Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the installation unit uses a complex structure with multiple components, then the reliability of sensor insertion is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The installation unit is divided into distinct functional modules: a housing containing the analyte detection device, a parallel slider module with auxiliary needle, and a triggering module. These modules are connected through buckle mechanisms that allow controlled relative movement. This segmentation enables each module to perform its specific function independently while maintaining overall system reliability.
Solution Approach 2:
The patent combines multiple functions into integrated components. The housing both protects the analyte detection device and provides the structural framework for the buckle connection system. The parallel slider module integrates the auxiliary needle mechanism with the release mechanism, eliminating the need for separate components and simplifying the overall structure while maintaining reliability.
2Reliability
If the installation unit uses a complex structure with multiple components, then the reliability of sensor insertion is improved, but the ease of operation deteriorates
Solution Approach 1:
The first and second buckles are pre-configured in a coupled state before use, with the elastic module already under tension. When the triggering module is actuated, the pre-loaded elastic energy automatically drives the release mechanism and guides the parallel slider module through the insertion motion. This preliminary configuration eliminates the need for users to manually coordinate multiple steps, making operation simple while ensuring reliable sensor insertion.
Solution Approach 2:
The elastic module provides self-powered motion for the parallel slider module during installation. After the buckles are released by the triggering module, the elastic force automatically propels the auxiliary needle and sensor into the skin without requiring additional manual force from the user. The system serves itself by converting stored elastic energy into the mechanical work needed for reliable insertion.
3Reliability
If the installation unit uses traditional complex mechanisms, then the reliability of connection is improved, but the manufacturing cost increases
Solution Approach 1:
The installation unit is designed as a disposable device where the housing, parallel slider module, and auxiliary needle are intended for single use. This approach allows the use of simpler, less durable materials and manufacturing methods compared to reusable devices. The buckle connection mechanism uses basic plastic clips and elastic bands that are inexpensive to manufacture, reducing production costs while maintaining sufficient connection reliability for the intended single-use application.
