Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional permanent parapet installation is used on ceiling or floor structures, then the parapet can be securely attached, but the installation requires precise work, involves numerous loose parts, and is labor-intensive
Solution Approach 1:
The patent combines multiple separate components (parapet body, attachment elements, reinforcement structures) into a single pre-assembled parapet unit. This merging eliminates the need to handle numerous loose parts during installation, reducing installation complexity and labor requirements while maintaining secure attachment capability.
Solution Approach 2:
The parapet is pre-assembled and pre-configured with all necessary attachment elements and reinforcement structures before delivery to the construction site. This preliminary preparation includes pre-attached mounting brackets, embedded reinforcement bars, and pre-configured adjustment mechanisms, allowing for rapid installation without complex on-site assembly.
2Reliability
If traditional parapet installation is used, then the parapet can be securely attached, but the installation process is labor-intensive and time-consuming
Solution Approach 1:
By integrating the attachment elements, reinforcement structures, and adjustment mechanisms into the parapet body itself, the patent enables a single installation action that simultaneously achieves secure attachment and proper positioning, dramatically improving installation efficiency without compromising attachment reliability.
Solution Approach 2:
All attachment-preparatory actions are performed during factory assembly, including welding of reinforcement bars, pre-attachment of mounting brackets, and pre-configuration of adjustment mechanisms. This transfers complexity from the installation phase to the manufacturing phase, enabling rapid on-site installation while maintaining secure attachment.
