Multifunction Scaffold Side Rail with Locking Pin
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional scaffolds have limited elevation adjustment capabilities due to their supporting structures, preventing the deck from being mounted close to the ground or as high as desired, as they often inhibit stable mounting at various elevations.
Innovation Solution
A side rail assembly with adjustable height and a locking pin system that allows the deck to be securely mounted at multiple orientations, utilizing vertically aligned slots and a biasing mechanism to engage the locking pin, enabling a wide range of elevation and mounting options without requiring separate latch mechanisms for each orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional supporting structures are used, then the scaffold structure is simple, but the range of elevations that can be safely supported is limited
Solution Approach 1:
The side rail assembly is designed to function in multiple orientations (first and second orientations) to support the deck at different elevations. The same assembly with vertically aligned slots and locking pin mechanism serves both orientations, eliminating the need for separate structures for each elevation range.
Solution Approach 2:
The side rail assembly can be reconfigured between different orientations by removing and repositioning the locking pin in vertically aligned slots. This dynamic reconfigurability allows the scaffold to adapt to different elevation requirements without changing the fundamental structure.
2Adaptability or versatility
If the supporting structures jut significantly downward, then the structure is stable, but the deck cannot be mounted close to the ground
Solution Approach 1:
The side rail assembly can be reconfigured between different orientations by removing and repositioning the locking pin in vertically aligned slots. This dynamic reconfigurability allows the scaffold to adapt to different elevation requirements without changing the fundamental structure.
Solution Approach 2:
The side rail assembly can be inverted to a second orientation where the support surfaces face upward, allowing the deck to be mounted close to the ground. The vertically aligned slots ensure the locking mechanism works equally well in both upright and inverted configurations.
3Adaptability or versatility
If the supporting structures jut significantly upward, then the deck can be mounted high, but stable mounting points are not available at lower elevations
Solution Approach 1:
The side rail assembly is designed to function in multiple orientations (first and second orientations) to support the deck at different elevations. The same assembly with vertically aligned slots and locking pin mechanism serves both orientations, eliminating the need for separate structures for each elevation range.
Solution Approach 2:
The side rail assembly is divided into segments with vertically aligned slots that allow the locking pin to be positioned at different heights. This segmentation enables flexible mounting at various elevations while maintaining structural integrity.
4Reliability
If separate latch mechanisms are used for each orientation, then each orientation is securely locked, but the device complexity increases
Solution Approach 1:
A single locking pin mechanism with vertically aligned slots serves both orientations. The locking pin can be inserted through aligned slots in either the first or second orientation to secure the deck, eliminating the need for separate latch mechanisms while maintaining reliable locking in both configurations.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides enhanced stability and safety by allowing the deck to be securely mounted at various elevations, increasing the maximum height and decreasing the minimum height, while eliminating the need for additional tools or mechanisms, thus expanding the scaffold's adjustment range.
Implementation Method 1
The locking pin assembly may comprise a shaft, a locking tab, and a biasing member to bias the locking tab into engagement with the deck

AI summary
A side rail assembly useful for securing a deck of a scaffold comprises a side rail configured to be supported between two ladder frames in first and second orientations. The side rail includes first and second support surfaces for supporting the deck in the first and second orientations, respectively. First and second vertically aligned and closed slots are formed in respective opposing surfaces of the side rail. The side rail assembly further comprises a locking pin assembly to secure the deck against one of the support surfaces of the side rail depending on the orientation. The locking pin assembly is configured to be removably engaged with the first and second slots of the side rail in both the first and second orientations.
