Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If conventional carbonization method is used to extract amorphous silica from plant materials, then silica can be obtained, but metal ions remain as impurities and purity cannot be increased
Solution Approach 1:
The patent applies preliminary action by performing acid treatment on plant materials before carbonization. The acid solution removes metal ions and other impurities from the raw materials prior to the carbonization process, ensuring that the silica extracted afterward has high purity without metal ion contamination.
Solution Approach 2:
The patent uses acid solution to extract and remove harmful metal ions from plant materials before silica extraction. This preliminary extraction of impurities separates the harmful components from the valuable silica, allowing subsequent processes to produce high-purity amorphous silica.
2Productivity
If conventional silica manufacturing process is used, then amorphous silica can be produced, but the process takes too much time for mass production
Solution Approach 1:
The patent implements continuous processing by combining acid treatment, carbonization, and silica extraction into an integrated workflow. The acid-treated materials are directly carbonized without intermediate drying steps, and the carbonized material proceeds directly to silica extraction, maintaining continuous useful action throughout the process to reduce total manufacturing time.
Solution Approach 2:
The patent merges multiple process steps into a streamlined sequence where acid treatment, carbonization, and silica extraction are combined. By eliminating unnecessary intermediate steps and directly transitioning from one process to the next, the overall manufacturing time is reduced while maintaining product quality.
3Productivity
If conventional drying process is used after soaking plant materials in solution, then materials can be prepared for next step, but production efficiency is reduced due to lengthy drying time
Solution Approach 1:
The patent eliminates the conventional drying step by directly proceeding from acid treatment to carbonization. The acid-treated materials are immediately carbonized without intermediate drying, maintaining continuous useful action and significantly reducing the time loss associated with lengthy drying processes.
