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

VSEngineering 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

Engineering Contradiction:
Improveon-site assembly capabilityVSAvoidbonding quality
Core Design Contradiction:
Ease of operationVSReliability

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).

Inventive Principle:
Principle #1Segmentation

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

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

Engineering Contradiction:
Improvepositioning precisionVSAvoidconnection structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

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.

Inventive Principle:
Principle #5Merging (Combining)

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.

Inventive Principle:
Principle #6Universality (Multi-functionality)

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

Engineering Contradiction:
Improvebonding qualityVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #1Segmentation
