Circular Cat Toy with Spring-Actuated Prey Decoy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cat toys are passive and lack interactive mechanisms that can sustain a cat's interest over time, as they are either too simple or prone to becoming lost, failing to provide a dynamic and intellectually stimulating play experience.
Innovation Solution
A circular enclosure with a rotating track and prey decoy that mimics movement, combining a spring mechanism to create an upward and downward motion, encouraging the cat to engage through pawing, and an alternate embodiment featuring a cam-driven up and down motion for multiple decoys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a motorized character assembly is used to create dynamic motion, then the toy becomes more engaging for cats, but the toy can become unconstrained and roll about wide expanses becoming lost
Solution Approach 1:
The toy is segmented into a stationary base structure and a moving prey decoy component. The base contains the motor and drive mechanism, while the prey decoy is the only moving part, constrained to travel along a defined circular track within the base. This segmentation allows dynamic motion where needed while maintaining overall positional stability.
Solution Approach 2:
A circular track acts as an intermediary constraint between the motorized drive mechanism and the prey decoy. The track guides the motion of the prey decoy in a controlled circular path, preventing it from leaving the base while still providing engaging movement for the cat.
2Stability of the object's composition
If a prey decoy travels in a continuous circular path, then the motion is smooth and predictable, but it lacks the dynamic variation that sustains cat interest
Solution Approach 1:
The prey decoy's motion is made dynamic through vertical pop-up movement combined with horizontal circular travel. The spring mechanism causes the prey to periodically rise and fall along the circular track, creating unpredictable motion patterns that vary with each rotation and sustain cat interest.
Solution Approach 2:
The spring mechanism creates periodic vertical motion of the prey decoy as it travels around the circular track. This periodic pop-up action occurs at regular intervals during each rotation, providing rhythmic surprise elements that keep the cat engaged without disrupting the overall circular motion pattern.
3Ease of operation
If the track opening is continuous, then the prey decoy can travel freely around the circle, but it cannot create the upward and downward motion that stimulates cat engagement
Solution Approach 1:
The continuous circular track is segmented by introducing breaks or gaps at specific locations. These breaks allow the spring mechanism to propel the prey decoy upward through the opening, creating vertical motion. The track is thus divided into covered sections that guide horizontal motion and open sections that enable vertical弹出 motion.
Solution Approach 2:
The track design transitions from a purely horizontal two-dimensional path to a three-dimensional trajectory. By incorporating breaks in the track, the prey decoy's motion extends into the vertical dimension, allowing it to pop up and down as it travels around the circle, thereby stimulating cat engagement.

Function Achieved in This Case
The solution provides a durable, inexpensive, and continually challenging play experience that stimulates cats intellectually and physically, enhancing play interaction without the risk of the toy becoming lost.
Implementation Method 1
The prey decoy is further spring urged in a vertical direction, perpendicular to the plane of rotational motion

AI summary
A generally circular enclosure is provided defining a generally circular track about which a prey decoy is located and travels. Openings or apertures in its housing permitting the prey decoy to travel about the track. The prey decoy is secured to a rotating wheel that imparts a rotary motion about the circular shaped track. The prey decoy is further spring urged in a vertical direction, perpendicular to the plane of rotational motion. The track opening has at least one break, making it noncontiguous. As the decoy is deployed about the track and impinges against the housing at the break in the track, the decoy is urged downward, and subsequently is urged upward when it reaches the track opening at the opposing side of the break. This circular motion in which the prey decoy appear to be moving upward and downward as it travels about the circular path stimulates the animal to paw at and engage the prey.
