Pet Immobilizer Vest with Rapid-Inflation Bladder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pet owners face challenges in quickly and effectively restricting a pet's movement during emergencies, such as a dog darting into the road or becoming aggressive at a dog park, as existing methods lack a reliable and rapid solution.
Innovation Solution
A pet immobilizing system comprising a vest with a bladder between the pet's rear legs, coupled with a pressure source that can be rapidly inflated via a wireless signal, using either a gas canister or chemical inflation system, to restrict movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pet restraint device is used to restrict movement, then safety is improved, but the response time to immobilize the pet is too slow
Solution Approach 1:
The bladder is pre-installed in the vest between the pet's legs in an uninflated state, ready for immediate deployment. When activation occurs, the bladder rapidly inflates to restrict movement, eliminating the need for manual assembly or preparation during the emergency situation.
Solution Approach 2:
The system uses a pneumatic bladder that can be rapidly inflated with air or gas to restrict the pet's movement. The bladder expands quickly when pressurized, providing immediate immobilization effect within seconds, thus resolving the contradiction between safety reliability and rapid response time.
2Loss of time
If a rapid inflation system is used to quickly immobilize the pet, then response time is improved, but the device complexity increases
Solution Approach 1:
The inflation mechanism is extracted as a separate, self-contained pressure source (such as a pressurized gas canister or chemical reaction chamber) that can be independently activated. This modular approach allows rapid inflation without requiring complex integrated systems, reducing overall device complexity while maintaining fast response time.
Solution Approach 2:
The system changes the physical state of the bladder from uninflated to inflated by introducing pressurized gas or triggering a chemical reaction. This parameter change (volume expansion) provides rapid immobilization effect without requiring complex mechanical actuation systems, thus improving response time while keeping device complexity manageable.
3Reliability
If a vest with bladder is used to restrict pet movement, then immobilization effectiveness is improved, but the ease of operation for donning and removal is reduced
Solution Approach 1:
The vest is divided into separate components including the front portion, waist portion, and bladder compartment that can be independently assembled and adjusted. This segmentation allows the owner to easily don and remove the vest while ensuring proper positioning of the bladder between the pet's legs for effective immobilization.
Solution Approach 2:
The vest incorporates adjustable straps and connectors that can be dynamically adjusted to fit different pet sizes and shapes. The bladder compartment closure is designed to be easily released when the bladder inflates, allowing the vest to adapt to the immobilization requirement while maintaining ease of operation during normal wear.

AI summary
A pet immobilizing system utilizes a vest to located a bladder between a pet's legs. The bladder is rapidly inflated to hinder the pet's movement or to immobilize the pet. A remote electronic device sends a wireless signal to a wireless signal receiver coupled with the pressure source to activate inflation of the bladder. A pressure source may be canister or chemical inflation pressure source that produces an inflation fluid from the reaction of two or more chemicals, A vest may include a waist portion that extends around the pet's waist. A bladder compartment may be configured in the vest for retaining the bladder. A bladder compartment may have an opening to direct the inflation of the bladder out between the pet's legs. A remote electronic device may be a mobile phone that operates an App with an activation button to initiate inflation of the bladder.
