Helicoidal Knob Capsule Diffuser for Shower Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for diffusing encapsulated products into water streams, such as shower or bath water, require complex handling and space for opening and closing, and often lead to leaks or unnecessary product exposure.
Innovation Solution
A compact diffusion device with a helicoidally rotating knob that securely seals a peripherally flanged capsule, allowing easy insertion and closure without the need for additional space, featuring a water supply and return system that automates product release and mixing with water.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a traditional housing with hatch or stopper is used, then the capsule can be inserted and sealed, but the device requires additional space for opening and closing operations and increases device complexity
Solution Approach 1:
The knob combines multiple functions: it serves as the sealing element, the closure mechanism, and the operation interface. By merging these functions into a single component that rotates to between 0° (open) and 90° (closed) positions, the device eliminates the need for separate hatches or stoppers, reducing overall device volume while maintaining ease of operation through a simple rotational motion
Solution Approach 2:
The sealing mechanism transitions from static (fixed hatches or stoppers) to dynamic through the rotational knob that moves between open and closed positions. This dynamic element allows the housing to transition between accessible and sealed states without requiring additional space for manual opening/closing operations, as the rotation itself performs the sealing action
2Ease of operation
If a hatch or stopper mechanism is used, then the device can be opened and closed, but it increases the number of handling operations required by the user
Solution Approach 1:
The knob integrates the closure and sealing functions into a single operational element. Users perform only one rotational operation to both close the housing and seal the capsule, eliminating the need for separate opening and closing steps that would be required by traditional hatch or stopper mechanisms
Solution Approach 2:
The rotational knob automatically performs the sealing action as part of its closure movement. The sealing surface on the knob works self-contained within the rotation mechanism, requiring no additional sealing operations or complex multi-step procedures to secure the capsule
3Reliability
If the housing is kept open for capsule insertion, then the capsule can be inserted simply and quickly, but the product may be exposed to water or air before sealing
Solution Approach 1:
The housing is designed with an open state during insertion, allowing quick capsule placement. The sealing action is prepared in advance through the rotational mechanism, which can immediately seal the capsule upon rotation to the closed position, preventing product exposure without requiring additional sealing steps after insertion
Solution Approach 2:
The housing transitions dynamically from an open state (0°) during insertion to a sealed state (90°) after capsule placement. This dynamic transition allows the user to benefit from both quick insertion and immediate sealing protection, as the same rotational mechanism that enables access also provides secure sealing without intermediate exposure risks
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device ensures efficient and space-saving diffusion of encapsulated products into water streams with minimal user handling, preventing leaks and ensuring product integrity by automated puncturing and sealing mechanisms.
Implementation Method 1
the knob and the bearing surface being mounted with the capacity for helicoidal rotation one with respect to the other
Implementation Method 2
capable of bringing a lower face of the rim and the bearing surface closer together in order by compression to hold a peripheral portion of the flange of the capsule between the rim and the bearing surface in a sealed manner
Implementation Method 3
Device for diffusing an encapsulated material in a water stream
Implementation Method 4
a pump or a suction system is used to expel the product contained in the capsule and mix it into a stream of water passing through the device
