Stretchable Noise-Making Assembly for Pet Toys
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional noise-making elements in pet toys do not effectively produce crackling sounds during active tugging play, lacking a mechanism to enhance engagement through sound and vibration when stretched or pulled.
Innovation Solution
A self-recovering stretchable element with noise-making elements mechanically coupled at attachment points, forming slack portions that flatten and emit noise when extended, combined with travel limiting elements to manage the extended position, using materials like plant-based paper, acetate paper, or polymers, and constructed in various forms such as single-layer or woven configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional noise-making elements (rattlers, bells, squeakers) are used in pet toys, then the toys can produce sounds, but they fail to produce effective crackling sounds during active tugging play when stretched or pulled
Solution Approach 1:
The noise-making element is designed to transition between different states (slack when relaxed, flattened when extended) based on the dynamic action of tugging play. The element dynamically changes its configuration in response to the force applied during play, enabling crackling sounds only during active engagement.
Solution Approach 2:
The physical state of the noise-making element changes from a slack, loose configuration to a flattened, taut configuration when stretched. This parameter change in shape and density enables the element to produce crackling sounds during extension while remaining silent when at rest.
2Reliability
If noise-making elements are attached along the stretchable element, then crackling sounds can be produced during extension, but the structure becomes more complex
Solution Approach 1:
The noise-making element is divided into multiple segments or sections, each attached at different points along the stretchable element. This segmentation allows the element to produce crackling sounds at multiple locations during extension while maintaining a relatively simple overall structure.
Solution Approach 2:
The noise-making element is merged with the stretchable element itself, combining the structural support function with the noise-making function into a single integrated component rather than separate attached parts.
3Ease of operation
If the stretchable element extends fully to produce noise, then engagement is enhanced, but the element may exceed safe limits or become damaged
Solution Approach 1:
The travel limiting element is pre-configured to engage before the stretchable element reaches a damaging extension. This preliminary action prevents over-extension by establishing a mechanical stop at a safe limit.
Solution Approach 2:
The travel limiting element acts as an intermediary between the stretchable element and the potential for damage. It mediates the extension process by providing a mechanical constraint that prevents the element from exceeding safe limits.

Function Achieved in This Case
The solution enables the production of crackling sounds and vibrations during play, enhancing engagement by producing noise when the toy is stretched, twisted, or pulled, providing an active tugging experience for pets and children.
Implementation Method 1
a self-recovering stretchable element
Implementation Method 2
Crackling elements provide a crackling, crinkling or rustling sound and a small vibration when deformed
