Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing blood glucose monitoring systems face challenges in stable coupling and decoupling operations between the applicator and body-attachable unit, complicating manufacturing and component management, and limiting design flexibility and product diversification.
Innovation Solution
A sensor applicator assembly with a housing comprising an upper and lower frame, featuring a recess portion and a plunger with a fixing hook, allows for stable coupling and decoupling by engaging and disengaging with a recess portion on the body-attachable unit, facilitated by an elastic member providing an elastic force for disengagement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If various elements are used for coupling and decoupling between applicator and body-attachable unit, then coupling functionality is achieved, but device complexity increases and manufacturing becomes difficult
Solution Approach 1:
The coupling mechanism is divided into separate functional elements: a coupling protrusion on the applicator and a corresponding coupling recess on the body-attachable unit. This segmentation allows each component to be manufactured independently with simpler processes while ensuring reliable coupling when assembled.
Solution Approach 2:
The coupling protrusion and recess are designed as universal interfaces that can be applied across different models and variations of the blood glucose monitoring system. This universal design simplifies manufacturing by using standardized components and enables easy product diversification without redesigning the coupling mechanism.
2Reliability
If complicated configurations are used for body-attachable unit and applicator, then coupling functionality is achieved, but ease of manufacture deteriorates
Solution Approach 1:
The complex coupling functionality is extracted into a dedicated coupling protrusion element on the applicator and a corresponding recess on the body-attachable unit. This extraction allows the main body of each component to be manufactured using simpler, more cost-effective processes while the coupling elements provide the necessary attachment stability.
Solution Approach 2:
The coupling mechanism uses simple geometric parameters (protrusion height, recess depth, diameter dimensions) that can be easily controlled during manufacturing. By optimizing these parameters rather than using complex geometries, the invention achieves reliable attachment while maintaining ease of manufacture.
3Adaptability or versatility
If shapes and positions of various elements are changed for design modifications, then adaptability is improved, but device complexity increases
Solution Approach 1:
The coupling protrusion and recess are designed as universal interfaces that remain consistent across different product models. This universality allows design modifications in other areas of the device without affecting the coupling mechanism, providing design flexibility while maintaining simplicity in the coupling system.
Solution Approach 2:
The coupling elements are designed in advance with standardized dimensions and geometries that accommodate various design requirements. This preliminary design approach allows for easy adaptation to different applications by simply modifying non-coupling aspects of the device while keeping the coupling mechanism unchanged.
