Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual scooping of fermented liquid products is used, then collection and recycling can be performed, but labor intensity is high and work efficiency is low
Solution Approach 1:
The patent replaces manual mechanical scooping operations with an automated liquid discharge device that uses controlled mechanical movement to scoop and transfer fermented liquid products. The device includes a scoop body connected to a driving mechanism that automatically performs the collection and recycling operations, eliminating manual labor while maintaining operational control.
2Reliability
If manual scooping of fermented liquid products is used, then collection can be performed, but dripping is incomplete and distillation efficiency is influenced
Solution Approach 1:
The patent replaces imprecise manual scooping with a mechanically controlled scoop body that can be precisely positioned and operated. The driving mechanism ensures complete collection of fermented liquid products through controlled movement, preventing incomplete dripping and maintaining distillation efficiency by ensuring all liquid is properly transferred.
3Reliability
If heavy reliance on old pits is used for fermentation, then stable microbial florae can be maintained, but yield increase of high-quality Baijiu is limited
Solution Approach 1:
The patent implements a feedback control system where sensors detect parameters of the fermented liquid products and provide information to the control system. This allows real-time monitoring and adjustment of fermentation conditions, enabling new pits to rapidly develop stable microbial florae while maintaining high-quality product output, thus increasing yield without sacrificing quality.
Solution Approach 2:
The patent uses the fed-batch system to dynamically adjust fermentation parameters such as nutrient supplementation, temperature, and pH control. This enables new pits to quickly establish optimal conditions for microbial flora development, accelerating the maturation process and increasing high-quality Baijiu yield while maintaining microbial stability.
4Productivity
If automated collection and control systems are implemented, then work efficiency is improved and labor intensity is reduced, but device complexity increases
Solution Approach 1:
The patent designs the automated liquid discharge device to perform multiple functions: scooping fermented liquid products, transferring them to storage, and recycling them back to the fermentation pit. The fed-batch system also integrates sensing, control, and parameter adjustment functions. This multi-functionality reduces the need for separate devices and operations, managing system complexity while maximizing work efficiency.
