Electronic Mixing Tap Handle Stops for Stable Extended Motion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic taps with extended operative ranges lack independent regulation of passable and end-of-range stops, leading to instability and potential accidental activation of additional functions due to deformations under load, and fail to provide multiple functionalities across both rotational and tilting axes.
Innovation Solution
The electronic tap incorporates a cartridge with distinct passable and end-of-range stops, utilizing a cam mechanism with preloaded springs and triaxial magnetic sensors to detect handle positions, allowing independent regulation of extended ranges and preventing accidental activations by separating the elastic stop from the end-of-range stop, enabling multiple functionalities across both axes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single elastic piece is used to provide both the passable stop and end-of-range stop, then the device structure is simplified, but the stability and reliability deteriorate due to deformations under load causing accidental activation
Solution Approach 1:
The patent divides the single elastic piece into two separate components: a first elastic piece for the passable stop and a second elastic piece for the end-of-range stop. This segmentation allows each component to be independently optimized and regulated, preventing deformations in one from affecting the other, thus resolving the contradiction between structural simplicity and operational reliability.
2Adaptability or versatility
If the handle is allowed to move beyond the conventional end of range by overcoming resistance, then additional functionalities are enabled, but the risk of accidental activation increases due to lack of independent regulation
Solution Approach 1:
The patent applies different elastic properties and resistance characteristics to different segments of the handle's range of motion. The first elastic piece provides a softer, more compliant stop for the passable stop, while the second elastic piece provides a firmer, more resistant stop for the end-of-range stop. This local differentiation of mechanical properties enables extended functionality while preventing accidental activation through appropriately tuned resistance at each threshold.
3Adaptability or versatility
If continuous pressure is required to maintain the handle in the extended range position, then additional functions can be activated, but the ease of operation deteriorates due to user fatigue
Solution Approach 1:
The patent employs elastic pieces that store mechanical energy during compression, providing a cushioning effect that assists the user in returning the handle to its original position. The elastic recovery force reduces the effort required for operation, especially when transitioning between the conventional range and extended range, thereby maintaining ease of operation while enabling additional functions.

Implementation Method 1
a first passable stop formed by an element which at a first point in the path presents a certain resistance to continuing in said direction of displacement, and after applying a greater force than in the usual displacement of the cam, sufficient to overcome said resistance, continues moving said cam in said direction along a segment of increased path range
