Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ground securing rods, designed for soft sand, fail to effectively penetrate compacted earth due to excessive force requirements and material strength limitations, making them unsuitable for hand-driven installation in various ground types.
Innovation Solution
A hollow metal rod with a flat helical section and cone-shaped reinforcement at the drive-in end, combined with a torsion lever system and upper reinforcing piece, allows for increased torque and axial thrust, enabling hand-driven installation in both soft sand and compact dirt.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a helical projection is added to the end of a hollow rod to facilitate ground penetration, then the ease of installation is improved, but the device breaks easily when driven into compacted earth
Solution Approach 1:
The rod is divided into multiple sections with different structural characteristics: a hollow body for lightweight construction, a flattened section for ground engagement, and a conical reinforcement zone for strength. This segmentation allows each part to perform its specific function optimally without compromising the whole.
Solution Approach 2:
The rod features localized structural modifications: a flattened section with helical projection for ground penetration, and a conical reinforcement zone with increased wall thickness at the drive-in end. These local quality changes provide the necessary strength and grounding capability without making the entire rod overly complex or heavy.
2Ease of operation
If the rod design is optimized for soft sand penetration, then the ease of operation in beach conditions is improved, but the device cannot penetrate compacted earth
Solution Approach 1:
The rod's geometry is modified by flattening a section and adding a helical projection, changing the physical parameters of the drive-in end. This allows the same rod to effectively penetrate both soft sand and compacted earth by providing sufficient surface area for sand engagement and sufficient edge sharpness for compacted earth penetration.
Solution Approach 2:
The rod design incorporates a universal drive-in mechanism that can effectively penetrate different ground types. The flattened section with helical projection serves multiple functions: providing grip in soft sand and cutting edge in compacted earth, making the device versatile for various grounding conditions.
3Force
If excessive thrust and torsion are required to drive the rod into the ground, then the penetration capability is improved, but the device cannot be driven in by hand
Solution Approach 1:
The rod features a flattened section rather than a perfectly cylindrical shape, creating curved surfaces that facilitate rotation and penetration. The helical projection adds a spiral curvature that provides mechanical advantage during twisting, reducing the manual force required while maintaining effective penetration capability.
Solution Approach 2:
The rod's flattened section with helical projection creates a dynamic penetration mechanism where the user applies alternating twisting and thrusting motions. This dynamic action reduces the peak force required compared to direct axial pounding, making hand-driven installation feasible while still achieving sufficient penetration into compacted earth.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The novel rod design enhances torsional strength and axial force application, allowing secure penetration of different ground types by hand, improving usability and durability while maintaining cost-effectiveness.
Implementation Method 1
reducing its diameter in combination with stamping it in order to flatten it, whereby it is twisted until the flat helical section is formed
Implementation Method 2
at its base a cone-shaped reinforcement that improves the torsional strength of this area
Implementation Method 3
the lever runs all the way through the rod, forming with said rod a cross that makes it possible, when implanting the rod, to exert a great deal of torque, as well as powerful axial thrust

AI summary
A ground securing rod includes a hollow metal rod (1), whose drive-in end has a flat helical section whose diameter is slightly larger than that of the bar (2), terminating in a tip (3). The section is made with the body of the rod (1) itself by a reduction in its diameter in combination with stamping of the rod in order to flatten it, whereby it is twisted until the helical section is formed, which has a cone-shaped reinforcement at its base (4), while at its upper end the rod (1) has an attached upper reinforcing piece (5), having a seat (6) for a torsion lever (7) that can be inserted into a through opening (8) located at the upper end of the rod and is positioned in the area covered by the upper reinforcing piece (5).
