Removable Trigger Plate Rodent Trap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Prior rodent traps are costly and inconvenient due to one-time use and high bait removal rates without trap activation, leading to inefficiencies in rodent control, especially in large industrial settings.
Innovation Solution
A rodent trap with a removable trigger plate featuring an adhesive layer that ensures rodent motion activates the trap, allowing for easy removal and replacement of the trigger plate and bait, facilitating trap reuse and reducing bait removal without activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bait is placed on a trigger plate to attract rodents, then rodent attraction is improved, but bait removal without trap activation increases
Solution Approach 1:
The trigger plate is segmented from the trap body, allowing it to be removed and replaced. This segmentation enables the trigger plate to be designed as a separate component with specific adhesive properties, while the main trap body retains the activation mechanism. The separable design allows for optimized bait placement on the trigger plate without compromising trap reliability.
Solution Approach 2:
The trigger plate incorporates adhesive material locally at the bait placement area, creating a zone of high friction that prevents bait removal without activation. This localized adhesive property ensures that when a rodent attempts to remove bait, the adhesive engages and triggers the trap mechanism, converting the harmful bait removal action into a useful activation event.
2Reliability
If the entire trap is disposed of after use, then rodent removal is achieved, but cost and inconvenience increase
Solution Approach 1:
The trap is divided into reusable and disposable components. The main trap body including the jaw mechanism and spring are designed to be reusable, while the trigger plate with adhesive is designed to be replaced. This segmentation allows the expensive mechanical components to be retained and reused, while only the consumable trigger plate needs replacement after each use.
Solution Approach 2:
The trigger plate is designed as a disposable component that is discarded after use, while the main trap body is recovered and reused. This approach eliminates the need to dispose of the entire trap assembly, significantly reducing costs and improving productivity for professional sanitarians who use large numbers of traps.
3Reliability
If adhesive is applied to the trigger plate, then rodent motion transfer is improved, but trap complexity increases
Solution Approach 1:
Adhesive material is applied locally to specific areas of the trigger plate where rodent contact is most likely to occur, rather than coating the entire plate. This localized application ensures effective motion transfer while minimizing the complexity of the adhesive application process and maintaining simplicity in the overall trigger plate structure.
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 significantly reduces bait removal without trap activation and enables cost-effective, repeated use of the trap, enhancing efficiency and convenience in rodent control.
Implementation Method 1
an adhesive layer which ensures that motion of the rodent attempting to escape from the trap is transferred to the trap and ensures activation of the trap

AI summary
A rodent trap includes a pivotally mounted jaw which snaps to a closed position to enclose a rodent when activated by a rodent attempting to free itself from an adhesive coated removable trigger member. The trigger member and the rodent can be easily removed from the trap. The trigger member can be replaced with a new trigger member and the trap can be reset and reused.
