Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing faucet technologies face challenges in achieving a gapless fit between the handle and panel due to stringent flatness requirements, leading to increased friction, reduced service life, and complex assembly procedures with multiple components, which can result in assembly errors and user experience issues.
Innovation Solution
A handle assembly comprising a handle rod, a handle housing with a tapered through-hole, and elastic wear-resistant members to reduce friction and facilitate a gapless fit, along with an absorber to prevent waggle, using fewer components and allowing for easier assembly and adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a gapless fit is achieved between the handle and panel, then the appearance is improved, but the friction increases and service life decreases
Solution Approach 1:
The patent introduces a wear-resistant bushing as an intermediary component between the handle and panel. This bushing is received in the handle shell and supported by a snap ring, allowing the handle to achieve gapless fit with the panel while the bushing absorbs the friction and wear, thereby extending the service life of the handle assembly
Solution Approach 2:
The wear-resistant bushing is installed in advance in the handle shell to provide cushioning and protection against friction and wear before the handle is assembled to the panel. This beforehand cushioning prevents direct contact and friction between the handle and panel, reducing wear and extending service life while maintaining gapless fit appearance
2Shape
If a gapless fit is achieved between the handle and panel, then the appearance is improved, but the assembly requirements become more stringent
Solution Approach 1:
The wear-resistant bushing acts as a mediator that compensates for variations in panel flatness. By providing a standardized interface between the handle and panel, the bushing allows assembly without requiring stringent flatness tolerances, thereby achieving gapless fit appearance while reducing manufacturing precision requirements
3Shape
If multiple components are used to achieve gapless fit, then the fit quality is improved, but the assembly procedure becomes more complex
Solution Approach 1:
The patent combines multiple functions into the wear-resistant bushing component. The bushing simultaneously provides wear resistance, friction reduction, and positioning functions, eliminating the need for separate components and simplifying the assembly procedure while maintaining gapless fit quality
4Manufacturing precision
If the wear-resistant member is fine-processed, then the fit precision is improved, but the adjustability is reduced
Solution Approach 1:
The snap ring provides a dynamic and adjustable connection between the wear-resistant bushing and handle shell. This allows the assembly to be disassembled and reassembled with adjustments, providing adaptability while maintaining fine-processed fit precision through the precision-machined bushing and snap ring engagement
