Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bark deterrents that use electric shocks require constant skin contact, leading to potential constriction injuries and are prone to false triggering due to environmental noise interference.
Innovation Solution
A radially contractible wearable structure with radial contraction modules and a driving module that controls the contact of electric shock contacts with the skin, combined with an environmental audio filtering system to reduce false triggering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electric shock contacts remain in constant contact with the pet's skin, then the deterrent effect is maintained, but constriction injuries may occur and the device is prone to false triggering
Solution Approach 1:
The collar employs radial contraction modules that can dynamically change their radial position between expanded and contracted states. The driving module actuates these modules to contract radially inward, bringing electric shock contacts into contact with the pet's skin only when needed for deterrent effect, while expanding outward at other times to prevent constriction injury. This dynamic adjustment resolves the contradiction between maintaining constant deterrent effect and preventing harmful constriction.
2Reliability
If electric shock contacts remain in constant contact with the pet's skin, then the deterrent effect is maintained, but the device is prone to false triggering due to environmental noise interference
Solution Approach 1:
The collar implements periodic contact with the pet's skin through radial contraction modules that are actuated only when barking is detected. The driving module receives control signals to contract the radial modules into contact with the skin, applying electric shock intermittently rather than continuously. This periodic action reduces false triggering by eliminating constant contact while maintaining effective deterrent function when actually needed.
3Object-affected harmful factors
If radial contraction modules are added to enable controllable contact, then constriction injury is prevented, but device complexity increases
Solution Approach 1:
The collar is divided into multiple independent radial contraction modules that can be actuated individually or collectively. Each module contains its own scissor linkage mechanism and contact elements, allowing segmented control of the electric shock contacts around the collar's circumference. This segmentation enables precise control over which contacts engage with the pet's skin, preventing constriction injury while maintaining deterrent effectiveness.
Solution Approach 2:
The driving module serves as an intermediary between the control system and the radial contraction modules. It receives control signals and translates them into mechanical actuation of the radial modules through the scissor linkage mechanisms. This intermediary structure simplifies the overall control architecture while enabling complex radial movement patterns to prevent constriction injury.

Implementation Method 1
the driving module is configured to wind the traction rope to shorten a portion of the traction rope outside the driving module to drive the radial contraction module to switch from the expansion position to the contraction position
Implementation Method 2
the driving module is also configured to release the traction rope to extend the portion of the traction rope outside the driving module to drive the radial contraction module to switch from the contraction position to the expansion position
