Sand Anchor Using Compressed Gas Suction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing fishing rods in sand, such as burying them, face challenges in balancing the rod's stability against being pulled out by a hooked fish while resisting removal by the fish, leading to potential loss of the rod.
Innovation Solution
A sand anchor utilizing compressed gas, which includes a shank and a plunger with an annular fitting and interior seal, creates a one-way seal to draw sand into the anchor, providing stability for rods by suctioning sand and allowing for easy insertion and removal of the rod.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fishing rod is buried in the sand by digging a hole, then the rod can be secured in the sand, but the rod is difficult to remove when a fish is hooked and there is risk of losing the rod
Solution Approach 1:
The sand anchor is divided into separate components: a shank that is inserted into the sand, a plunger that creates the seal, and a rod holder section. This segmentation allows the rod to be easily attached and detached from the anchor while maintaining secure anchoring in the sand.
Solution Approach 2:
The sand anchor acts as an intermediary device between the fishing rod and the sand. Instead of directly burying the rod, the anchor provides a mechanical interface that secures the rod through compressed air suction while allowing easy removal by releasing the air pressure.
2Stability of the object's composition
If the rod is securely embedded in sand, then stability is improved, but the complexity of insertion and removal procedures increases
Solution Approach 1:
The sand anchor uses compressed air stored in a reservoir to create suction that draws sand into the anchor body, securing it firmly in the ground. The plunger mechanism controls the release of compressed air, simplifying the insertion and removal process while maintaining high stability during fishing.
Solution Approach 2:
The anchor changes its physical parameters by using compressed air to alter the sand density and suction force. When air is released, the suction decreases allowing easy removal; when air is pressurized, suction increases providing firm anchoring, thus dynamically adjusting the anchoring strength without mechanical complexity.
