Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual code entry or code card insertion is used to adjust measurement parameters, then measurement accuracy can be maintained across different batches, but user error increases and ease of operation deteriorates
Solution Approach 1:
The biosensor automatically provides its identification information through the conductive loop impedance characteristics, eliminating the need for users to manually enter codes or insert code cards. The system self-identifies through its electrical properties, resolving the contradiction between measurement accuracy and ease of operation.
Solution Approach 2:
The patent replaces manual mechanical operations (keyboard entry, code card insertion) with automatic electrical detection. The measurement device reads the biosensor's identity through electrical impedance measurement of conductive loops, substituting mechanical user actions with automated electrical sensing.
2Measurement precision
If manual code entry is required to compensate for batch variations, then measurement accuracy can be maintained, but user error increases leading to safety risks
Solution Approach 1:
The biosensor automatically communicates its batch-specific identification through the conductive loop impedance, eliminating reliance on user actions. This self-identification mechanism ensures that the correct measurement parameters are always applied, removing the source of user error and improving reliability.
Solution Approach 2:
The measurement device receives feedback from the biosensor through the impedance characteristics of the conductive loops. This feedback provides automatic identification information that enables the device to select appropriate measurement parameters, ensuring accurate and reliable measurements without user intervention.
3Measurement precision
If codes are manually entered or code cards inserted for each measurement, then batch-specific parameters can be applied, but time is lost and productivity decreases
Solution Approach 1:
The biosensor automatically provides its identification information through impedance characteristics, eliminating the time-consuming manual processes of code entry or code card insertion. This self-identification enables immediate parameter selection and faster measurement execution.
Solution Approach 2:
The patent replaces time-consuming manual operations with rapid electrical impedance measurement. The automatic reading of conductive loop characteristics occurs instantaneously upon connection, eliminating the time loss associated with manual code input and significantly improving productivity.
