Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional fastening systems are used to connect clean room wall elements, then the connection can be achieved, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The fastening system is divided into separate modular components: a fastening element with a head portion and a latching element, and a holding profile with a receiving portion. These segmented components can be independently manufactured, assembled, and disassembled, enabling quick assembly and adaptation while reducing overall system complexity.
Solution Approach 2:
The latching element is designed to be received within the receiving portion of the holding profile, creating a nested structure. The latching element fits into the receiving portion and can be securely positioned, providing a compact and space-efficient connection that simplifies the overall fastening system.
2Reliability
If conventional connection methods are used for clean room wall elements, then structural stability can be achieved, but assembly and disassembly require significant time and effort
Solution Approach 1:
The fastening element and holding profile are pre-designed with complementary geometries that enable immediate form-fitting connection upon assembly. The head portion of the fastening element is shaped to match the receiving portion of the holding profile, allowing the components to self-align and connect quickly without requiring complex adjustment or additional fastening steps.
Solution Approach 2:
The latching element incorporates a movable latch arm that can transition between engaged and disengaged positions. This dynamic component allows for quick latching during assembly and equally quick release during disassembly, enabling the connection to be made and broken rapidly while maintaining structural stability when engaged.
3Adaptability or versatility
If clean room wall elements are designed for adaptability, then modifications can be made easily, but maintaining airtight seals becomes more difficult
Solution Approach 1:
The sealing function is merged directly into the fastening element by applying a sealing coating to the head portion. This integration ensures that the sealing action occurs simultaneously with the mechanical fastening action, maintaining the airtight seal regardless of configuration changes. The sealing coating is applied in the region where the head portion contacts the holding profile, combining structural and sealing functions in one component.
Solution Approach 2:
The sealing coating material properties are specifically selected to provide effective sealing under the contact pressure generated by the form-fitting connection. The coating's elastic and adhesive parameters are optimized to maintain sealing effectiveness while allowing for the dynamic engagement and disengagement of the fastening system, enabling adaptability without compromising seal integrity.
4Reliability
If multiple components are used to ensure airtight sealing, then sealing reliability improves, but assembly complexity increases
Solution Approach 1:
The sealing function is merged directly into the fastening element by applying a sealing coating to the head portion. This integration eliminates the need for separate sealing components such as gaskets or seals, reducing the total number of parts while maintaining or improving sealing reliability. The sealing coating becomes an integral part of the fastening mechanism.
Solution Approach 2:
The fastening element is created as a composite structure by applying a sealing coating material onto the head portion. This composite construction combines the mechanical strength of the fastening element base material with the sealing properties of the coating material, achieving both structural and sealing functions in a single integrated component rather than requiring multiple separate parts.
