Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screen devices require complex and costly methods to couple beams, often necessitating external fastening means that are aesthetically undesirable and laborious, making them unsuitable for DIY installations.
Innovation Solution
The use of coupling pieces with mounting cavities and screw channels allows for easy and secure beam coupling without external fastening, enabling one-person assembly and aesthetic coordination, reducing the need for multiple persons and minimizing labor and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If external fastening means such as angle sections and bolts are used to couple beams, then the beams can be securely fastened, but the aesthetic appearance deteriorates due to visible fastening means
Solution Approach 1:
The patent removes the visible external fastening means (angle sections and bolts) from the exterior of the beam coupling. The fastening function is extracted and relocated to internal mounting cavities within the beam structure, where fastening elements are hidden from view. This allows the beams to be securely coupled while maintaining clean aesthetic lines without external brackets or visible hardware.
Solution Approach 2:
The patent implements nesting by placing mounting cavities and fastening elements inside the beam structure itself. The coupling mechanism is nested within the beam's internal geometry, with mounting cavities formed inside the beam bodies and fastening elements positioned within these cavities. This nested arrangement conceals the fastening means while maintaining structural integrity and aesthetic appearance.
2Strength
If complex fastening methods with multiple fastening means are used to couple beams, then the coupling strength is improved, but the device complexity and labor requirements increase
Solution Approach 1:
The patent merges multiple fastening functions into a single integrated coupling system. Instead of using separate angle sections, multiple bolts, and additional support elements, the invention combines the coupling and fastening functions into beam-mounted coupling pieces with integrated mounting cavities. This unified approach reduces the number of discrete components and simplifies the overall fastening system while maintaining adequate coupling strength.
Solution Approach 2:
The coupling pieces mounted on the beams serve multiple functions simultaneously: they provide structural support, enable beam coupling, and conceal fastening elements. The mounting cavities within the beams serve both as structural features and as housings for the fastening mechanism. This multi-functionality reduces the need for separate dedicated fastening components.
3Strength
If beams are welded or bolted together in workshops to form large construction elements, then the structural integrity is improved, but the ease of transportation and on-site assembly deteriorates
Solution Approach 1:
The patent divides the screen device into separate beam components that can be manufactured and transported independently. Instead of assembling large pre-welded framework sections in workshops, the invention uses individual beams with integrated coupling pieces that can be easily transported to the installation site and assembled on-site through simple mounting operations within the mounting cavities.
Solution Approach 2:
The coupling pieces are pre-mounted onto the beams during manufacturing, creating beams with built-in coupling capability. This preliminary action eliminates the need for complex on-site welding or bolting operations. During installation, workers simply need to position the beams and secure them within the pre-formed mounting cavities, significantly simplifying on-site assembly while maintaining structural integrity.
