Concentric Shower Hose Structure for Adjustable Outlet Temperature
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current hose structures for water outlet devices like showerheads lack the ability to adjust the flow rate of cold and hot water, preventing temperature adjustment of the outlet water.
Innovation Solution
A hose structure with a temperature adjusting mechanism that includes a water outlet joint assembly with a temperature adjusting head and knob, allowing for control of the hot water flow rate by rotating the temperature adjusting head, which changes the water passing area without affecting the cold water flow rate, thus adjusting the outlet water temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single-channel hose structure is used, then the device complexity is reduced, but the ability to adjust outlet water temperature is lost
Solution Approach 1:
The hose structure is divided into separate cold water and hot water channels within a single hose body. The temperature adjusting mechanism segments the hot water flow control into multiple adjustable openings, allowing independent control of hot water flow rate while maintaining a simple integrated hose structure.
Solution Approach 2:
The temperature adjusting mechanism incorporates a rotatable temperature adjusting head with multiple hot water openings that can be dynamically adjusted by rotating the head. This dynamic adjustment capability allows the user to change the effective flow area of hot water openings, thereby controlling the hot water flow rate and outlet temperature without increasing overall structural complexity.
2Temperature
If a temperature adjusting mechanism is added to control hot water flow rate, then the outlet water temperature becomes adjustable, but the device complexity increases
Solution Approach 1:
The temperature adjusting mechanism is merged with the water outlet joint assembly, integrating the temperature control function into the existing connection structure. The temperature adjusting head combines multiple hot water openings in a single component that rotates to adjust flow, rather than using separate valves for each opening, thereby reducing the number of parts and simplifying the overall assembly.
Solution Approach 2:
The temperature adjusting head serves multiple functions simultaneously: it acts as a flow control valve, a temperature mixing regulator, and a connection element within the water outlet joint assembly. By making this single component multi-functional, the patent avoids adding separate mechanisms for each function, thereby limiting the increase in device complexity while achieving temperature adjustment capability.

AI summary
A hose structure for a shower with adjustable water outlet temperature, which includes a hose body (1) and a water outlet joint assembly (2) arranged at one end of the hose body and configured for being connected to a water outlet device. The hose body (1) is provided with concentric through cold (18) and hot (19) water channels. The annular hot water channel (19) surrounds the cold water channel (18) or the annular cold water channel (18) surrounds the hot water channel (19). A temperature adjusting mechanism is provided in the water outlet joint assembly (2) and configured for adjusting the flow rate of hot water flowing out of the hose body (1).
