Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tent stakes are inefficient in driving into various terrains and weather conditions, requiring manual effort and often degrading over time, especially in windy, sandy, or snowy conditions, and are labor-intensive to install for large structures.
Innovation Solution
A power-driven stake system utilizing a coil-shaped stake and an adaptor that fits into a standard drill chuck, allowing the drill to twist the stake into and out of the ground, ensuring axial locking and efficient penetration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pounding is used to drive stakes into the ground, then installation is simple and direct, but it requires significant manual labor and time
Solution Approach 1:
The patent replaces the manual mechanical pounding system with a power-driven rotational system. The stake features a helical blade that converts rotational motion from a power drill into linear penetration, eliminating the need for manual pounding while dramatically increasing installation speed and reducing labor effort.
Solution Approach 2:
The stake incorporates a helical (curved) blade geometry instead of a straight shaft. This curvature enables the stake to spiral into the ground through rotational motion, allowing power-driven installation at high speed while maintaining ease of operation through a simple drill attachment.
2Ease of manufacture
If traditional straight stakes are used, then manufacturing is simple, but they lack effectiveness in hard dirt and sandy conditions
Solution Approach 1:
The stake transitions from a straight geometry to a helical curved geometry. This curvature provides superior engagement with soil particles in hard dirt and sand, significantly improving holding power and reliability across diverse terrains while remaining manufacturable through standard wire forming processes.
Solution Approach 2:
The stake is divided into distinct functional segments: a helical cutting blade for penetration, a shaft for structural support, and a anchoring end for securing. This segmentation allows each part to be optimized for its specific function while maintaining overall manufacturing simplicity.
3Ease of operation
If plastic stakes with large heads are used for easier pounding, then ease of operation improves, but ultraviolet exposure degrades the material over time
Solution Approach 1:
The stake is constructed from metal materials (such as stainless steel or aluminum alloy) that provide both the necessary mechanical properties for easy power-driven installation and superior resistance to UV degradation, eliminating the lifespan problem associated with plastic materials while maintaining operational ease.
4Productivity
If power-driven installation is implemented, then installation speed increases, but device complexity increases due to adaptor requirements
Solution Approach 1:
The stake is designed with a universal attachment mechanism that fits standard power drill chucks, making the system compatible with commonly available tools. This universality allows power-driven installation at high speed without requiring specialized or complex equipment, maintaining simplicity while achieving high productivity.

Data Source
AI summary
Devices, systems, and methods are disclosed which relate to a stake that is twisted into and out of the ground via an adaptor. The adaptor adapts the stake to a power drill, allowing the power drill to twist the stake into and out of the ground by activating the drill. The adaptor is designed to fit a standard drill chuck at one end. At the other end, the adaptor has a fitting to receive the stake. The fitting is such that the stake and adaptor are axially locked so that the stake and adaptor rotate in unison when the drill is activated. The stake is a wire designed in a coil shape with a pilot. The pilot is fit into the adaptor which axially locks the stake with the adaptor.
