Bait Station With Segmented Housing And Extractable Drawer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vermin baits are unsafe as they can be consumed by non-target animals and humans due to lack of containment, necessitating a solution that ensures selective access and easy replenishment of poisonous bait.
Innovation Solution
A bait station with a housing featuring two opposing doors and a drawer system, where the bait is secured by a bait holding rod and lock mechanism, preventing access to larger animals and humans while allowing vermin entry and exit, and facilitating easy replacement of bait products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an essentially closed housing with doors is provided to prevent non-target animals and humans from accessing the bait, then safety is improved, but device complexity increases
Solution Approach 1:
The housing is divided into two main parts: a base and a lid that can be separated. The lid can be removed or opened to access the interior chamber where bait is placed, while the base remains as a stable foundation with doors for vermin access. This segmentation allows easy servicing and bait replacement without disassembling the entire structure, maintaining safety while reducing complexity.
2Reliability
If the housing is made essentially closed with doors for vermin access, then safety is improved, but ease of operation for bait replacement deteriorates
Solution Approach 1:
The housing is divided into a base and a removable lid. The lid can be easily removed or opened to access the interior chamber for bait replacement, while maintaining the closed structure with doors during normal operation. This allows quick servicing without complex disassembly.
Solution Approach 2:
The bait container or bait tray is designed to be extractable from the housing. A drawer or removable container holds the bait and can be pulled out for refilling or replacement, then easily reinserted. This extraction mechanism simplifies the bait replacement process while maintaining the safety of the closed housing structure.
3Reliability
If a drawer system with holding rod and lock mechanism is used to secure bait, then safety is improved, but device complexity increases
Solution Approach 1:
The bait is stored in a drawer or removable container that can be easily extracted from the housing for refilling and reinserted. This simple extraction mechanism provides sufficient security while allowing easy access for bait replacement, avoiding the need for complex locking systems.
Solution Approach 2:
The drawer or bait container is designed to be self-contained and self-locking through simple mechanical means such as friction fits or simple clips that engage with the housing. This self-service mechanism provides adequate security without requiring complex external locking systems, maintaining ease of operation.
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
The solution provides a safe and efficient means to control vermin by ensuring only target species can access the bait, while allowing for easy maintenance and operation, ensuring the bait is not accessible to non-target animals or humans.
Implementation Method 1
A leaf spring member 50 has a semicircular cutout 52 cooperating with the upper circumferential surface of the holding rod 46 and an inclined ramp portion 54 facilitating inserting of the holding rod 46 into the journal formed by the cutouts 48 and 52 as well as the leaf spring member 50
Implementation Method 2
Now remnants of the bait product 56 can be removed from the holding rod 46 by just letting it drop down under gravity

AI summary
A bait station has a housing (10, 12), slidably receiving a drawer (30) adapted to hold bait product 56. The housing (10, 12) is divided into animal receiving chamber (24) and a bait receiving chamber (26) by means of an intermediate wall (20). The intermediate wall (20) has an opening (46) allowing animals present in the animal chamber (24) to eat from the bait (56) arranged in the bait receiving chamber (26).
