Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of weighing apparatuses face difficulty in adjusting filter characteristics and sensitivity for disturbance vibration detection, requiring skilled personnel to set up the system effectively, which increases operational burden.
Innovation Solution
The weighing apparatus includes a processing unit that determines whether to use the original vibration signal based on both original signals during non-load weighing conditions, allowing automatic selection and reducing the need for manual adjustments, with options for operator input and comparison of signal standard deviations to choose the most suitable filtering configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If filter characteristics and sensitivity are adjusted manually by skilled personnel, then weighing performance is optimized, but operator burden and setup complexity increase
Solution Approach 1:
The weighing apparatus automatically determines whether to use vibration signal correction without requiring manual configuration by skilled personnel. The system self-adjusts by acquiring vibration signals during non-load weighing, analyzing their characteristics, and autonomously deciding on correction application, thereby optimizing weighing performance while eliminating the need for expert setup.
Solution Approach 2:
The system dynamically changes the parameter of vibration signal correction application based on analyzed characteristics. By monitoring vibration signal properties during non-load weighing and automatically adjusting whether correction is applied, the system adapts to different operational conditions without manual intervention, resolving the contradiction between optimized performance and ease of operation.
2Ease of operation
If automatic determination of vibration signal usage is implemented, then ease of operation improves, but system complexity increases
Solution Approach 1:
The system performs preliminary analysis during non-load weighing by acquiring and analyzing vibration signals before actual weighing operations. This preliminary action allows the processing unit to pre-determine the appropriate correction strategy, simplifying subsequent operations while managing complexity through structured advance preparation rather than complex real-time decision-making.
