Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable fluid dispensers are prone to cross-contamination and leakage, and require frequent retrieval and storage, which can lead to contamination and reduced efficacy of the sanitizing fluid.
Innovation Solution
A multifunctional wearable fluid dispensing apparatus with a rotatable nozzle and electric pump assembly that automatically dispenses fluid upon detected action, using a removable cartridge and integrated sensors for precise fluid delivery, reducing the need for manual handling and minimizing contamination risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional wearable fluid dispensers are used, then portability and accessibility are improved, but cross-contamination and leakage risks increase
Solution Approach 1:
The patent replaces manual mechanical dispensing with an automated electric pump system controlled by sensors. The pump assembly delivers fluid through a nozzle without requiring user contact with the fluid reservoir, eliminating cross-contamination while maintaining portability in a wearable device.
Solution Approach 2:
The patent introduces an intermediary automated dispensing system between the user and the sanitizing fluid. The sensor-detect-actuate mechanism serves as a mediator that delivers fluid without direct user contact, preventing contamination while preserving the convenience of wearable portability.
2Device complexity
If manual handling of fluid dispensers is required, then device simplicity is improved, but fluid wastage and contamination increase
Solution Approach 1:
The patent implements a feedback control system where sensors detect user actions (such as hand presence or specific gestures) and automatically trigger the pump to dispense the precise amount of fluid needed. This closed-loop control prevents both over-dispensing and under-dispensing, eliminating fluid wastage while maintaining system simplicity through automated control.
Solution Approach 2:
The wearable device performs self-service by automatically detecting when dispensing is needed and executing the dispensing action without user intervention. The sensor-pump-nozzle system autonomously manages fluid delivery, preventing contamination and wastage that would result from manual handling.
3Object-affected harmful factors
If automated sensor-actuated dispensing is implemented, then cross-contamination is reduced, but device complexity increases
Solution Approach 1:
The patent integrates multiple functions into a single compact wearable device: the housing serves as both structural support and fluid reservoir containment, the electric pump assembly provides both fluid delivery and pressure control, and the sensor system performs both detection and triggering functions. This multi-functionality reduces the number of separate components needed, managing device complexity while achieving automated contamination-free dispensing.
