Cable Holding Device with Integrated Fastening for Chimney Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing holding devices for vertical structures like chimneys require complex assembly processes due to numerous nuts and fasteners, leading to prolonged assembly times and potential slipping of non-loaded holding organs, which can cause structural instability under wind and snow loads.
Innovation Solution
The solution involves using sleeves with threaded holes for locking crossbars with breakaway screws, angularly designed fastening elements with comb nails, and interconnected crossbars to simplify assembly and enhance stability, allowing for quicker installation and secure load transfer without the need for multiple types of fasteners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If numerous nuts and fasteners are used to connect crossbars to holding elements, then the structural stability is improved, but the assembly time increases significantly
Solution Approach 1:
The patent combines multiple fastening functions into a single integrated fastening element that simultaneously connects the crossbar to the holding element and provides locking functionality. This merging of functions reduces the number of separate nuts and fasteners needed, thereby decreasing assembly time while maintaining structural stability through the integrated design.
Solution Approach 2:
The fastening elements are pre-configured with integrated locking mechanisms and connection geometries that enable immediate secure attachment upon installation. This preliminary preparation of the fastening components eliminates the need for multiple sequential fastening operations, reducing assembly time while ensuring reliable structural connection from the moment of installation.
2Reliability
If multiple types of fasteners are used to secure holding organs, then the load distribution is improved, but the device complexity increases
Solution Approach 1:
The patent employs a universal fastening element design that can perform multiple fastening functions and adapt to different mounting configurations. This single multi-functional fastener type replaces the need for multiple specialized fastener types, reducing device complexity while maintaining effective load distribution through its versatile connection capabilities.
Solution Approach 2:
The fastening system is segmented into modular components with standardized interfaces that can be configured in various arrangements to distribute loads effectively. This modular segmentation allows the same basic fastener type to be deployed in different patterns and configurations to achieve proper load distribution without requiring multiple types of fasteners.
3Reliability
If numerous fastening points are provided to prevent slipping, then the holding stability is improved, but the assembly complexity increases
Solution Approach 1:
The patent integrates multiple fastening points into a single multi-point fastening element that attaches to several locations simultaneously. This merging of multiple attachment functions into one component achieves the holding stability of numerous fastening points while avoiding the assembly complexity of installing multiple separate fasteners at different locations.
Solution Approach 2:
The fastening elements are pre-configured with multiple attachment points and geometries that enable simultaneous engagement with multiple holding element locations. This preliminary configuration ensures proper holding stability is achieved in a single installation action rather than requiring sequential fastening at multiple points, thereby reducing assembly complexity.
