Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If rigid holding elements are used to maintain pipe position, then structural stability is improved, but sound coupling to the building structure increases
Solution Approach 1:
The patent introduces a bearing ring as an intermediary element between the pipe and the building structure. This bearing ring acts as a mediator that provides stable positioning while preventing direct sound transmission paths. The bearing ring is designed to contact the pipe at multiple bearing points, maintaining positional stability without creating rigid sound bridges to the building structure.
Solution Approach 2:
The invention extracts the sound transmission function from the structural support function. By separating these functions into distinct components (bearing ring for support, fire protection element for containment), the design eliminates the sound coupling that occurs when structural elements directly contact the building framework.
2Strength
If pipe clamps are used to fasten the pipe, then mechanical fixation is improved, but structure-borne sound bridges are created
Solution Approach 1:
The bearing ring serves as an intermediary that provides mechanical fixation without creating sound bridges. Instead of using traditional pipe clamps that directly attach to structural elements, the bearing ring contacts the pipe at multiple points and is contained within the fire protection element, which is then secured to the building opening without direct structural attachment.
Solution Approach 2:
The fire protection element acts as a flexible containment structure that holds the bearing ring and pipe assembly. This element can be made of fire-resistant material that provides containment without rigid structural connection, thereby maintaining mechanical fixation while avoiding sound transmission paths.
3Stability of the object's composition
If stepped holes or sleeves are used in the opening, then pipe positioning is improved, but installation complexity increases
Solution Approach 1:
The bearing ring is designed as a universal component that can be installed in various opening configurations without requiring specialized stepped holes or sleeves. The bearing ring adapts to different opening sizes and shapes, providing consistent pipe positioning functionality across multiple installation scenarios, thereby simplifying the overall installation process.
Solution Approach 2:
The invention segments the pipe support function from the opening modification function. Instead of requiring the opening itself to be modified into complex stepped configurations, the support function is provided by the separate bearing ring component, which can be installed in a simple round opening. This segmentation eliminates the need for complex concrete work while maintaining positioning stability.
4Stability of the object's composition
If fixed bearing points are used in the connection element, then structural stability is improved, but adjustability of pipe position is reduced
Solution Approach 1:
The bearing ring is designed with dynamic characteristics that allow it to adapt to different pipe positions while maintaining stability. The bearing points on the bearing ring can contact different bearing points on the pipe depending on the pipe's position, providing both adjustability and stable support. This dynamic adaptation occurs without requiring active control mechanisms.

Function Achieved in This Case
Enables flexible installation configurations, reduces structural vibrations and sound transmission, and provides effective fire protection by allowing adjustable pipe positioning and decoupling of sound vibrations from the building structure.
Implementation Method 1
a jacket made of an intumescent material. In the event of a fire, this material swells and closes the space between the pipe and the opening
