Universal Slab Removal Anchor Assembly Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing slab removal devices require complex anchoring systems and often necessitate jackhammering, which is inefficient and risky, especially when dealing with large slabs of cement or concrete.
Innovation Solution
A universal slab removal device featuring an anchor assembly with an elongated anchor member and self-setting concrete anchors that can be easily fastened to slabs, allowing for lifting and moving using any type of lifting machine without the need for jackhammering, utilizing a combination of fork lift forks and strap connectors for secure lifting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex anchoring systems are used to securely fasten slabs, then the reliability of slab fixation is improved, but the device complexity increases
Solution Approach 1:
The anchoring system is divided into separate functional components: U-shaped clamps for gripping the slab edges, independent anchor bolts for each corner, and separate lifting points. This segmentation allows each component to perform its specific function reliably while keeping the overall system simple and modular.
Solution Approach 2:
Instead of anchoring to the bottom or requiring jackhammering into the slab, the device inverts the approach by using U-shaped clamps that grip the top edges of the slab. This inverted anchoring method eliminates the need for complex penetration anchoring while maintaining secure fixation.
2Reliability
If jackhammering is used to create lifting points, then the anchoring reliability is improved, but the operational safety deteriorates due to risks and inefficiency
Solution Approach 1:
The lifting points are pre-formed as integral parts of the anchor assembly structure, with designated fork lift insertion points built into the design. This preliminary preparation eliminates the need for dangerous jackhammering operations during actual slab removal, as all anchoring and lifting points are ready in advance.
Solution Approach 2:
The anchor assembly acts as an intermediary device that provides safe, pre-prepared lifting points without requiring direct jackhammering operations. The fork lift interacts with the anchor assembly rather than requiring workers to perform dangerous jackhammering, thus eliminating the harmful effects while maintaining anchoring reliability.
3Object-affected harmful factors
If specialized removal equipment is used to safely remove slabs, then the operational safety is improved, but the ease of operation deteriorates due to equipment requirements
Solution Approach 1:
The anchor assembly is designed to be universally compatible with standard fork lift equipment, allowing common material handling machinery to perform the specialized function of safe slab removal. The U-shaped clamps and lifting points work with any fork lift, eliminating the need for specialized custom equipment while maintaining safety.
Solution Approach 2:
The anchor assembly is self-contained with all necessary anchoring components (U-shaped clamps, anchor bolts, nuts, washers) integrated into a single unit that attaches directly to the fork lift. This self-service design simplifies operation by eliminating the need for multiple separate equipment pieces or complex assembly procedures during the removal operation.
