Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If frames are manufactured by machining from solid metal, then mechanical robustness and tightness are improved, but material loss and manufacturing cost increase significantly
Solution Approach 1:
The frame is divided into multiple individual frame parts that are joined together to form the complete frame structure. This segmentation allows each part to be manufactured separately with minimal material waste, while the assembly maintains the required tightness through proper joining techniques and sealing compounds.
Solution Approach 2:
The frame construction combines multiple materials including metal frame parts, sealing compounds filled in through-holes, and adhesive substances. This composite approach allows the use of less material overall while maintaining structural integrity and tightness, reducing the material loss associated with machining solid metal blocks.
2Loss of substance
If frames are manufactured by die-casting or injection molding, then material loss is reduced, but tooling costs and manufacturing complexity increase for small series production
Solution Approach 1:
By segmenting the frame into separate parts that can be manufactured using simple cutting processes, the invention avoids the need for complex die-casting or injection molding tools, making the process suitable for small series production while still reducing material waste.
Solution Approach 2:
The manufacturing approach changes from high-precision molding processes to simpler cutting and joining processes, altering the manufacturing parameters to better suit small batch production economics while achieving similar material efficiency.
3Strength
If frame parts are joined by welding or soldering, then structural strength is improved, but post-processing and manufacturing cost increase
Solution Approach 1:
Sealing compounds and adhesive substances serve as intermediary materials between the frame parts, providing both sealing functionality and bonding strength. This eliminates the need for complex welding or soldering processes while maintaining joint integrity and reducing post-processing requirements.
Solution Approach 2:
The invention replaces mechanical joining methods like welding and soldering with chemical bonding using adhesive substances and sealing compounds, simplifying the manufacturing process while maintaining adequate joint strength for the application.
4Ease of manufacture
If traditional frame designs are used, then manufacturing simplicity is maintained, but tightness and hygiene requirements for industrial applications are not met
Solution Approach 1:
The invention extracts the sealing function from the traditional frame structure by introducing dedicated through-holes filled with sealing compounds. This separation of functions allows the frame parts to be simple to manufacture while the sealing system ensures industrial-grade tightness and hygiene compliance.
Solution Approach 2:
Sealing compounds act as intermediary substances that bridge the gaps between frame parts, providing the necessary impermeability for industrial applications while allowing the frame structure itself to remain simple and easy to manufacture.
