Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single tank scale is used for weighing both fine materials and heavy solvents, then device complexity is reduced, but measurement precision deteriorates due to additional loads from process pipes affecting fine material weighing
Solution Approach 1:
The patent segments the weighing function into two independent parts: a tank scale for heavy solvents and a separate weighing module for fine materials. This segmentation allows each weighing device to be optimized for its specific function, preventing the additional loads from process pipes from affecting the precision of fine material weighing while maintaining simple overall device configuration.
2Measurement precision
If multiple tank scales with different capacities are used to weigh fine materials and heavy solvents separately, then measurement precision is improved, but device complexity increases and requires manual operation
Solution Approach 1:
The patent merges the tank scale and weighing module into an integrated system where the weighing module is installed at the bottom of the material tank. This combination allows both heavy solvents and fine materials to be weighed using a single integrated device, eliminating the need for multiple separate scales while maintaining measurement precision through the specialized design of the weighing module that compensates for additional loads from process pipes.
Solution Approach 2:
The patent introduces a compensation mechanism that actively counteracts the additional loads from process pipes. The compensation device applies opposing forces to balance the extra weights from pipes, feed bins, and other external factors, thereby maintaining high measurement precision for fine materials even when using a single integrated weighing system.
3Device complexity
If manual weight addition is used for scale adjustment, then device complexity is reduced, but loss of time increases and risk of cross-contamination occurs
Solution Approach 1:
The patent replaces the manual mechanical adjustment method with an automated electronic compensation system. The compensation device is controlled electronically and can automatically adjust to compensate for additional loads from process pipes, eliminating the need for manual weight addition. This substitution significantly reduces adjustment time and eliminates the risk of cross-contamination while introducing controlled device complexity through the automated system.
