Large Capacity Gutter Alignment and Wind Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gutters lack the capacity to withstand wind pressures on commercial buildings and do not provide an effective alignment tool for installing lower mounting hangers, leading to inaccurate and slow installation processes.
Innovation Solution
A large capacity gutter system that includes a gutter member, top hanger, face support bracket, lower mounting hanger, and Z-bracket, utilizing an alignment tool for precise installation of the lower mounting hanger to prevent upward gutter movement due to wind pressures, featuring a gutter cleat, miter cleat, and splice member for secure attachment, and an alignment bar for accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional gutters are used without alignment tools, then installation is simpler, but installation accuracy and speed deteriorate
Solution Approach 1:
The alignment bar serves as an intermediary tool between the building structure and the lower mounting hanger. It provides reference surfaces that enable precise positioning of the hanger without requiring complex measurement procedures, thus improving installation accuracy while maintaining simplicity
Solution Approach 2:
The alignment bar is installed beforehand on the building to establish precise reference positions for the lower mounting hangers. This preliminary action ensures that when the hangers are installed, they are automatically positioned with high accuracy, eliminating the need for complex real-time measurement during the main installation process
2Productivity
If conventional mounting hangers are used without alignment tools, then installation process is simpler, but installation speed deteriorates
Solution Approach 1:
The alignment bar acts as a mediator that guides the installation of multiple lower mounting hangers in sequence. By providing fixed reference points, it enables installers to quickly and accurately position each hanger without repeated measurements, thereby increasing installation speed while keeping the process straightforward
Solution Approach 2:
By pre-installing the alignment bar with marked positions, the system enables rapid sequential installation of lower mounting hangers. The preliminary positioning references eliminate the need for time-consuming measurements during hanger installation, thus improving productivity without significantly complicating the overall process
3Strength
If standard gutter support structures are used, then structure is simpler, but resistance to wind pressure deteriorates
Solution Approach 1:
The gutter support system is segmented into multiple functional components: upper mounting hangers for primary support, lower mounting hangers with lock lips for secondary anchoring, face support brackets for lateral stability, and Z-brackets for corner reinforcement. This segmentation allows each component to address specific structural requirements, enhancing overall wind pressure resistance while maintaining manageable complexity
Solution Approach 2:
The lower mounting hanger combines multiple functions into a single component: it provides mechanical attachment to the building, incorporates a lock lip to prevent upward movement, and integrates alignment features. This merging of functions into unified components strengthens the structure against wind pressures without proportionally increasing complexity
4Reliability
If lower mounting hanger is installed without preventing upward movement, then installation is easier, but reliability under wind pressure deteriorates
Solution Approach 1:
The lower mounting hanger is designed with a lock lip that protrudes to engage with the gutter's front lip, creating a preliminary anti-action against the upward force generated by wind pressure. This design feature is built into the component itself, providing automatic prevention of upward movement without requiring additional installation steps or complex procedures
Solution Approach 2:
The lock lip mechanism is designed to automatically engage with the gutter front lip when the lower mounting hanger is installed in the correct position. This self-service feature provides inherent protection against upward movement under wind pressure, maintaining reliability while keeping installation simple and intuitive

AI summary
A large capacity gutter includes a gutter member, a top hanger, a face support bracket, a lower mounting hanger, and a Z-bracket. A gutter cleat extends from the gutter member and is inserted into the lower mounting hanger. The top hanger preferably includes an upper building mount member, a lengthwise support member and a gutter support projection. The face support bracket preferably includes an L-building mount member, an L-lengthwise support member and an L-vertical member. The lower mounting hanger includes a lower building mount member, and a lower hook portion. The Z-bracket preferably includes a top member, an angled member, and a bottom member. An alignment bar is used to suspend the lower mounting hanger from the building, so the lower mounting hanger may be fastened to the building. The top hanger, the face support bracket and the Z-bracket are assembled to each other and inserted into the gutter member.
