Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current articular administration methods for joint infiltrations are invasive, require frequent professional intervention, lack precision in dosage adjustment, and result in short-term pain relief, necessitating frequent hospital visits and increased risk of infection due to sterilization challenges.
Innovation Solution
A wearable articular administration device with a reservoir, pump, and control unit that allows for precise and adjustable delivery of active ingredients directly to joints, enabling sustained release through a programmable pump and flexible cannula, eliminating the need for constant professional intervention and minimizing infection risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If manual infiltration by health care professionals using common syringes is used, then the procedure can be performed with simple equipment, but the infiltration duration is short and requires frequent repeated procedures
Solution Approach 1:
The device segments the infiltration process into multiple controlled deliveries of active ingredient over time. Instead of a single manual injection, the system divides the treatment into sequential dosing events, extending the duration of therapeutic effect while maintaining manageable device complexity through modular pump and reservoir design
Solution Approach 2:
The device enables continuous or repeated administration of the active ingredient over an extended period through automated pump control. The system maintains therapeutic presence in the joint cavity through scheduled deliveries, eliminating the interruption and short duration inherent in manual single-injection methods
2Ease of operation
If infiltration is performed periodically by trained health care professionals, then precise dosage can be administered manually, but frequent hospital visits are required increasing patient burden
Solution Approach 1:
The device enables self-service administration where the patient can perform infiltrations independently without requiring trained health care professionals for each procedure. The automated pump system with pre-programmed dosing schedules allows the patient to self-administer precise doses at home, eliminating the need for frequent hospital visits and reducing time loss while maintaining dosage precision
Solution Approach 2:
The device replaces the manual mechanical injection process with an automated electromechanical pump system. This substitution transfers the complex dosing control from the health care professional's manual operation to an automated control unit, simplifying the operation for the patient while maintaining precise dosage delivery
3Measurement precision
If common syringes with varying needles are used for infiltration, then different dosages can be administered, but dosage adjustment precision is difficult and relies on visual estimation
Solution Approach 1:
The device incorporates feedback mechanisms through sensors that monitor the actual dosage delivered and the control unit that tracks cumulative administration. This feedback system ensures precise dosage control by verifying each delivery against the prescribed regimen, enabling accurate dosage adjustment without relying on visual estimation while keeping the device manageable through integrated electronic monitoring
4Reliability
If multiple infiltrations are performed with high dosages, then therapeutic effect can be achieved, but adverse effects on the patient increase
Solution Approach 1:
The device dynamically adjusts the dosage administration through programmable pump control that can modify delivery parameters based on treatment progress and patient response. Instead of static high-dose repeated injections, the system enables adaptive dosing that maintains therapeutic effectiveness while progressively optimizing the regimen to minimize adverse effects through controlled, variable delivery schedules
