Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If transmitting device uses traditional housing with multiple components and fasteners, then structural stability is improved, but device size and assembly complexity increase
Solution Approach 1:
The patent integrates the light source unit and optical device into a single housing structure, merging multiple components into one integrated unit. This reduces the number of separate parts and fasteners while maintaining structural stability through the unified housing design.
Solution Approach 2:
The housing serves multiple functions simultaneously: it provides structural support, houses the light source unit, accommodates the optical device, and enables automated assembly through its design features. This multi-functionality reduces the need for separate structural components.
2Stability of the object's composition
If transmitting device uses traditional housing with multiple components, then structural stability is improved, but assembly time increases
Solution Approach 1:
The light source unit and optical device are pre-assembled within the housing structure before final installation. This preliminary assembly allows for standardized production and reduces on-site assembly time, as the housing comes ready-configured with its components.
Solution Approach 2:
By combining multiple components into a single housing unit, the patent reduces the number of assembly steps required. The integrated design allows the entire assembly to be installed as one unit rather than requiring sequential assembly of multiple separate components.
3Strength
If transmitting device uses traditional housing design, then component support is improved, but weight increases
Solution Approach 1:
The patent eliminates the need for separate support structures by integrating component mounting directly into the housing. This merger removes redundant support elements and fasteners, reducing overall weight while maintaining adequate component support through the housing's structural design.
4Extent of automation
If transmitting device uses integrated housing design, then assembly automation is improved, but manufacturing precision requirements increase
Solution Approach 1:
The housing is designed with standardized features that serve multiple purposes: structural support, component positioning, and alignment reference for automated assembly. This universal design enables automation while managing precision requirements through integrated reference features.
