Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If sustainable chemistry processes are used to synthesize larger molecules, then atom economy and use of renewable sources are improved, but polyaromatic hydrocarbon content and by-product formation increase
Solution Approach 1:
The patent changes reaction parameters including temperature control, catalyst selection, and reaction time to optimize the balance between atom economy and polyaromatic hydrocarbon formation. Specific parameters are adjusted to favor desired products while minimizing harmful by-products.
Solution Approach 2:
The patent introduces intermediate purification steps and uses intermediary substances to control the reaction pathway, preventing excessive polyaromatic hydrocarbon formation while maintaining good atom economy in sustainable chemistry processes.
2Ease of manufacture
If traditional synthesis processes are used, then manufacturing experience and established protocols are leveraged, but multiple synthesis steps and extensive purification are required
Solution Approach 1:
The patent combines multiple synthesis steps into integrated reaction sequences, merging purification steps with reaction steps, and combining multiple transformations into one-pot processes to reduce the total number of steps while maintaining manufacturing reliability.
Solution Approach 2:
The patent develops universal catalysts and reaction conditions that can be applied across different synthesis pathways, allowing a single process design to handle multiple transformations and reducing the need for specialized steps for each chemical.
3Productivity
If reactions are conducted to produce desired chemicals, then target product yield is achieved, but impurities and suboptimal properties occur in final product
Solution Approach 1:
The patent performs preliminary purification of reactants, pre-optimizes reaction conditions, and uses protective groups or temporary modifications to prevent impurity formation before reactions occur, ensuring both high yield and high purity in the final product.
Solution Approach 2:
The patent converts potentially harmful impurities into useful by-products or redirects reaction pathways to transform unwanted side products into desired compounds, thereby maintaining high productivity while achieving superior product purity.
4Manufacturing precision
If extensive post reaction purification steps are implemented, then product purity is improved, but economic feasibility and process complexity increase
Solution Approach 1:
The patent extracts and removes the need for extensive purification steps by designing reactions that inherently produce minimal impurities, taking out unnecessary intermediate isolation steps, and eliminating complex purification equipment requirements through improved reaction selectivity.
