Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roof systems face issues with poor construction quality, safety, and wind resistance, particularly at skylights, due to loose connections and deformation under strong wind loads, which are not adequately addressed by existing solutions.
Innovation Solution
A roof system comprising a roof body formed by assembled modules with self-locking components and pressure relief adjustment components on skylights, ensuring stability and wind resistance through cooperative reinforcement and pressure management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If large-span metal roof panels are used to reduce lapping and improve integration, then the roof becomes more aesthetically pleasing and easier to construct, but the connection strength decreases and wind uplift resistance deteriorates
Solution Approach 1:
The roof panel system is divided into multiple segments including upper roof panels, lower roof panels, ridge buckling covers, and connecting pieces. Each segment can be independently manufactured and assembled, allowing for modular construction while maintaining overall structural integrity through multiple connection points
Solution Approach 2:
The ridge buckling cover is nested within the ridge connecting piece structure, with the elastic traction device positioned inside the ridge buckling cover. This nested arrangement allows compact integration of multiple functional components without increasing overall footprint
2Ease of operation
If roof panels are connected mechanically by latching and engaging, then the structure becomes easier to assemble, but the stiffness decreases and deformation increases under wind load
Solution Approach 1:
The elastic traction device is pre-installed within the ridge buckling cover before assembly, and the connecting pieces are pre-configured with engagement features. This preliminary preparation enables quick assembly while ensuring that the structural stiffness requirements are met through pre-positioned reinforcement elements
Solution Approach 2:
The connection system combines mechanical latching components with elastic traction elements, creating a composite connection mechanism that provides both ease of assembly and sufficient structural stiffness to resist deformation under wind loading
3Adaptability or versatility
If skylight is installed at the ridge, then the roof achieves better lighting and ventilation, but the wind resistance deteriorates due to high negative pressure at the highest point
Solution Approach 1:
The elastic traction device and reinforcing connecting pieces are installed in advance to counteract the high negative wind pressure that will act on the ridge skylight. These pre-installed reinforcement elements create preliminary resistance against wind uplift forces before the actual wind load is applied
Solution Approach 2:
The solution addresses the wind resistance problem by adding reinforcement elements in the vertical dimension (elastic traction device inside the ridge buckling cover) and the longitudinal dimension (connecting pieces along the ridge), transforming a two-dimensional skylight installation into a three-dimensional reinforced structure
4Productivity
If aloft work is used for mounting roof panels, then the overall laying can be accomplished, but construction safety deteriorates and accuracy control becomes tricky
Solution Approach 1:
The roof system is segmented into modular panels with standardized connection features, allowing workers to assemble sections in a systematic sequence. This segmentation enables progressive construction from lower to upper sections, improving safety by reducing the need for continuous aloft work while maintaining productivity through efficient modular assembly

AI summary
A roof system is provided. The roof system includes a roof body capable of forming a flat roof or a corrugated roof, where the roof body is provided on a roof pillar; a gutter system is provided at a valley position of the corrugated roof or on the flat roof; a skylight system is further provided at a pitched roof or a ridge of the corrugated roof or on the flat roof; and a pressure relief adjustment component is provided on the skylight system. According to the roof system, a plurality of roof modules are assembled into the roof body. Two adjacent ones of the roof modules are fixed by a connecting plate and a self-locking component when assembled. A plurality of reinforcing points work cooperatively, so the roof system achieves a high utilization rate, and ensures the overall stability and bearing capacity of the roof.
