Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a sacrificial metal framework is used in glass blowing, then the glass product can be formed with unique bubble chambers, but the framework cannot be reused and material waste increases
Solution Approach 1:
The metal framework is divided into multiple modular components including vertical bars, horizontal bars, and corner pieces that can be disconnected and reassembled. This segmentation allows the framework to be taken apart for cleaning and maintenance, enabling repeated use without compromising the formation of unique bubble chamber patterns in the glass products.
Solution Approach 2:
The framework design allows residual glass to be easily removed and discarded from the metal structure after each use. The metal framework itself is recovered and reused for subsequent glass blowing operations, eliminating the need to discard the entire framework after a single use and reducing material waste significantly.
2Manufacturing precision
If a sacrificial metal framework is used, then the glass product achieves desired shape, but production efficiency decreases due to inability to reuse
Solution Approach 1:
The framework transitions from a static sacrificial structure to a dynamic reusable tool. The modular design with connectable and disconnectable components allows the framework to be adapted between uses, maintained when needed, and repeatedly employed for glass blowing, thereby increasing production efficiency while maintaining shape precision.
Solution Approach 2:
The metal framework serves multiple functions: it acts as a forming structure for bubble chambers, a support structure during glass blowing, and a reusable tool for multiple productions. The standardized modular components can potentially be reconfigured for different glass product designs, enhancing the framework's versatility and productivity.
3Productivity
If a reusable metal framework is implemented, then productivity increases through multiple uses, but the complexity of the apparatus increases
Solution Approach 1:
By segmenting the framework into standardized modular components, the complexity is managed through repetition of simple elements rather than one complex monolithic structure. The modules connect through simple joinery, making the overall system easier to understand, assemble, and maintain despite serving multiple production cycles.
4Loss of substance
If residual glass is removed from the framework for reuse, then material waste is reduced, but additional time and steps are required
Solution Approach 1:
The framework design incorporates features that facilitate easy removal of residual glass before the next use. By preparing the framework in advance with accessible surfaces and modular connections, the time required for cleaning and preparation is minimized, making the reuse process more efficient despite the additional step.
