Innovation Solution
A vertical frame design featuring a permanently connected post and transverse arm, with a U-shaped, H-shaped, or h-shaped configuration, utilizing a continuous weld seam for enhanced connection and incorporating apertured discs and connecting heads for secure attachment of horizontal and diagonal elements, allowing for easy assembly and disassembly, and integration with modular scaffolding systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If vertical frames are constructed with detachable connections to enable easy assembly and disassembly, then ease of operation is improved, but structural strength and torsional stiffness deteriorate
Solution Approach 1:
The patent combines detachable connection functionality with permanent weld seams to create a hybrid connection system. The vertical frames include both detachable connecting elements for easy assembly/disassembly and permanent weld seams that provide continuous structural reinforcement and torsional stiffness, merging the advantages of both connection types.
Solution Approach 2:
The connection system uses composite construction combining different connection methods (detachable mechanical connections and permanent welding) within the same vertical frame structure. This allows the frame to exhibit both ease of assembly characteristics and high structural strength simultaneously.
2Ease of operation
If maximum passage height is achieved by reducing frame components, then ease of operation is improved, but structural stability deteriorates
Solution Approach 1:
The patent merges minimal frame configuration with permanent weld seam reinforcement. The vertical frames have a simplified structure to maximize passage height, but incorporate permanent weld seams at critical locations to maintain structural stability without adding significant height-reducing components.
Solution Approach 2:
Permanent weld seams are applied locally at specific critical positions on the vertical frames rather than throughout the entire structure. This provides targeted structural reinforcement where needed to maintain stability while keeping the overall frame configuration minimal for maximum passage height.
3Strength
If permanent connections are used to enhance structural integrity, then strength is improved, but ease of manufacture deteriorates
Solution Approach 1:
The vertical frames are segmented into modular components that can be manufactured separately and then connected. Permanent weld seams are used to join these pre-manufactured segments, allowing each component to be manufactured using standard processes while achieving permanent, high-strength connections through controlled welding operations.
4Adaptability or versatility
If vertical frames are designed for compatibility with modular scaffolding systems, then adaptability is improved, but device complexity deteriorates
Solution Approach 1:
The vertical frames are designed with universal features including standardized connecting heads, apertured discs, and permanent weld seam configurations that enable compatibility with various modular scaffolding systems. The frames can serve multiple functions: providing structural support, enabling easy assembly, and interfacing with different modular components through standardized connection interfaces.
