Pivoting Digging Blades for Efficient Soil Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digging holes in soil or other materials is strenuous and time-consuming due to the inefficiency of existing methods.
Innovation Solution
A hole digging device with pivoted digging blades that can be easily maneuvered to collect and remove soil, featuring a central shaft, crossbar, push rod, and grasping loops that allow the blades to pivot inwardly for efficient soil collection and removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional digging methods are used, then the structure is simple, but the digging process is strenuous and time-consuming
Solution Approach 1:
The digging blades are designed to pivot from an extended position to an inwardly engaged position during the digging cycle. This dynamic movement allows the blades to collect soil efficiently between them while maintaining a relatively simple overall device structure. The pivoting action transforms the blades from a static configuration to an active soil-collecting mechanism.
2Ease of operation
If digging blades pivot inwardly to collect soil, then soil removal efficiency improves, but the device operation becomes more complex
Solution Approach 1:
The digging device is divided into separate functional components: the central shaft, the crossbar, the push rod, and the individually pivoting digging blades. Each blade can pivot independently inward to collect soil, and the segmentation allows for easier operation while managing the complexity through modular design.
Solution Approach 2:
The digging blades utilize the digging force itself to pivot inward. As the user pushes the device into the ground, the resistance from the soil automatically causes the blades to pivot toward each other, collecting soil without requiring additional complex actuation mechanisms. The system serves itself by converting the digging resistance into the blade-pivoting action.
3Loss of time
If manual digging is used, then the device is simple, but the time required to dig holes increases
Solution Approach 1:
The digging blades and soil-collection function are merged into a single integrated device. The blades pivot inward to simultaneously dig and collect soil in one motion, eliminating the need for separate digging and scooping actions. This merging of functions reduces the time required to dig holes while maintaining a relatively simple device structure.

AI summary
A hole digging device comprising a shaft having a crossbar perpendicularly attached; a push rod parallel to the shaft; a circular base on the second end of the push rod and a handle on the first end of the push rod, wherein the handle, push rod, and base can altogether move between an up position and a down position; two braces attached to the shaft on opposing sides; two digging blades pivotally attached to the braces, wherein the digging blades can pivot between an engaged position or a disengaged position; two blade shafts parallel to the central shaft, wherein the digging blades are pivotally attached to the blade shafts; two grasping loops pivotally attached to the crossbar opposite each other and moveable between an up position and a down position; wherein the grasping loops are biased in the down position caused by springs.
