Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cell potential detection devices do not effectively prevent leakage of culture solution, which is crucial for maintaining the integrity of cell measurements.
Innovation Solution
A cell potential detection device is designed with a cell potential detection chip, a substrate, and a layered structure comprising a first member for sealing the electrical connection and a second member forming a liquid-storage portion to store culture solution, thereby preventing leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a polystyrene frame is used to store culture solution, then the culture solution can be contained, but the culture solution leaks
Solution Approach 1:
The sealing structure is divided into two distinct members: a first member that seals the electrical connection and a second member that forms the liquid-storage portion. This segmentation allows each member to perform its specific function optimally - the first member provides reliable sealing for electrical components while the second member provides culture solution storage, eliminating the leakage problem that occurred when a single polystyrene frame attempted to perform both functions
Solution Approach 2:
The invention uses composite sealing structure combining a first member (which may be made of sealing material such as resin) and a second member (which forms the liquid-storage portion). This composite approach allows the sealing structure to integrate both electrical connection sealing and culture solution storage functions with complementary material properties, preventing leakage while maintaining electrical integrity
2Reliability
If separate sealing and storage components are used, then leakage is prevented, but the number of components increases
Solution Approach 1:
The first member and second member are integrated into a unified sealing structure that performs both electrical connection sealing and culture solution storage functions. While the structure is segmented into two functional members, they work together as a single integrated component system, avoiding the need for multiple separate components and assemblies, thus preventing leakage without significantly increasing device complexity
3Ease of manufacture
If traditional sealing methods are used, then manufacturing is simple, but culture solution leakage occurs
Solution Approach 1:
The first member is configured to seal the electrical connection before the second member is added to form the liquid-storage portion. This preliminary sealing action ensures that electrical components are protected from culture solution before storage functionality is added, preventing leakage while maintaining a relatively simple manufacturing process where components are added in a predetermined sequence

AI summary
The present disclosure relates to a cell potential detection device, a method of manufacturing the cell potential detection device, and an information processing system that enable prevention of culture solution for a cell from leaking. The cell potential detection device includes: a cell potential detection chip including an electrode unit that detects potential of a cell; a substrate on which the cell potential detection chip is implemented; a first member sealing a connection electrically connecting the cell potential detection chip and the substrate; and a second member layered on the first member, the second member forming a liquid-storage portion that stores culture solution for the cell, together with the first member. The present technology can be applied to, for example, a semiconductor module in which packaged is a chip that detects the potential at an action-potential source point due to a chemical change of a cell.
