Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw connection is used to connect the electrode to the potentiostat, then a secure electrical connection is achieved, but the assembly process becomes time-consuming and error-prone due to polarity verification requirements
Solution Approach 1:
The connector automatically verifies polarity through its internal structure: the spring element can only engage with the thread when the connector is inserted in the correct orientation, and the spring contact pins automatically establish electrical contacts with the corresponding terminals. This self-verifying mechanism eliminates the need for manual polarity checking and prevents incorrect assembly.
Solution Approach 2:
The spring element acts as an intermediary between the thread and the connector housing. It engages the thread to provide mechanical locking while allowing the connector to be pushed on without threading, thus mediating between the need for secure connection and ease of assembly.
2Reliability
If a screw connection is used to connect the electrode to the potentiostat, then a secure electrical connection is achieved, but the risk of incorrect polarity and subsequent damage increases
Solution Approach 1:
The connector design incorporates preliminary anti-action by structurally preventing incorrect polarity connection before damage can occur. The spring element's engagement with the thread and the positioning of spring contact pins create a mechanical barrier that only allows correct orientation, eliminating the possibility of reverse polarity damage before it can happen.
3Productivity
If a plug connection is used instead of screw connection, then assembly time is reduced and polarity errors are eliminated, but the mechanical locking strength may be compromised
Solution Approach 1:
The spring element is pre-loaded with spring force that automatically engages with the thread when the connector is pushed on. This preliminary action of spring compression and subsequent engagement provides mechanical locking without requiring the user to perform threading actions, thus maintaining both speed and strength.
4Strength
If multiple threaded connections and nuts are used on the electrode fastening element, then a secure mechanical connection is achieved, but the complexity and error-proneness of assembly increases
Solution Approach 1:
The invention merges multiple functions into a single connector component: mechanical locking (via spring element engaging the thread), electrical connection (via spring contact pins), and polarity verification (via structural design) are all integrated into one piece that is pushed on in a single action, eliminating the need for separate nuts and multiple connection steps.
