Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing handle installation method for bathroom equipment is inefficient due to difficulty in aligning threads and lack of quick release and installation capabilities, resulting in time wastage.
Innovation Solution
A quick mountable assembly for handles featuring a tube with convex threads and a nut with corresponding convex inner wall sections, allowing for axial movement and rotational locking, separating the installation process into distinct axial and rotational movements to speed up the installation process without increasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the nut is screwed onto the threaded tube from one end to the other end in a conventional manner, then the installation is firm and reliable, but the installation process is slow and time-consuming
Solution Approach 1:
The tube is divided into two distinct sections: a first peripheral section with smooth surface and a second peripheral section with convex threads. The nut is similarly divided with a first inner wall section and a second inner wall section with convex threads. This segmentation allows the nut to engage with different sections of the tube in sequence, first sliding onto the smooth section for quick positioning, then engaging with the threaded section for secure locking, thus combining speed and reliability.
Solution Approach 2:
The first peripheral section of the tube and the first inner wall section of the nut are designed as smooth sections that allow the nut to be quickly slipped onto the tube and positioned at the correct location before threading engagement. This preliminary positioning action eliminates the time-consuming alignment process of conventional threading, allowing the operator to quickly prepare the assembly before the final secure engagement with the threaded sections.
2Manufacturing precision
If the nut is screwed onto the threaded tube in a slow spiral process, then thread alignment is achieved, but the installation efficiency is low
Solution Approach 1:
By segmenting the tube and nut into smooth and threaded sections, the alignment process is simplified. The smooth first peripheral section and first inner wall section allow the nut to be easily slipped onto the tube and positioned correctly without requiring precise thread alignment from the start. The convex threads on the second sections then naturally guide the final engagement, ensuring proper alignment while maintaining high installation efficiency.
Solution Approach 2:
The smooth first peripheral section serves as a preliminary alignment zone where the nut can be quickly positioned on the tube without the complexity of thread engagement. This preliminary positioning ensures that when the nut is rotated to engage the threaded second peripheral section, the threads are already approximately aligned, reducing the rotational adjustment needed and significantly improving installation efficiency while maintaining precision.
3Ease of manufacture
If a standard nut is used for handle installation, then the cost is low and the installation is firm, but quick release and installation cannot be achieved
Solution Approach 1:
The division of the tube and nut into smooth and threaded sections enables a hybrid engagement mechanism. The smooth first sections allow for quick positioning and release, while the threaded second sections provide firm locking. This segmentation allows the handle assembly to be quickly installed by slipping the nut onto the tube and rotated to engage the threads, and equally quickly released by reversing the process, combining the advantages of both standard nuts and quick-release mechanisms without requiring complex specialized components.
4Strength
If the nut is screwed tightly onto the tube, then a secure connection is achieved, but the installation process is complex and time-consuming
Solution Approach 1:
The segmented design with distinct smooth and threaded sections simplifies the installation process while maintaining strong connection. The smooth first sections eliminate the complexity of aligning threads from the start, allowing the nut to be easily positioned. The threaded second sections then provide the secure connection through a simple rotational engagement. This segmentation transforms a complex single-step threading process into two simple sequential steps: slide onto smooth section, then rotate to engage threaded section, reducing overall complexity while maintaining connection strength.
