Foldable Cantilever Structure Manual Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foldable cantilevered work structures for supporting formwork panels are cumbersome due to heavy assistance systems, requiring tools for adjustment and limiting independent length adjustment of side frames, which increases mass and complexity.
Innovation Solution
A foldable cantilevered work structure with rolling members at the interface between guide members allows for manual, tool-free adjustment of side frames, reducing friction and eliminating the need for gear assistance, resulting in a lighter and more economical design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a gear assistance system is used to move lateral frames, then the force required by the operator is reduced, but the mass and complexity of the structure increase
Solution Approach 1:
The invention extracts and eliminates the gear assistance system from the structure, replacing it with a direct manual sliding mechanism on guide members. This removal of the gear system reduces mass and complexity while maintaining operational feasibility through the guide member design
Solution Approach 2:
The invention substitutes the gear mechanical assistance system with a simplified mechanical sliding system on guide members. The guide members provide a low-friction path for lateral frame movement, replacing the need for gear-based force multiplication
2Ease of operation
If pneumatic or hydraulic assistance systems are used for adjusting lateral frames, then the adjustment effort is reduced, but the device complexity and cost increase
Solution Approach 1:
The invention extracts and removes pneumatic and hydraulic assistance systems from the structure, replacing them with a purely mechanical guide member system that enables tool-free manual adjustment without requiring complex fluid power components
Solution Approach 2:
The guide members enable the lateral frames to be moved and adjusted directly by the operator through simple manual force, making the system self-sufficient without requiring external pneumatic or hydraulic power sources
3Ease of operation
If connecting rods are used to simultaneously separate lateral frames, then the adjustment is assisted, but the mass and footprint of the assistance system increase
Solution Approach 1:
The invention segments the adjustment function, allowing each lateral frame to be adjusted independently through its own guide members rather than using a coupled connecting rod system. This segmentation eliminates the need for heavy connecting rods while maintaining adjustment capability
Solution Approach 2:
The invention extracts and removes the connecting rods system, replacing it with independent guide members for each lateral frame that enable assistance-free adjustment without requiring a coupled mechanical linkage system
