Solution Overview
Problem
Existing analyte detection devices are limited in miniaturization due to the shape and size constraints of button batteries, which restricts further design optimization and results in insufficient battery capacity for continuous glucose monitoring in diabetic patients.
Innovation Solution
A battery shell integrated analyte detection device is designed with a transmitter containing a battery cavity that includes a cavity shell, diaphragm, electrolyte, anode plate, cathode plate, and pole ear, along with an electrolyte insulation layer, allowing for a more compact and optimized design that increases battery capacity and reduces volume.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If button battery is used to power the analyte detection device, then the device structure is simple and easy to manufacture, but the device volume is large and battery capacity is limited
Solution Approach 1:
The patent combines the battery shell with the transmitter shell into a single integrated structure. The battery cavity is formed within the transmitter housing, eliminating the need for separate button battery components. This merging approach reduces overall device volume while maintaining manufacturing simplicity through integrated molding processes.
Solution Approach 2:
The battery components (anode, cathode, electrolyte, diaphragm) are nested within the transmitter housing structure. The cavity shell contains all battery elements in a compact arrangement, allowing the battery to be embedded within the overall device footprint rather than adding external volume.
2Ease of manufacture
If button battery is used to power the analyte detection device, then the device structure is simple, but the battery capacity is insufficient for long-term monitoring
Solution Approach 1:
By merging the battery and transmitter shells, the design eliminates wasted space between separate components. This allows for a larger battery capacity to be accommodated within the same overall device volume, providing sufficient power for extended continuous glucose monitoring without requiring multiple button batteries.
Solution Approach 2:
The invention changes the physical parameters of the power source by transitioning from small button batteries to a custom-designed flat battery with optimized dimensions. The battery can be tailored with specific active material quantities and electrode surface areas to achieve the required capacity while maintaining a thin profile suitable for wearable applications.
3Ease of manufacture
If traditional battery design is used, then manufacturing is straightforward, but the device cannot achieve further miniaturization
Solution Approach 1:
The battery is segmented into thin functional layers (anode, cathode, electrolyte, diaphragm) that can be manufactured using roll-to-roll or lamination processes. This layered segmentation allows for precise control of each component's thickness and composition, enabling miniaturization while maintaining manufacturing efficiency through specialized production techniques.
Solution Approach 2:
The battery components utilize flexible thin film structures rather than rigid bulk materials. The electrolyte and electrode layers are formed as thin films that can be laminated together, creating a compact, flexible battery assembly that significantly reduces device volume compared to traditional rigid button battery construction.

AI summary
A battery shell integrated analyte detection device is provided. A battery cavity is arranged within the transmitter, and the cavity shell is integrated with the shell of transmitter. The diaphragm, the electrolyte, the anode plate, the cathode plate and the pole ear are arranged in the cavity shell, the electrolyte insulation layer is also arranged in the cavity shell, to form the highly integrated analyte detection device with battery and transmitter integration, the shape and size of the analyte detection device are no longer limited by the shape and size of the button battery. After the integration of the battery and transmitter, the battery has more available space and smaller occupied volume, which can meet the design requirements of analyte detection device miniaturization.
