Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional taps with extended operative ranges lack the ability to provide additional functionalities beyond conventional motion ranges, as they rely on a single elastic stop for both rotational and tilting motions, limiting the range of motion and functionality.
Innovation Solution
A cartridge with separate passable and end-of-range stops for both rotational and tilting motions, utilizing cam mechanisms and triaxial magnetic sensors to detect handle positions, allowing extended ranges of motion and enabling multiple additional functions by discriminating between different motion ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single elastic stop is used for both rotational and tilting motions, then the device complexity is reduced, but the extent of automation and measurement precision are limited
Solution Approach 1:
The patent divides the stop mechanism into separate components: a first stop for rotational motion and a second stop for tilting motion. This segmentation allows each stop to be independently optimized for its specific function, improving position detection precision while maintaining manageable device complexity through modular design.
Solution Approach 2:
The patent introduces a cam mechanism as an intermediary between the handle and the stop mechanisms. The cam translates handle movements into distinct rotational and tilting motions that can be independently controlled by separate stops, enabling precise position detection without requiring a complex integrated stop system.
2Adaptability or versatility
If the handle is allowed to move beyond conventional range by overcoming resistance, then the operative range is extended, but the force required increases
Solution Approach 1:
The patent implements dynamic stop mechanisms where the first stop allows passage in the rotational direction with controlled resistance, and the second stop allows passage in the tilting direction. This dynamic design enables the handle to extend beyond conventional ranges when needed while maintaining normal operation within standard ranges, optimizing the balance between operative range and required force.
Solution Approach 2:
The patent applies different stop characteristics to different directions of motion: the first stop is optimized for rotational motion with specific resistance properties, while the second stop is optimized for tilting motion. This local quality differentiation allows extended operative range in both directions without requiring excessive force in either case.
3Adaptability or versatility
If continuous pressure is applied to maintain extended range position, then additional functions are activated, but the ease of operation decreases
Solution Approach 1:
The patent employs spring-loaded stop mechanisms that automatically return the handle to its conventional position when the user releases pressure. This self-service feature allows temporary activation of additional functions through brief handle movements without requiring continuous user effort to maintain the extended position, significantly improving ease of operation while preserving functional versatility.
Solution Approach 2:
The patent enables periodic or transient activation of additional functions through brief handle movements into extended ranges, rather than requiring sustained pressure. The spring mechanisms facilitate this periodic action by automatically returning the handle to the conventional position, allowing users to activate functions momentarily without continuous effort.
