Scaffolding Connection Head With Stepped Receiving Slot
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding component connections experience significant play and uneven force transmission, leading to stress on the edge areas and potential jamming from foreign bodies, which complicates assembly and disassembly.
Innovation Solution
A first scaffolding component with a connection head featuring an upper and lower head part forming a receiving slot, combined with a second component having a perforated disk projection, ensures minimal play and optimized force transmission by centering the components and distributing the load across an extended surface, reducing the risk of jamming from foreign bodies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the connection head and projection are designed with traditional geometry, then assembly is simple, but significant play occurs between components and force transmission is uneven
Solution Approach 1:
The receiving slot is designed with a floor that rises toward the wall, creating a stepped configuration with an inclined end face. This local geometric variation provides a centering effect that guides the projection into proper alignment during assembly, minimizing play while maintaining assembly smoothness through the inclined guide surface.
Solution Approach 2:
The floor of the receiving slot is designed with a stepped profile featuring an inclined end face, adding a dimensional guide feature that actively centers the projection during insertion. This dimensional enhancement ensures minimal play and large-area force transmission without compromising assembly ease.
2Strength
If force is transmitted through a small contact area, then assembly is simple, but stress concentrates on edge areas causing potential failure
Solution Approach 1:
The ceiling and floor of the receiving slot are designed as extended surfaces rather than simple flat planes. This local quality enhancement increases the contact area between the connection head and projection, distributing stress across a larger area to improve load bearing capacity while maintaining structural simplicity.
Solution Approach 2:
The ceiling and floor are designed as extended surfaces in the longitudinal direction, increasing the contact area for force transmission. This dimensional extension enhances strength and load distribution without significantly increasing device complexity.
3Ease of manufacture
If the receiving slot is designed as a simple through-slot, then manufacturing is easy, but foreign objects can become trapped causing jamming
Solution Approach 1:
The floor of the receiving slot features a stepped profile with an inclined end face that slopes toward the opening. This local geometric feature prevents foreign objects from becoming trapped by providing a smooth transition that guides debris out of the slot, eliminating jamming while maintaining ease of manufacture.
4Ease of operation
If the floor of the receiving slot is flat, then manufacturing is simple, but abrupt stops occur during assembly requiring excessive pushing force
Solution Approach 1:
The floor includes a stepped configuration with an inclined end face that provides a gradual transition during assembly. This local geometric feature reduces the pushing force required by eliminating abrupt stops, while the stepped design remains simple to manufacture.
Solution Approach 2:
The floor is designed with a stepped profile in the longitudinal direction, creating an inclined end face that gradually guides the projection into place. This dimensional variation reduces assembly force requirements while maintaining manufacturing simplicity.
