Solution Overview
Problem
Existing magnetically-inductive flow meters require multiple assembly steps for the field system and front body, which complicates the production process and increases the risk of errors.
Innovation Solution
A magnetically-inductive flow meter design where the front body and coil arrangement carrier are formed monolithically, allowing for a single assembly step by integrating the field system within the housing and using a contacting body arrangement to simplify the connection of coil wires to the operating circuit, which can be achieved through an injection-molding process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the field system and front body are assembled in separate steps, then the manufacturing process is more flexible, but the number of assembly steps increases and production complexity increases
Solution Approach 1:
The patent merges the field system and front body into a single monolithic component formed by injection molding. The coil arrangement carrier and front body are integrated into one piece, eliminating the need for separate assembly steps. This reduces assembly complexity while maintaining manufacturing flexibility through the injection molding process.
2Ease of operation
If multiple assembly steps are used for the field system, then component adjustment is easier, but the risk of assembly errors increases and production time increases
Solution Approach 1:
By forming the field system as a monolithic component, the patent eliminates multiple assembly steps that could introduce errors. The integrated design ensures proper alignment and positioning of all field system components without requiring manual assembly, thereby reducing assembly error risk while maintaining manufacturing efficiency.
3Ease of repair
If the field system components are separately assembled, then replacement and repair is easier, but the stability and reliability of the field system decreases
Solution Approach 1:
The patent creates a stable and reliable field system by forming all components as a single monolithic piece. This integrated structure eliminates potential instability from multiple assembly interfaces and connections, ensuring consistent electromagnetic field generation throughout the operational life of the flow meter.
4Manufacturing precision
If separate assembly steps are used for the field system and front body, then quality control is easier, but production efficiency decreases
Solution Approach 1:
The patent achieves both quality control and production efficiency by forming the field system and front body as a single monolithic component through injection molding. This eliminates multiple assembly steps that would reduce production efficiency, while the controlled molding process maintains high manufacturing precision and quality standards.
