Self-Tapping Termite Bait Station for Safe Ground Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing termite bait stations are difficult to adjust to changing ground levels, prone to component breakage, require complex extraction and rebaiting processes, and can damage underground infrastructure, with no easy way to monitor bait condition or prevent soil coverage.
Innovation Solution
A self-tapping termite bait station with an elongated cylinder and external screw thread, equipped with a detachable handle and interlocking mechanism, allowing easy implantation and extraction by rotating the cylinder, and featuring slots for bait access and tactile feedback, enabling easy rebaiting and monitoring without damaging underground structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If prior art bait stations are drilled or dug into the ground, then they can be implanted in the earth, but they may puncture water lines, buried telephone lines, internet cables, and electrical lines
Solution Approach 1:
The patent replaces the drilling or digging mechanical system with a screw-threaded insertion system. The external screw threads on the cylinder engage with the soil in a controlled manner, allowing the bait station to be screwed into the ground without the need for drilling or digging, thereby eliminating the risk of puncturing underground utilities.
Solution Approach 2:
The external screw threads on the cylinder enable the bait station to create its own insertion path through the soil without requiring external drilling equipment. The threads self-cut into the ground as the station is rotated and screwed in, providing a self-service implantation mechanism that avoids damage to underground infrastructure.
2Ease of operation
If prior art bait stations are extracted from the ground to check or rebait, then the bait condition can be monitored, but the extraction process structurally breaks and deteriorates components of the device
Solution Approach 1:
The patent divides the bait station into separable components: the handle can be detached from the cylinder, and the cap can be removed. This segmentation allows the user to access and replace bait without extracting the entire station from the ground, preserving component integrity while enabling bait monitoring and replacement.
Solution Approach 2:
The patent extracts only the necessary components (handle and cap) from the overall system, allowing bait access without removing the cylinder from the ground. The handle can be detached to provide access to the bait chamber, and the cap can be removed to replace bait, eliminating the need to extract the entire station and preventing structural damage.
3Ease of manufacture
If prior art bait stations are made with plastic components, then they can be manufactured easily, but the components snap and break off easily during extraction
Solution Approach 1:
The patent introduces dynamic elements to the plastic components, specifically resilient lips that can flex and return to their original position. These resilient features allow the plastic components to withstand the stresses of extraction and reinstallation without breaking, while maintaining ease of manufacture through standard plastic molding techniques.
4Ease of manufacture
If prior art bait stations are placed at a fixed depth, then they can be implanted, but they cannot be height adjusted to accommodate changing ground level conditions
Solution Approach 1:
The patent makes the implantation depth dynamic by allowing the user to control how deep the cylinder is screwed into the ground. The external screw threads enable incremental adjustment of depth, and the station can be extracted and re-implanted at different depths to accommodate changing ground levels, providing adaptability while maintaining a simple implantation process.
5Reliability
If prior art bait stations are implanted in the ground, then they can function as termite bait traps, but the top gets covered by ground soil and gets lost in the dirt and grass overtime
Solution Approach 1:
The patent extends the bait station vertically above ground level, creating a visible portion that serves as a marker for locatability. The cylinder protrudes from the ground surface, allowing users to easily find and access the station for maintenance while the lower portion remains embedded to perform the baiting function.
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
Facilitates easy adjustment to ground levels, reduces component breakage, simplifies rebaiting and monitoring, and prevents damage to underground infrastructure while ensuring effective termite baiting.
Implementation Method 1
An external screw thread is formed on a portion of an outer surface of the cylinder. In a specific embodiment, the screw thread extends from the bottom portions of the ring to the pointed conical end of the cylinder.
Implementation Method 2
external screw thread which, in one embodiment, extends the longitudinal length of the slotted cylinder. The user screws the cylinder into the earth by rotating the cylinder in one direction and causing earth to pass along the external screw threads.
Data Source
AI summary
The termite bait station is screwed into earth via external screw threads. A cylinder chamber holds a bait stick and slots expose the bait to the earth. The cylinder has external outboard threads. The cylinder's top has a ring with an interlock system which is complementary to an interlock system on a collar region of a detachable handle. The detachable handle and lateral handle hold permits the user, upon handle rotation in one direction to be implanted in the earth and upon handle rotation in another direction to be extracted from the earth. Interlocking systems include keys interlockable with keyways; outboard configured depending legs coacting with respective detents; and inboard configured depending legs coacting with respective detents.
