Manually-Moved Scaffolding Height Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scaffolding systems require multiple scaffoldings of different types to reach various heights, leading to longer work schedules, increased costs, and safety risks due to frequent climbing on and off the scaffolding.
Innovation Solution
A manually-moved scaffolding system with a transfer assembly and movement means that allows the supporting surface to adjust to different heights using worm gear drive shafts and threaded wheels, enabling the operator to remain on the scaffolding while changing heights and moving it to a workstation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple scaffoldings of different types are used to reach various heights, then the scaffolding can adapt to different work heights, but the quantity of scaffoldings increases and work schedule duration increases
Solution Approach 1:
The patent implements a height adjustment mechanism that allows the supporting surface to be dynamically repositioned to different heights along the basic frame. This dynamic adjustment capability replaces the need for multiple static scaffoldings of different heights, enabling a single scaffolding unit to adapt to various work levels while reducing the time required to deploy and relocate multiple scaffoldings.
Solution Approach 2:
The scaffolding is designed with universal adaptability through its height adjustment system, allowing one multi-functional scaffolding unit to perform the work of multiple single-height scaffoldings. The supporting surface can be positioned at different heights to accommodate various work requirements, making the scaffolding system universally applicable to different height needs without requiring additional equipment.
2Adaptability or versatility
If multiple scaffoldings are used to reach various heights, then different height requirements are met, but the device complexity increases
Solution Approach 1:
The height adjustment mechanism is segmented into modular components including the basic frame with multiple positioning levels, the supporting surface, and the adjustment mechanism itself. This segmentation allows the single scaffolding unit to provide multiple height configurations through its modular structure, replacing the need for multiple complete scaffolding assemblies and thereby reducing overall system complexity.
Solution Approach 2:
By implementing a dynamic height adjustment mechanism within a single scaffolding unit, the system achieves multiple height configurations without requiring multiple static scaffoldings. This dynamic capability consolidates what would otherwise require multiple separate devices into one unit, reducing device complexity while maintaining adaptability to different work heights.
3Ease of operation
If the operator must get off the scaffolding to push it to the workstation, then the transfer assembly can move the scaffolding, but the operator safety risk increases
Solution Approach 1:
The scaffolding incorporates a self-propulsion mechanism that enables the supporting surface to move forward automatically without requiring the operator to dismount and push it manually. The operator remains on the supporting surface and activates the propulsion system, which moves the entire scaffolding assembly to the desired location. This self-service capability eliminates the safety risks associated with climbing on and off the scaffolding while maintaining ease of mobility.
4Adaptability or versatility
If a height adjustment mechanism is added to allow supporting surface movement, then adaptability to different heights is improved, but the device complexity increases
Solution Approach 1:
The height adjustment mechanism employs a dynamic design where the supporting surface can be repositioned along the basic frame through a mechanism that integrates with the existing scaffolding structure. This dynamic adjustment capability allows the supporting surface to move between different height levels without requiring a completely separate complex system, achieving height adaptability while controlling device complexity through clever mechanical integration.
