Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting wall parts to smooth facades face challenges in achieving weather and aging resistance, safety, and strength requirements, while also requiring quick and easy on-site assembly, especially under adverse conditions like rain, snow, or wind.
Innovation Solution
Integration of turnbuckles into strips allows for quick and stable anchoring of wall parts, utilizing two nuts and a tightening screw for precise positioning, with the option of linear clamping and triangular cross-section strips for predetermined angles, and the use of glass fiber reinforced polyurethane strips for improved bonding in controlled environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional adhesive bonding is used to connect wall parts on site, then assembly can be performed under various conditions, but the bonding quality deteriorates under adverse weather conditions like rain, snow, or wind
Solution Approach 1:
The connection system is segmented into modular components: strips with integrated turnbuckles are pre-installed on wall parts in a controlled environment, then these pre-assembled units are connected on-site using mechanical fastening rather than adhesive bonding. This separates the bonding process (done in controlled conditions) from the assembly process (done on-site).
Solution Approach 2:
The patent replaces the chemical adhesive bonding system with a mechanical connection system using turnbuckles and fasteners. This mechanical system is not affected by adverse weather conditions like rain, snow, or wind, allowing reliable on-site assembly regardless of environmental conditions.
2Manufacturing precision
If turnbuckles with integrated nuts and tightening screws are used to connect wall parts, then positioning precision and connection stability are improved, but device complexity increases
Solution Approach 1:
The turnbuckle mechanism merges multiple functions into a single integrated component: the body provides structural connection, the nuts enable adjustable fastening, and the tightening screw provides precise positioning. This consolidation achieves high positioning precision without proportionally increasing overall system complexity.
Solution Approach 2:
The turnbuckle serves multiple functions simultaneously: it provides mechanical connection between wall parts, enables adjustable positioning through the tightening screw, ensures stable anchoring through the nuts, and allows for tension adjustment. This multi-functionality reduces the need for separate components for each function.
3Reliability
If strips are pre-glued in a controlled environment rather than on site, then bonding quality and weather resistance are improved, but assembly time and process complexity increase
Solution Approach 1:
The strips with turnbuckles are pre-assembled and pre-glued in a controlled manufacturing environment before delivery to the construction site. This preliminary action ensures optimal bonding quality without weather interference and allows parallel preparation of multiple components, reducing overall project time despite adding a pre-assembly step.
Solution Approach 2:
The construction process is segmented into two phases: controlled pre-assembly in the factory and rapid mechanical connection on-site. This segmentation allows the time-consuming bonding process to occur in controlled conditions during manufacturing, while on-site work is limited to quick mechanical fastening, reducing weather-related delays.

AI summary
The device comprises strips (2) made of glass fiber reinforced plastic, which are provided at end sides of the wall portions (1). The elements of tie bars are integrated into the strips, such that mutual anchorage and tensioning of the wall portions are enabled by the tie bars according to the assembly. Each tie bar has two nuts integrated into the strips and a clamping screw (4). The glass panes are provided as wall portions and the strips have a triangular cross section, such that the interconnected wall portions have a predetermined angle with each other.
