Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sensor implantation devices for chronic disease monitoring are cumbersome to assemble, costly to produce, and can cause discomfort due to complex manufacturing processes and inadequate sterilization, leading to pain during implantation.
Innovation Solution
An air-tight desiccating container with a housing, implanting module, detachable module, and desiccating element that maintains a dry environment for the sensor, allowing for seamless implantation into the subcutaneous portion of a living body with reduced steps and pain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the sensor and implanter are separately produced and assembled, then the manufacturing process is simpler, but the manufacturing cost increases and user convenience decreases
Solution Approach 1:
The patent combines the sensor and implanter into a single integrated device. The sensor is pre-assembled with the implanter housing, needle assembly, and control electronics before final sterilization. This integration eliminates the need for separate assembly steps by the user, reducing complexity while maintaining manufacturing efficiency through modular sub-assembly processes.
2Reliability
If the sensor is sealed in a container with desiccant, then the sensor remains dry and sterile, but the container structure becomes more complex and costly
Solution Approach 1:
The patent employs a nested container structure where the sensor is sealed within an inner sterile barrier, which is then placed inside an outer container containing desiccant material. This nested approach maintains sensor dryness and sterility while optimizing space utilization and reducing overall structural complexity compared to separate containment systems.
3Reliability
If the implantation process is divided into needle implantation and needle extraction steps, then the sensor can be implanted, but the process takes longer and causes more discomfort
Solution Approach 1:
The patent performs preliminary actions by pre-assembling the sensor with the implanter housing and pre-sterilizing the entire integrated unit before use. The needle is pre-loaded and positioned within the housing, eliminating the need for separate needle implantation and extraction steps during actual use, thereby reducing procedure time and patient discomfort.
4Loss of information
If multiple blood draws are performed for physiological monitoring, then comprehensive data can be obtained, but patient discomfort increases
Solution Approach 1:
The patent extracts the sensing element from the external monitoring system and implants it directly into the patient's subcutaneous tissue. This single implantation provides continuous access to physiological data (blood glucose, cholesterol, etc.) without requiring repeated blood draws, thereby maintaining data completeness while eliminating recurring patient discomfort.

Function Achieved in This Case
The design reduces manufacturing costs, ensures sensor integrity, and provides a hygienic, painless implantation process by maintaining the sensor's effectiveness and user convenience.
