Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional anchoring systems with additional accessories (plates, screws, nuts) are used to secure tray sections, then the attachment strength is improved, but the device complexity and installation time increase significantly
Solution Approach 1:
The patent merges the anchoring function directly into the tray section structure itself. The transverse metal wires are integrated into the tray design, eliminating the need for separate anchoring accessories like plates, screws, and nuts. This consolidation maintains attachment strength while dramatically reducing device complexity and the number of components required.
Solution Approach 2:
The tray section is designed to be self-anchoring through its own structural elements. The transverse metal wires that form part of the tray section itself serve as the anchoring mechanism, allowing the tray to secure itself to the support structure without requiring additional fastening components or complex assembly procedures.
2Reliability
If traditional anchoring systems requiring precise assembly are used, then the attachment reliability is improved, but the ease of operation deteriorates due to uncomfortable working positions and limited space
Solution Approach 1:
The anchoring system is segmented into modular tray sections with standardized transverse wire positions. Each tray section is independently designed with pre-positioned transverse metal wires that align with corresponding wires on adjacent sections, enabling simple, repeatable assembly without requiring complex alignment procedures or uncomfortable working positions.
Solution Approach 2:
The transverse metal wires are pre-positioned and pre-configured during tray section manufacturing. This preliminary arrangement of anchoring elements eliminates the need for precise field assembly and complex alignment procedures during installation, allowing workers to simply connect pre-prepared sections together in various spatial configurations.
3Device complexity
If tapered tray sections with multiple close transverse wires are used to eliminate additional accessories, then the device complexity is reduced, but the manufacturing complexity and installation time increase due to multiple bends
Solution Approach 1:
The patent employs universal, standardized tray sections with identical transverse wire configurations throughout the system. Rather than using tapered sections with varying wire positions, the same modular tray design can be used in different orientations and configurations, simplifying manufacturing while maintaining the ability to create complex cable routing paths through the arrangement of standardized sections.
4Strength
If traditional anchoring systems are used in confined spaces, then the attachment strength is maintained, but the adaptability to different spatial configurations deteriorates due to required working angles
Solution Approach 1:
The tray section design enables dynamic spatial configuration through the flexible arrangement of standardized transverse wires. The system can adapt to various spatial configurations including tight corners and confined spaces by adjusting the orientation and positioning of modular tray sections, while the transverse wires maintain attachment strength through their integrated design that doesn't require fixed working angles.
