Solution Overview

Problem

Despite advanced safety features, medical sharps disposal containers continue to pose hazards due to overfilling, leading to injuries as healthcare workers and non-professionals are not always aware when a container is full, causing obstruction of safety mechanisms and potential exposure to sharp objects.

Innovation Solution

A sensing system integrated with the sharps disposal container that detects the position of the door and generates an alarm signal when the container is full, providing auditory and visual warnings to indicate when the container needs to be changed, using proximity elements and sensing units to ensure timely intervention.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional sharps disposal containers are used without sensing systems, then the device complexity is low, but the reliability is poor due to overfilling hazards and lack of full status indication

Engineering Contradiction:
Improvesafety against overfillingVSAvoidcontainer system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces mechanical full-status indication methods (such as visual indicators on doors or manual checking) with an electronic sensing system that uses sensors to detect door position and container full status. This substitution provides more reliable and automated detection while reducing the need for complex mechanical indicator mechanisms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The sensing system provides feedback about the container's full status to users through alarms or indicators. This feedback mechanism ensures that users are aware when the container is full and needs replacement, preventing overfilling hazards and improving safety without requiring complex manual monitoring systems.

Inventive Principle:
Principle #23Feedback

2Reliability

If automatic mechanical full indication is implemented, then the reliability improves, but the device complexity increases due to additional sensing and alarm mechanisms

Engineering Contradiction:
Improvefull status detection accuracyVSAvoidsensing system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The sensing system automatically detects the container's full status and generates alarms without requiring manual intervention or complex user-operated mechanisms. The system serves itself by autonomously monitoring its own state and providing warnings, which improves reliability while keeping the operational complexity manageable.

Inventive Principle:
Principle #25Self-service

3Object-affected harmful factors

If the container door is designed to prevent complete access to the interior, then the safety against sharp exposure improves, but the ease of operation deteriorates due to restricted access for disposal

Engineering Contradiction:
Improveexposure to sharp objectsVSAvoidsharp disposal convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The door mechanism is segmented into multiple positions: an open position for easy disposal access, a closed position for safety protection, and intermediate positions that allow controlled access. This segmentation enables the door to provide both ease of operation during disposal and safety protection during storage, resolving the contradiction between accessibility and safety.

Inventive Principle:
Principle #1Segmentation
