Hydraulic Stake Puller Layout for Fast Extraction at Any Angle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for removing tent stakes from the ground are inefficient, particularly for larger stakes, as they are either labor-intensive, difficult to maneuver, or too large and expensive for smaller jobs, and most are designed to work optimally with stakes perpendicular to the ground.
Innovation Solution
A hydraulic device with a motor-connected piston system that allows for two-stroke extraction of tent stakes, featuring adjustable angle capability, a safety shield, and a rotational handle system to reduce user strain, designed to accommodate common tent stake sizes and types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If hydraulic pullers are used to extract stakes, then extraction speed and efficiency are improved, but the device becomes heavier and more difficult to maneuver
Solution Approach 1:
The hydraulic stake puller is divided into separate functional modules: a hydraulic power unit, a piston assembly with claws, and a handle control system. This segmentation allows the main hydraulic mechanism to remain stationary while only the lightweight piston and claw assembly needs to be maneuvered to each stake location, improving ease of operation while maintaining high extraction speed through the hydraulic system.
2Ease of operation
If traditional car jack type pullers are used, then ease of operation at angles is improved, but extraction speed and labor intensity worsen
Solution Approach 1:
The piston assembly is designed to be dynamically positionable at various angles relative to the stake, unlike fixed-axis hydraulic systems. The lightweight piston with attached claws can be oriented at different angles to match stake orientations, providing angular flexibility similar to car jacks while achieving rapid extraction through hydraulic power instead of manual cranking.
3Force
If heavier equipment such as excavators are used, then extraction power is improved, but device size and cost increase
Solution Approach 1:
The invention extracts only the essential stake-extraction function from large heavy equipment like excavators. By using a focused hydraulic piston system dedicated solely to pulling stakes, the design achieves sufficient extraction power for tent stakes without the unnecessary bulk, complexity, and cost of full excavator equipment, thereby reducing device size while maintaining adequate force.
4Productivity
If single-stroke extraction devices are used, then extraction speed is improved, but adaptability to different stake sizes and angles deteriorates
Solution Approach 1:
The piston assembly with its two claws is designed to accommodate various stake sizes and orientations through universal positioning capability. The claws can engage different stake types (e.g., 6-12 inch stakes or meter-long stakes) and the piston can be positioned at various angles, making the same device adaptable to multiple stake configurations while maintaining rapid two-stroke extraction performance.

Data Source
AI summary
A method for using a tool to extract tent stakes from the ground is disclosed. The tool has a portion that houses the motor and hydraulic fluid tank, and a hydraulic cylinder portion the user holds against a tent stake and operates to pull the tent stake. Hydraulic hoses connect the two portions. Separating the motor from the hydraulic cylinder allows the user to manipulate just the portion performing work on the tent stake without having to also lift or stabilize the larger and heavier motor portion. Rotating a handle causes the hydraulic cylinder to extend or retract. A hand guard may be present to prevent accidental crush injuries. The tool is designed to fully extract a stake in two strokes of the hydraulic cylinder.
