Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If natural bamboo fiber is obtained by softening bamboo wood and rolling, kneading and combing with a fiber opener, then the production process is simple, but the fibers have different lengths, uneven thickness, low fiber strength, rough shape, high ash content, chemical pollution and are easy to brittle fracture
Solution Approach 1:
The bamboo processing is divided into distinct stages: cutting bamboo into tubes, processing into fiber skins, fermentation treatment, drying, kneading, oiling, and combing. This segmentation allows each stage to optimize specific properties, resulting in uniform fiber length, consistent thickness, and enhanced strength while maintaining processability.
Solution Approach 2:
The patent applies preliminary action through the fermentation treatment step, where bamboo fiber skins are subjected to controlled fermentation before final processing. This preliminary biological action prepares the fiber structure, removing impurities and enhancing fiber quality before mechanical processing, thereby improving strength and reducing brittleness.
2Ease of manufacture
If natural bamboo fiber is obtained by softening bamboo wood and rolling, kneading and combing with a fiber opener, then the production process is simple, but the fibers have rough shape and high ash content in powder
Solution Approach 1:
The multi-stage process segments the transformation of bamboo into fiber, with dedicated steps for processing into fiber skins, fermentation, drying, kneading, and combing. Each stage controls specific parameters to achieve uniform fiber morphology and consistent dimensions, eliminating the rough shape and high ash content associated with simpler methods.
Solution Approach 2:
The patent employs parameter changes throughout the process, particularly in the fermentation stage where temperature, humidity, and duration are controlled to optimize fiber quality. The kneading and oiling stages also involve controlled parameter adjustments to achieve uniform fiber texture and reduce ash content, resulting in precise manufacturing outcomes.
3Productivity
If natural bamboo fiber is obtained by softening bamboo wood and rolling, kneading and combing with a fiber opener, then production is efficient, but the fibers are easy to brittle fracture and have low fiber strength
Solution Approach 1:
The fermentation treatment serves as a preliminary action that biologically prepares the fiber structure before mechanical processing. This preliminary treatment enhances fiber strength and toughness, preventing brittle fracture during subsequent mechanical operations while maintaining production efficiency through automated processing stages.
Solution Approach 2:
The patent introduces intermediary substances and treatments, including fermentation agents and oiling compounds, that mediate between the bamboo raw material and final fiber product. These intermediaries enhance fiber strength and toughness, preventing brittleness while allowing efficient mechanical processing to proceed.
