Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional faucets have limited motion types due to mechanical coupling, restricting the versatility of handle movements for controlling water parameters like temperature and flow rate.
Innovation Solution
A faucet assembly with a handle that rotates about an angled interface, allowing movement between multiple configurations to control water parameters, featuring a selector attachment base with a longitudinal axis and a handle attachment base with a rotational axis offset from the handle axis, enabling angular adjustments for temperature and flow control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional mechanical coupling is used in faucet handles, then the structure is simple and easy to manufacture, but the types of motion available for handle movement are limited
Solution Approach 1:
The faucet handle system is divided into separate functional components: a handle body, a carrier with bearing, and a valve stem. This segmentation allows independent optimization of each component's motion capabilities while maintaining overall system simplicity.
Solution Approach 2:
The patent introduces angular/tilt motion in addition to the traditional rotational motion by allowing the handle body to pivot relative to the carrier on a different axis than the valve stem rotation. This adds a new dimension of motion control for adjusting water parameters.
2Measurement precision
If traditional handle designs are used, then manufacturing is straightforward, but precision control of water temperature and flow rate is limited
Solution Approach 1:
The handle system transitions from fixed mechanical linkages to a dynamic configuration where the handle body can independently tilt and rotate relative to the carrier. This dynamic capability enables more precise control of water parameters through varied motion types.
Solution Approach 2:
The carrier with bearing acts as an intermediary component between the handle body and valve stem, enabling complex motion transmission while maintaining ease of assembly through standardized bearing interfaces.
3Measurement precision
If the handle rotational axis is offset from the handle longitudinal axis, then angular positioning control is improved, but the mechanical coupling becomes more complex
Solution Approach 1:
The offset rotational interface is segmented into the handle body, carrier, and valve stem components, with the bearing providing the offset rotation capability. This segmentation simplifies the overall design by distributing complexity across separate, manageable components.
Solution Approach 2:
The system utilizes angular parameters (tilt angle, rotation angle) as control variables, with the offset rotational axis enabling independent adjustment of these parameters for precise water parameter control.
