal slot and support pin, allowing for secure attachment and detachment of scaffolding extensions without additional tools, using a U-shaped component that blocks unwanted movement and provides a stable load-bearing attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If scaffolding floor extensions are made robust and load-bearing with additional triangular supports and connections, then stability and load-bearing capacity are improved, but device complexity and cost increase
Solution Approach 1:
The connection mechanism is divided into separate functional elements: a U-shaped component for attachment, a support pin for positioning, and a triangular support for stabilization. This segmentation allows each element to perform its specific function independently, simplifying the overall design while maintaining robustness.
Solution Approach 2:
The support pin acts as an intermediary element between the U-shaped attachment component and the triangular support structure. It provides a simple mechanical link that transmits loads while enabling easy assembly and disassembly without complex connection mechanisms.
2Area of stationary object
If scaffolding floor extensions are positioned lower to extend further from the wall, then working space for thermal insulation applications is improved, but tripping hazards increase
Solution Approach 1:
The scaffolding floor extension is designed to be dynamically adjustable in position. The telescoping mechanism allows the extension to be extended further when needed for thermal insulation work and retracted when not needed, thereby adapting the working space while minimizing tripping hazards.
Solution Approach 2:
The extension mechanism is pre-configured with the U-shaped components and support pins in a retracted position, ready to be extended only when thermal insulation work is required. This preliminary preparation allows the system to provide maximum working space when needed while maintaining a safe, compact configuration otherwise.
3Ease of operation
If telescoping outriggers are used for easy activation of scaffolding extensions, then ease of operation is improved, but reliability of attachment decreases
Solution Approach 1:
The telescoping outriggers are designed to self-align and self-lock into position through their mechanical geometry. The U-shaped components automatically engage with the support pins when the extension is moved into position, providing reliable attachment without requiring additional fastening operations.
Solution Approach 2:
The U-shaped components feature curved surfaces that guide the support pins into proper alignment during the extension process. This curved geometry ensures that the connection elements engage smoothly and reliably, maintaining both ease of operation and attachment security.
4Reliability
If scaffolding deck parts are made firmly connected to prevent lifting, then safety is improved, but ease of assembly and disassembly decreases
Solution Approach 1:
The connection mechanism transitions from a static, permanent connection to a dynamic, reversible connection. The U-shaped components with support pins provide firm connection during assembly through simple insertion and engagement actions, while enabling equally simple removal when disassembly is required.
Solution Approach 2:
The complex fastening and securing operations are extracted and replaced by a simple insertion mechanism. The support pins are inserted through holes in the scaffolding deck parts and engaged by the U-shaped components, eliminating the need for multiple fastening steps while maintaining safety.

AI summary
The scaffold has vertical arms (1) arranged at a distance to each other and connected to an adjusting frame over a horizontally-aligned latch (2). Horizontal scaffold base parts (4) are arranged on the frame and connected with one another. The base parts lie on a support pin (6) by a rigidly connected hook (5). The support pin is horizontally aligned and fastened to the vertical arms. The hook is perpendicularly aligned with respect to the support pin and penetrated via a horizontal slot. The hook projects from a perpendicular edge, and is moved over the support pin. An independent claim is also included for a method for fastening a scaffold bottom extension to a scaffold.
