Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fittings for mounting furniture components, doors, or windows on support structures are technically complex, leading to difficult assembly and increased risk of incorrect operation.
Innovation Solution
A fastening device with a first component featuring an unthreaded section and a second component with a mating thread, allowing for quick and tool-free assembly by sliding and pivoting movements, and optionally enhanced by adhesive points or additional fixing means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a complex fastening device design is used, then the fitting provides sufficient strength and reliability, but the assembly process becomes difficult and time-consuming
Solution Approach 1:
The fastening device is divided into two separate components: a first component with a threaded section and an unthreaded section, and a second component with a mating thread. This segmentation allows for a simplified assembly process where the components can be quickly joined by sliding and pivoting movements, while still providing sufficient fastening security through the threaded engagement.
Solution Approach 2:
The unthreaded section is positioned adjacent to the mating thread in the disassembled state, pre-aligning the components for easy assembly. The threaded section is designed with a specific geometry that guides the mating thread during the pivoting movement, ensuring proper engagement without requiring complex alignment procedures.
2Reliability
If a complex fastening device design is used, then the fitting provides sufficient strength and reliability, but the assembly process requires tools and technical expertise
Solution Approach 1:
The fastening device is designed to be self-assembling through simple sliding and pivoting movements of the two components. The threaded section and mating thread are configured such that the assembly process can be completed without tools or specialized technical knowledge, making the fitting easy to manufacture and install while maintaining reliable fastening security.
3Ease of operation
If a simple fastening device design is used, then the assembly process is simplified, but the fitting security and reliability are reduced
Solution Approach 1:
The fastening device is divided into two separate components: a first component with a threaded section and an unthreaded section, and a second component with a mating thread. This segmentation allows for a simplified assembly process where the components can be quickly joined by sliding and pivoting movements, while still providing sufficient fastening security through the threaded engagement.
Solution Approach 2:
The fastening device combines different structural elements (threaded section, unthreaded section, mating thread) in a composite design that integrates both simplicity and security. The threaded portion provides reliable fastening, while the unthreaded section and pivoting mechanism enable easy assembly, creating a composite solution that addresses both requirements simultaneously.
4Reliability
If traditional threaded fastening is used throughout, then the fitting security is maintained, but the assembly time increases significantly
Solution Approach 1:
The unthreaded section is positioned adjacent to the mating thread in the disassembled state, pre-aligning the components for easy assembly. The threaded section is designed with a specific geometry that guides the mating thread during the pivoting movement, ensuring proper engagement without requiring complex alignment procedures or time-consuming operations.
Solution Approach 2:
The fastening device incorporates a dynamic assembly process with two distinct phases: a sliding movement that quickly brings the components together, followed by a pivoting movement that engages the threaded sections. This dynamic approach significantly reduces assembly time compared to traditional static threaded fastening, while maintaining fastening security through the threaded engagement.
