Pet Leash Tension Alert System with Escalating Multi-Sensory Warnings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet pulling devices do not effectively prevent humans from falling over when walking with pets that suddenly move or run, particularly posing a risk to elderly or children.
Innovation Solution
A method and device that detect tension data values in pet pulling leashes, triggering alert modes based on preset thresholds, including indicator lights, vibrations, and sounds to alert humans of increasing tension levels, with escalating intensity from security to alarm to danger levels, and sending an ultrasound alarm to deter pets at high tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pet pulling device provides only simple pulling function, then the device complexity is low, but it cannot alert humans when pets suddenly move or run causing fall risks
Solution Approach 1:
The pet pulling device is transformed from a single-function pulling tool to a multi-functional safety system. The handle incorporates tension sensing capabilities, processing units, and multiple alerting mechanisms (lights, vibrations, sounds) to provide both pulling and safety monitoring functions, resolving the contradiction between simplicity and safety.
Solution Approach 2:
The patent introduces an intermediary processing unit that acts as a mediator between the tension sensor and alerting mechanisms. This processing unit analyzes tension data and triggers appropriate alerts, enabling safety functionality without requiring direct complex integration between all components.
2Reliability
If the alert system uses multiple alert modes with increasing intensity, then the effectiveness of alerting is improved, but the device complexity increases
Solution Approach 1:
The alert system is segmented into three distinct alert modes with increasing intensity: first alert mode (visual light), second alert mode (visual + vibration), and third alert mode (visual + vibration + sound). This segmentation allows the system to provide graduated responses to tension levels, improving alert effectiveness while managing complexity through modular design.
Solution Approach 2:
The alert system dynamically adjusts its response based on detected tension levels. The processing unit selects appropriate alert modes dynamically, escalating from gentle visual cues to more intense multi-sensory alerts as tension increases, making the system adaptive rather than static.
3Measurement precision
If the device monitors tension continuously with multiple thresholds, then the precision of safety monitoring is improved, but the loss of energy increases
Solution Approach 1:
The system uses partial monitoring action by implementing threshold-based detection rather than continuous full-scale analysis. The processing unit only triggers alert modes when tension exceeds predefined thresholds, avoiding constant high-energy alert operations while maintaining precise monitoring capability when needed.

Function Achieved in This Case
The solution effectively alerts humans to potential falls by increasing alert intensity as leash tension increases, preventing injuries from sudden pet movements and running.
