Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If welding limit plates on the support frame and manual pushing/pulling/twisting are used for positioning, then the steel structure can be installed from lifting state to assembly state, but it is difficult to achieve accurate positioning and requires significant manual labor with safety risks
Solution Approach 1:
The spherical sliding device automatically positions the steel structure by sliding along the arc-shaped groove under gravity, eliminating the need for manual pushing, pulling, and twisting operations. The system serves itself by using the gravitational force and the geometric constraint of the arc-shaped groove to achieve precise positioning automatically.
Solution Approach 2:
The invention uses a spherical sliding device that moves along an arc-shaped groove, utilizing curved geometric paths to control the positioning trajectory. The spherical shape combined with the arc-shaped groove creates a natural sliding path that guides the steel structure to its precise installation position without manual intervention.
2Productivity
If the cutting plate method is used for uninstallation, then steel structures can be removed from the support frame, but construction efficiency is reduced due to time-consuming cutting operations
Solution Approach 1:
The uninstallation process is segmented into discrete steps using the jacking mechanism to incrementally lift the steel structure in stages. By dividing the removal process into multiple controlled lifting operations with gasket adjustments, the system avoids time-consuming cutting operations while maintaining safety and precision throughout the uninstallation sequence.
Solution Approach 2:
The invention replaces the traditional mechanical cutting method with a jacking mechanism that uses controlled mechanical lifting and separation. Instead of cutting the support steel plate, the jacking mechanism gradually elevates the steel structure to separate it from the support frame, significantly reducing uninstallation time and eliminating the need for cutting operations.
3Ease of manufacture
If manual operations are performed on high-altitude support frames with confined operating space, then installation can be completed, but significant safety risks are posed during construction
Solution Approach 1:
The spherical sliding device performs the positioning function automatically through gravity-driven sliding along the arc-shaped groove, eliminating the need for workers to manually push, pull, or twist heavy steel structures in confined high-altitude spaces. This automated self-positioning mechanism significantly reduces safety risks while completing the installation.
Solution Approach 2:
The arc-shaped groove acts as an intermediary guide that channels and controls the movement of the spherical sliding device. This intermediate geometric feature provides a predetermined safe path for the steel structure to follow during positioning, eliminating the need for direct manual manipulation in dangerous high-altitude confined spaces.
