Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current roof construction methods using mortar are inefficient due to heavy load, long construction time, high costs, short lifespan, and difficulty in repairing leaks, as well as inadequate ventilation leading to dampness and tile decay.
Innovation Solution
A high elongation ridge ventilation sheet using fully dry construction with composite aluminum membranes and butyl adhesive tapes for sloping roofs, allowing air convection and reducing roof load, comprising folded composite aluminum membranes with PET polyester and aluminum layers, and a coated composite membrane with circular holes for improved durability and versatility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If mortar construction is used for ridge tiles, then the ridge structure is stable and solid, but the roof load increases and construction time is extended
Solution Approach 1:
The invention extracts and removes the cement mortar from the ridge construction system, replacing it with a dry assembly method using ridge tiles that interlock mechanically without requiring mortar bonding, thereby eliminating the weight and construction time associated with mortar application
Solution Approach 2:
The invention replaces the chemical bonding mechanism of mortar with a mechanical interlocking system where ridge tiles feature specific geometric shapes and protrusions that fit into corresponding recesses in the batten tiles, providing stability through mechanical means rather than adhesive bonding
2Stability of the object's composition
If mortar is used for ridge construction, then the ridge appears solid and complete, but the construction cost increases and construction period is extended
Solution Approach 1:
The ridge tiles are pre-formed with integrated interlocking features and ventilation channels during manufacturing, eliminating the need for on-site mortar application and curing time, allowing for rapid assembly and reducing construction period while maintaining complete ridge structure
Solution Approach 2:
The ridge tiles are available in various colors and finishes that can match different roof styles, providing aesthetic completeness without requiring additional mortar work or painting, thereby reducing construction time while maintaining visual completeness
3Stability of the object's composition
If ridge is packed solidly with cement mortar, then the ridge structure is sealed, but damp air cannot discharge and batten tiles decay quickly
Solution Approach 1:
The ridge tiles incorporate ventilation channels and porous structures that allow damp air to pass through the ridge assembly, preventing moisture accumulation beneath the roof while maintaining structural integrity, thereby extending batten tile lifespan by eliminating rot-causing moisture
Solution Approach 2:
The invention removes the impermeable mortar layer that trapped moisture, replacing it with ventilated ridge tiles that actively channel damp air outward, transforming the ridge from a sealed barrier to a moisture-extruding system that protects underlying materials
4Stability of the object's composition
If mortar construction is used, then the ridge tiles are firmly attached, but the roof is tainted by mortar and difficult to clean
Solution Approach 1:
The invention completely removes mortar from the ridge assembly process, eliminating the source of mortar stains and associated cleaning requirements, while maintaining firm tile attachment through mechanical interlocking features built into the tile geometry
5Stability of the object's composition
If mortar construction is used, then the ridge structure is continuous, but repair is costly and difficult when leakage occurs
Solution Approach 1:
The ridge assembly is segmented into discrete, modular ridge tiles that can be individually removed and replaced without affecting adjacent sections, allowing for easy localization and repair of leakage points by simply replacing the affected tile rather than repairing entire continuous mortar joints

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution results in a longer-lasting, cost-effective, and aesthetically pleasing roof with enhanced energy savings and reduced leakage risks by facilitating air circulation and eliminating the need for cement mortar.
Implementation Method 1
a butyl adhesive tape for central linking coated on a curved line of either side of the polyurethane layer of the coated composite aluminum membrane, the butyl adhesive tape for central linking being bonded with the PET polyester membrane of one of the folded composite aluminum membranes
Implementation Method 2
a hot melt adhesive for a polyester nonwoven fabric is arranged to connect with each of the folded composite aluminum membranes, with the polyester nonwoven fabric covering the whole coated composite aluminum membrane
Implementation Method 3
air circulating with convection in a true sense under the roof, taking out extra dampness and heat

AI summary
A high elongation ridge ventilation sheet for a sloping roof, having a coated composite aluminum membrane with multiple circular holes, each side of the coated composite aluminum membrane being bonded respectively with a folded composite aluminum membrane via a butyl adhesive tape for central linking, on a side of each folded composite aluminum membrane adjacent the coated composite aluminum membrane is arranged with a hot melt adhesive for connecting a polyester nonwoven fabric with each folded composite aluminum membrane, with the polyester nonwoven fabric covering the whole coated composite aluminum membrane. Further, a fabricating method therefor that realizes wholly dry construction; ridge ventilation sheets adopted on ridge locations not only make the whole roof prettier, but more importantly, enable air convection under the roof in a true sense, taking out extra dampness and heat, resulting in better energy saving effects, and extending life span for the roof.
