Shower Filter Case With Adjustable Filling Material Outflow
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional shower filter cases cannot adjust the quantity of outflowing filling material arbitrarily and suffer from excessive discharge when not in use, leading to a shortened product lifespan and marketability issues due to oxidation of vitamin C.
Innovation Solution
A shower filter case with an outflow quantity-adjusting mechanism featuring a rotating part and fixing part with communicating holes, allowing users to control the discharge through a screw-coupled system and a ball member to prevent excessive discharge when the shower stops, ensuring complete closure and extended product life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a discharge hole is formed at one end of the filter case, then the filling material can be discharged to mix with shower water, but the quantity of outflow cannot be adjusted arbitrarily by the user
Solution Approach 1:
The discharge hole is made adjustable through a rotating cap that can be positioned at different angles, transforming a static discharge structure into a dynamic one. This allows the user to control the outflow quantity by rotating the cap to different positions, resolving the contradiction between ease of operation and device complexity.
Solution Approach 2:
The discharge quantity is controlled by changing the effective opening area of the discharge hole through rotational movement of the cap. By adjusting the parameter of opening area, the system achieves variable outflow control without requiring a completely complex discharge mechanism.
2Ease of manufacture
If the filter case is made of plastic material, then it is easy to manufacture, but the filling material is excessively discharged when the shower stops, shortening the use term
Solution Approach 1:
A ball member is placed in advance within the discharge hole to prevent excessive discharge of filling material when the shower stops. This preliminary protective measure counteracts the harmful effect of backflow or pressure differential that would otherwise cause material loss, thereby extending the use term while maintaining the simple plastic construction.
Solution Approach 2:
The ball member acts as an intermediary element between the filling material and the discharge hole. It prevents direct excessive discharge by blocking the hole when water flow stops, while still allowing controlled discharge during operation, thus extending the filling material's lifespan without complicating the plastic filter case design.
3Reliability
If the discharge hole is closed by adhesive tape, then it provides temporary sealing, but it is not completely sealed and difficult to be kept for long periods
Solution Approach 1:
The adhesive tape is used as a temporary, disposable sealing solution for initial transport protection. The design accepts that this short-term sealing is insufficient for long-term storage, hence the need for additional protective packaging like vacuum packing for extended keeping periods beyond immediate use.

Function Achieved in This Case
Enables users to adjust the filling material output arbitrarily, preventing excessive discharge during non-use and maintaining product freshness, thus extending its usage and marketability.
Implementation Method 1
the filling material is excessively discharged by the pressure formed by the contraction of the filter case
Implementation Method 2
a rotating part having a discharge hole formed at the inside thereof in such a manner as to be passed through the upper and lower surfaces thereof, the rotating part being screw-coupled to the inner periphery of the fixing part
Implementation Method 3
the filling material is melted together with the water (for example, tap water) flowing along the shower
Implementation Method 4
the vitamin C, as a component of the filling material, is naturally oxidized by the contact with air and water and is changed to dark red color
