Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional bio-sensing materials are used, then the sensing element can be manufactured with simple structures, but the structures are unstable and orientations are inconsistent leading to poor sensitivity
Solution Approach 1:
The patent introduces a borate-containing linker as an intermediary molecule between the substrate and the sensing molecule. This linker provides stable covalent bonding to the substrate while maintaining consistent spatial orientation for the sensing molecule, thereby improving both structure stability and detection sensitivity simultaneously
Solution Approach 2:
The patent modifies the chemical structure parameters of the sensing element by incorporating borate moieties with specific spatial configurations. This structural parameter change enables consistent molecular orientation and stable attachment, resolving the contradiction between simplicity and performance
2Productivity
If conventional bio-sensing materials are used, then the manufacturing process is simple, but the materials cannot be reused and are not environmentally friendly
Solution Approach 1:
The borate-containing linker enables the sensing material to be regenerated and reused. After the sensing molecule completes its detection function, it can be detached and the linker remains on the substrate for subsequent sensing cycles, achieving reusability without significantly increasing manufacturing complexity
Solution Approach 2:
The stable borate-linker-substrate structure allows the sensing element to maintain its functional capacity across multiple usage cycles. The linker preserves the sensing molecule's activity and enables continuous detection operations, improving productivity while keeping the manufacturing process manageable
3Measurement precision
If conventional bio-sensing materials are used, then the structure is simple, but the orientations of the specimen under test are inconsistent leading to poor sensitivity
Solution Approach 1:
The borate-containing linker acts as a mediating structure that simplifies the overall device architecture while providing precise spatial control. It bridges the gap between the substrate and sensing molecule, ensuring consistent orientation without requiring complex structural arrangements
