Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional junction box inserts use elaborate designs to accommodate flexible fiber optic cables in limited wall spaces, then the installation can be completed, but the device complexity and manufacturing cost increase
Solution Approach 1:
The socket insert is divided into separate functional components: a mounting plate for attachment to the junction box, a drum for cable winding, and a coupling device for optical connectors. This segmentation allows each component to be optimized independently and simplifies the overall installation process by making the modular assembly straightforward.
Solution Approach 2:
The drum is positioned to project axially from the mounting plate, utilizing the axial dimension to provide cable winding space without increasing the radial footprint. This dimensional arrangement allows flexible cable storage within the constraints of limited wall space while maintaining a compact profile.
2Ease of operation
If conventional junction box inserts use elaborate designs to accommodate flexible fiber optic cables, then the installation can be completed, but the manufacturing cost increases
Solution Approach 1:
By segmenting the socket insert into distinct modular components (mounting plate, drum, coupling device), each part can be manufactured separately using cost-effective processes and then assembled. This reduces manufacturing complexity and allows for standardized production of individual components, lowering overall manufacturing costs.
Solution Approach 2:
The mounting plate is designed as a thin-walled, two-dimensional structure that can be formed and stamped from sheet metal. This thin-film approach reduces material usage and manufacturing complexity compared to three-dimensional robust structures, while still providing sufficient mechanical support and mounting functionality.
3Adaptability or versatility
If the drum is detachably operatively connectable to the mounting plate and/or coupling device, then flexibility and ease of installation are improved, but the device complexity increases
Solution Approach 1:
The drum is designed with detachable operative connections that allow it to be selectively attached to the mounting plate and/or coupling device. This dynamic connection system enables the drum to be positioned in different circumferential orientations and easily removed or reattached during installation, providing flexibility without requiring complex permanent integration.
