Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual inspection of alternator assembly conditions often leads to omitted checks and potential work failures, resulting in reduced alternator performance and deterioration.
Innovation Solution
A system and method utilizing a smart box connected to a vehicle's electronic control unit (ECU) to monitor driving data and determine the assembled condition of the alternator, including speed, rpm, throttle position, and voltage differences, with a server to store and display inspection results, and a fixed scanner for vehicle ID confirmation, enabling automatic inspection and warning alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual inspection is used to confirm assembling torque, then worker flexibility is maintained, but inspection confirmation is omitted and work failures occur
Solution Approach 1:
The patent replaces the manual mechanical inspection system with an automated electronic monitoring system. The smart box collects data from vehicle sensors (battery voltage, current, temperature) and automatically analyzes assembly conditions, eliminating the need for manual torque confirmation while improving inspection reliability.
Solution Approach 2:
The inspection system performs self-diagnosis by automatically monitoring its own operational parameters. The smart box continuously collects data from the vehicle's ECU and sensors, automatically determines assembly status, and generates inspection reports without requiring external manual intervention.
2Measurement precision
If automated inspection system is implemented, then inspection accuracy is improved, but system complexity increases
Solution Approach 1:
The smart box serves multiple functions: it collects data from various vehicle sensors, stores inspection data, analyzes assembly conditions, and generates reports. This multi-functional design improves measurement precision while avoiding the complexity of separate dedicated devices for each function.
Solution Approach 2:
The smart box acts as an intermediary between the vehicle's ECU and the inspection system. It collects raw data from the ECU, processes it through predetermined algorithms, and presents analyzed results, simplifying the overall system architecture while maintaining high detection precision.
3Reliability
If manual assembling torque confirmation is performed, then equipment cost is reduced, but alternator performance deteriorates due to omitted inspection
Solution Approach 1:
The inspection system operates continuously throughout the alternator assembly process, constantly monitoring parameters like battery voltage, current, and temperature. This continuous monitoring ensures alternator performance reliability without interrupting the assembly workflow, maintaining high productivity.
Solution Approach 2:
The system performs preliminary inspection by monitoring assembly parameters in real-time during the assembly process itself, rather than conducting separate post-assembly checks. This preliminary detection prevents performance deterioration before it occurs while maintaining efficient production flow.
