Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lock portion is loosened to change the solid sample, then the solid sample can be exchanged, but the liquid sample leaks between the members
Solution Approach 1:
The measurement jig is divided into separable members (first member, second member, third member) that can be independently removed and reassembled. The cell is integrated with one member to form an interchangeable unit, allowing sample exchange without disassembling the entire assembly and preventing liquid leakage.
Solution Approach 2:
The cell containing the liquid sample and solid sample is integrated within one of the members (second member), creating a nested structure where the cell is housed inside the member. This allows the entire member-cell assembly to be removed and reattached as a unit, preventing liquid leakage during sample exchange.
2Ease of manufacture
If the anode plate and cathode plate are removed for plating, then the plating can be performed, but the operation becomes complicated
Solution Approach 1:
The anode plate and cathode plate are extracted as separate, removable components from the bottom wall assembly. This allows them to be independently removed for plating treatment and then reinstalled, simplifying the plating process while maintaining operational simplicity through standardized reattachment procedures.
Solution Approach 2:
The anode plate and cathode plate are pre-installed on the bottom wall in a standardized configuration with predetermined positions and orientations. This preliminary arrangement allows for quick removal and reinstallation during plating operations, reducing operational complexity by eliminating the need for complex alignment procedures.

Implementation Method 1
a first lock portion having an arm shape, the other end of which is pivotally supported by end portions of the first holding wall and end portions of the second holding wall, one end of which includes a fitting portion, and elastically presses the middle block toward the bottom wall
Implementation Method 2
a second lock portion that presses an upper member toward the bottom wall to integrate the frame, the lower block, the cell, the middle block, and the upper member
Implementation Method 3
The electrophoretic mobility measuring device radiates light to a sample to which the electric field is applied, and detects light scattered by the sample with a light receiver
Implementation Method 4
an anode plate and a cathode plate for applying an electric field to the sample
