Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing exhaust stacks require separate support structures during maintenance, which can be cumbersome and inefficient.
Innovation Solution
A lattice tower structure composed of galvanized steel rods, featuring a triangular configuration with stack supports that can be assembled around existing exhaust stacks, allowing for secure and efficient support during maintenance or repairs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate support tower is used to support the exhaust stack during maintenance, then the exhaust stack can be supported, but the device complexity and ease of operation deteriorate due to the need for additional structures
Solution Approach 1:
The patent combines the exhaust stack support function directly into the lattice tower structure by integrating stack supports with the tower legs. The stack supports are welded to the lattice tower legs at multiple locations, merging the support function into the existing structure rather than requiring a separate support tower, thereby reducing device complexity while maintaining support capability
Solution Approach 2:
The lattice tower structure is designed to serve multiple functions: it provides structural support for the exhaust stack during normal operation and continues to provide support during maintenance operations. The integrated stack supports enable the same structure to fulfill both operational and maintenance support requirements, eliminating the need for additional dedicated support structures
2Reliability
If a separate support tower is used during maintenance, then support is provided, but the ease of operation worsens due to cumbersome assembly and disassembly requirements
Solution Approach 1:
The stack supports are pre-integrated into the lattice tower structure during manufacturing, with support points positioned at multiple locations along the tower legs. This preliminary integration eliminates the need for on-site assembly of separate support structures during maintenance, improving ease of operation while maintaining support stability
Solution Approach 2:
The lattice tower structure acts as an intermediary between the ground and the exhaust stack, providing continuous support during both operation and maintenance. The integrated stack supports serve as intermediaries that transfer loads from the stack to the tower structure, eliminating the need for additional intermediary support structures during maintenance operations
3Strength
If the exhaust stack is supported by machinery, then support is provided, but adaptability worsens when maintenance is required
Solution Approach 1:
The support system is segmented into multiple discrete stack supports distributed along the lattice tower legs. These segmented supports can independently engage with the exhaust stack at different locations, providing adaptability for maintenance operations while collectively providing the necessary support strength through their combined structural contribution

AI summary
A lattice tower structure includes a first lattice section that comprises a first leg, a second leg, and a third leg forming a triangular shaped first lattice section of the tower, the first, second and third leg each constructed of a solid galvanized steel rod; and an exhaust stack at least partially secured within the first, second and third leg.
