Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connectors are used to connect spacer bar segments, then the spacer bar can be assembled to match the insulating glass unit circumference, but the number of leakage points increases and sealing performance deteriorates
Solution Approach 1:
The spacer bar is divided into multiple segments that can be connected through insertion holes. Each segment contains desiccant, and the segmentation allows the spacer bar to adapt to different circumferences while maintaining sealing through the insertion connection method that minimizes leakage points
Solution Approach 2:
Desiccant is pre-filled into the spacer bar segments before assembly. This preliminary action ensures that the desiccant is already in position and the segments are ready for connection, reducing the need for additional connectors and minimizing leakage points while maintaining adaptability to different circumferences
2Ease of manufacture
If molecular sieve is filled after spacer bar assembly, then the filling process can be completed, but the molecular sieve is exposed to air and absorbs moisture, reducing its adsorption capacity
Solution Approach 1:
The desiccant is pre-filled into the spacer bar segments before assembly and sealing. This preliminary action prevents the desiccant from being exposed to air during the assembly process, maintaining its adsorption capacity while still allowing for a complete filling process
Solution Approach 2:
The filling operation is extracted from the post-assembly stage and performed separately before assembly. This separates the filling process from the exposure to air, allowing the desiccant to be filled and sealed without moisture contamination
3Manufacturing precision
If manual processing and auxiliary equipment are used for spacer bar cutting and bending, then the spacer bar can be processed to fit the insulating glass unit, but production efficiency decreases and labor intensity increases
Solution Approach 1:
The spacer bar is segmented with pre-defined insertion holes at regular intervals. This segmentation allows for standardized cutting and bending operations that can be easily automated, improving both precision and productivity by reducing manual intervention
Solution Approach 2:
The design incorporates standardized insertion hole positions and segment lengths that can be adjusted by changing production parameters rather than manual measurements. This allows automated equipment to achieve high precision processing while maintaining flexibility for different insulating glass unit sizes
4Ease of manufacture
If plastic connectors are used to connect spacer bar segments, then the connection can be achieved, but the connectors are not resistant to aging and may soften at high temperature
Solution Approach 1:
The connector component is extracted and replaced by the spacer bar segments themselves forming the connection through insertion holes. This eliminates the need for separate plastic connectors that are susceptible to aging and heat softening, while maintaining ease of connection through the insertion method
Solution Approach 2:
The connection structure uses composite construction where spacer bar segments with integrated desiccant material connect through insertion holes. This composite design provides both the connection function and resistance to aging and high temperature without requiring separate connector materials
5Strength
If steel connectors are used to connect spacer bar segments, then the connection strength can be achieved, but the connectors are difficult to connect and have high cost
Solution Approach 1:
The separate connector component is extracted and replaced by the spacer bar segments forming their own connection structure through insertion holes. This eliminates the need for expensive steel connectors that are difficult to install, while maintaining connection strength through the integrated segment design
Solution Approach 2:
The spacer bar segments perform their own connection function through the insertion hole mechanism, without requiring separate steel connectors. This self-service approach provides sufficient connection strength while greatly simplifying the manufacturing and assembly process
