Solution Overview

Problem

Current rodent traps are unsightly, unsanitary, and pose safety risks due to their design, and existing enclosure-type traps do not offer a compact footprint for tight spaces or the option of reuse.

Innovation Solution

A compact enclosure-type mouse trap with a guillotine killing mechanism, featuring a pivoting link element that sets the trap and conceals the rodent, allowing for easy disposal and reuse, made of durable plastic with a U-shaped pathway to ensure containment and a smaller footprint.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a snap trap with spring operated mechanism is used, then the rodent is instantly killed, but the trap is unsightly, unsanitary, and dangerous to children and pets

Engineering Contradiction:
Improvekilling effectivenessVSAvoidsafety risks and sanitation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The trap is divided into separate functional modules: a housing enclosure, a guillotine killing mechanism, a trigger mechanism, and a disposal system. This segmentation allows the harmful killing function to be isolated within a safe enclosure while maintaining effectiveness.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The guillotine mechanism serves as an intermediary between the trigger and the rodent, providing a controlled killing method that is safer for children and pets compared to direct snap traps. The housing acts as an intermediary barrier that shields users from sight of the dead rodent and contains sanitation issues.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If an enclosure-type trap with guillotine mechanism is used, then the dead rodent is concealed, but the trap footprint is large and not suitable for tight quarters

Engineering Contradiction:
Improveconcealment of dead rodentVSAvoidtrap footprint
Core Design Contradiction:
Object-affected harmful factorsVSArea of stationary object

Solution Approach 1:

The guillotine mechanism is nested within the housing enclosure, with the killing mechanism compactly integrated into the trap body. The trigger mechanism and other components are arranged to fit within the enclosed space, maximizing concealment while minimizing overall footprint.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The trap utilizes vertical space efficiently by positioning the guillotine mechanism and housing in a compact three-dimensional arrangement. The pathway is designed to guide the rodent through a limited space while maintaining the enclosed concealment feature.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

3Ease of manufacture

If a disposable trap is used, then the trap is simple to manufacture, but it is not reusable and less economical

Engineering Contradiction:
Improvesimplicity of constructionVSAvoidreusability and economy
Core Design Contradiction:
Ease of manufactureVSProductivity

Solution Approach 1:

The trap design allows for recovery and reuse of the housing and mechanical components. The removable disposal door enables easy cleaning and disposal of the rodent without damaging the main trap structure, allowing the trap to be reused multiple times economically.

Inventive Principle:
Principle #34Discarding and recovering

Solution Approach 2:

The trap is designed to maintain its functional integrity across multiple use cycles. The durable construction and removable disposal mechanism enable continuous reuse, eliminating the need to discard and replace the entire trap after each use.

Inventive Principle:
Principle #20Continuity of useful action

4Productivity

If the trap is made reusable, then it is more economical, but the complexity of manufacture and structure increases

Engineering Contradiction:
ImprovereusabilityVSAvoidstructural complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The trap is segmented into a reusable housing and mechanism assembly and a removable disposal door. This segmentation allows the complex reusable components to be manufactured separately and assembled, simplifying the manufacturing process while enabling reuse.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing and mechanical components are designed with universal features that allow them to be reused across multiple trap cycles. The standardized design of the disposal door and housing interface enables easy assembly and disassembly for cleaning and disposal without requiring complex tools or procedures.

Inventive Principle:
Principle #6Universality (Multi-functionality)
