Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If bolting coupling is used to connect radome and lower case, then connection strength is improved, but water penetration occurs due to play in bolting holes
Solution Approach 1:
The connection structure is segmented into multiple functional elements: locking units for mechanical interlocking, sealing protrusions for creating sealing interfaces, and fasteners for securing. This segmentation allows each element to perform its specific function optimally without compromising hermetic sealing.
Solution Approach 2:
Sealing protrusions act as intermediary elements between the radome and lower case, creating a sealing interface that prevents water penetration while maintaining connection strength. The sealing protrusions fill the gap that would otherwise allow water ingress through bolting holes.
2Strength
If excessive tightening is applied during bolting, then connection strength is improved, but deformation occurs in the radome
Solution Approach 1:
The locking units are designed with dynamic characteristics that allow them to engage and lock at optimal positions without requiring excessive tightening force. The mechanical interlocking mechanism naturally limits the tightening force to prevent radome deformation while ensuring adequate connection strength.
Solution Approach 2:
The locking units provide self-limiting tightening through their mechanical interlocking design. Once engaged, the locking units automatically prevent further tightening that would cause deformation, eliminating the need for precise operator control and preventing radome damage.
3Strength
If multiple bolts are directly bolted by operator, then connection strength is improved, but assembly process becomes cumbersome
Solution Approach 1:
Multiple locking functions are merged into integrated locking units that combine positioning, locking, and sealing features. This consolidation reduces the number of separate components and simplifies the assembly process while maintaining connection strength.
Solution Approach 2:
The locking units are designed for self-alignment and self-assembly, eliminating the need for precise manual positioning and complex assembly procedures. The units automatically engage in the correct position, making the assembly process straightforward while ensuring adequate connection strength.
4Strength
If bolting area is included in radome design, then connection strength is improved, but space utilization deteriorates and weight increases
Solution Approach 1:
The locking units are designed as thin, integrated features that can be formed directly into the radome structure or lower case, minimizing the additional material required. This approach maintains connection strength while preserving space utilization and avoiding unnecessary weight increase.
Solution Approach 2:
The locking units serve multiple functions: mechanical interlocking for connection strength, sealing interface for hermetic sealing, and space-efficient design. This multi-functionality eliminates the need for separate bolting areas, maximizing space utilization while maintaining adequate connection strength.
