Bait Box Locking Mechanism for Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pest control devices fail to securely retain bait within the bait bar, leading to unintended separation when the device's lid is open, allowing animals to access and potentially carry away the bait.
Innovation Solution
A bait support system with a locking mechanism that secures the bait bar to the device's chassis, even when the lid is open, using a post and receptacle configuration that requires disengagement to remove the bait bar, ensuring the bait remains in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a lid is used to lock the bait bar in place, then the bait can be secured when the lid is closed, but the bait bar may not be securely retained when the lid is open, allowing animals to access and carry away the bait
Solution Approach 1:
The locking function is segmented into two independent parts: (1) a receptacle at the first end of the bait bar that receives and retains the bait bar in the enclosure, and (2) a separate locking mechanism at the second end of the bait bar. This segmentation allows each component to perform its specific locking function independently, ensuring reliable bait retention without requiring a complex integrated lid-based locking system.
Solution Approach 2:
The receptacle is pre-positioned in the enclosure to receive the first end of the bait bar before the bait is even placed on the bar. This preliminary positioning ensures that the bait bar is already partially secured when inserted, and the locking mechanism can then complete the securing action. The receptacle and locking mechanism are prepared in advance to work together as a coordinated locking system.
2Ease of operation
If the lid is opened to replace bait, then access is provided for bait replacement, but the bait bar may be freed from the bar holding it, allowing unintended separation
Solution Approach 1:
The locking system is divided into a fixed receptacle portion in the enclosure and a movable locking mechanism portion on the bait bar. This segmentation allows the locking mechanism to be independently actuated to release the bait bar for bait replacement, while the receptacle remains stationary to maintain overall retention. The split design enables controlled access without compromising security.
Solution Approach 2:
The locking mechanism is designed to be dynamically controllable, transitioning between locked and unlocked states. When the lid is opened for bait replacement, the locking mechanism can be actuated to release the bait bar, allowing easy removal and replacement. After replacement, the locking mechanism returns to its locked state, automatically restoring secure retention without requiring manual intervention.
3Adaptability or versatility
If animals can open the pest control device, then access is gained for feeding, but the bait bar and bait can be freed and stripped from the device
Solution Approach 1:
The bait bar is segmented into a first end received by the receptacle and a second end controlled by the locking mechanism. This segmentation allows animals to access the bait feeding area through the enclosure opening while the receptacle and locking mechanism maintain separate, independent control over bait bar retention. The divided locking system prevents animals from simultaneously disengaging both retention points.
Solution Approach 2:
The receptacle is designed to receive and retain the first end of the bait bar in a predetermined position before any animal interaction occurs. This preliminary securing action establishes a baseline retention state that is independent of the locking mechanism. Even if animals manage to manipulate the locking mechanism, the receptacle maintains preliminary retention, preventing complete bait bar removal.

AI summary
A pest control device may include a bait support system. The bait support system may include a bait bar having a first end and a second end. An aperture in the pest control device may receive at least a portion of the first end of the bait bar. A locking mechanism may secure the second end so as to lock the bait bar to the pest control device. The bait bar may be locked to the pest control device when a lid of the pest control device is in an open configuration.
