Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct gluing is used to attach the vibration membrane to the support structure, then the connection is secure, but the production process becomes complex and inefficient
Solution Approach 1:
The patent replaces the chemical bonding system (gluing) with a mechanical bonding system (thermal molding). The vibration membrane blank is thermally molded directly onto the support structure, creating a mechanical interlocking connection that eliminates the need for separate gluing steps, thereby improving production efficiency while maintaining connection security
Solution Approach 2:
The patent combines the attachment process with the membrane formation process. The thermal molding operation simultaneously forms the vibration membrane blank and attaches it to the support structure in a single integrated step, eliminating the separate gluing step and improving production efficiency
2Reliability
If direct gluing is used to attach the vibration membrane, then the membrane is fixed, but the production process is time-consuming and complex
Solution Approach 1:
The patent merges the membrane formation and attachment operations into a single thermal molding process. The vibration membrane blank is formed and attached to the support structure simultaneously, eliminating the separate gluing step and reducing production time while ensuring reliable membrane fixation
Solution Approach 2:
The patent replaces the time-consuming chemical gluing process with a faster thermal molding process. The heat and pressure applied during thermal molding quickly form and secure the membrane in place, significantly reducing production time while maintaining fixation reliability
3Reliability
If gluing process is used, then the vibration membrane is secured, but environmental pollution increases
Solution Approach 1:
The patent replaces the chemical gluing process with a physical thermal molding process. This substitution eliminates the use of gluing agents and associated volatile organic compounds, reducing environmental pollution while maintaining reliable membrane securing through mechanical interlocking
Solution Approach 2:
The patent converts the potential harm of chemical gluing agents into a beneficial environmental outcome by using thermal molding instead. The heat and pressure that would otherwise require chemical adhesives are used directly to form and secure the membrane, eliminating pollution while achieving the same securing function
