Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If gold leaf thickness is reduced to 0.1μm or thinner, then the cost decreases, but the surface becomes sparse and holes are formed
Solution Approach 1:
The patent applies parameter changes by controlling the thickness of gold leaf within a specific range (0.1-0.2μm) and adjusting processing parameters such as aqueous solution composition and ultrasonic treatment conditions to achieve both cost-effectiveness and surface integrity. This resolves the contradiction by finding optimal parameter values that balance thickness reduction with maintaining surface quality.
2Reliability
If gold leaf thickness is increased to reduce holes, then the cost increases, but economic problems occur
Solution Approach 1:
The patent optimizes the gold leaf thickness parameter to a specific range (0.1-0.2μm) that provides sufficient surface integrity while minimizing gold consumption and cost. This parameter optimization resolves the contradiction between surface quality and economic cost.
3Strength
If bonding pressure is increased to strengthen attachment, then damage or deformation occurs during handling, but handling difficulty increases
Solution Approach 1:
The patent introduces an aqueous solution as an intermediary medium that facilitates the separation of gold leaf from base material and subsequent attachment to new base material. This intermediary approach enables handling and reattachment without requiring strong bonding that would cause deformation, resolving the contradiction between bonding strength and handling ease.
4Stability of the object's composition
If gold leaf is attached to base material for stability, then separation becomes difficult, but separation is needed for processing
Solution Approach 1:
The patent uses aqueous solution as an intermediary that enables easy separation of gold leaf from base material through dissolution or detachment, while still allowing stable attachment when needed. This intermediary mechanism resolves the contradiction between maintaining attachment stability and enabling easy separation for processing.
5Manufacturing precision
If expensive sputtering equipment is used to produce gold film, then gold leaf quality improves, but equipment cost and process complexity increase
Solution Approach 1:
The patent employs a simpler, more economical approach to gold leaf production that avoids expensive sputtering equipment. By using alternative methods such as handling pre-produced gold leaf fabric and processing it through aqueous solution treatment and ultrasonic separation, the patent achieves the required quality without complex equipment, resolving the contradiction between manufacturing precision and device complexity.
