Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing water purifying apparatuses with fixed main body connecting parts are prone to breaking or separation when forces are applied for filter attachment or detachment, compromising the stability and durability of the mounting system.
Innovation Solution
A water purifying apparatus with rotatably mounted heads and a mounting member that includes a rotation supporting part with a connecting cap, which has a flow path part, a restricting part for elastic deformation, and a cover part to securely fix and communicate the inlet and outlet parts, ensuring stable mounting and easy filter replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a fixed main body connecting part is used to connect filter mounting parts, then the structure is simple, but the connecting part may break or separate when force is applied for filter attachment or detachment
Solution Approach 1:
The patent applies the dynamics principle by making the connecting cap rotatable rather than fixed. The connecting cap can rotate along with the head assembly during filter attachment and detachment operations, allowing dynamic movement that absorbs applied forces and prevents breaking or separation of the connection parts.
2Ease of operation
If a rotatably mounted head is used for easy filter replacement, then the ease of operation is improved, but the mounting system may become less stable
Solution Approach 1:
The head assembly is designed to rotate freely for easy filter replacement, while the connecting cap rotates synchronously to maintain stable connection throughout the operation. This dynamic coordination ensures both ease of operation and mounting stability.
Solution Approach 2:
The connecting cap acts as an intermediary between the rotatable head assembly and the fixed mounting structure. It mediates the rotational motion, allowing the head to rotate for filter replacement while maintaining a stable connection to the mounting member through its own rotational capability.
3Ease of repair
If the connecting cap is made detachable for easy maintenance, then the ease of repair is improved, but the risk of separation during operation increases
Solution Approach 1:
The connecting cap is designed with detachable features for easy maintenance, but during normal operation it rotates synchronously with the head assembly, maintaining reliable connection. The detachable nature is activated only when the head assembly is removed from the mounting member, preventing accidental separation during operation.
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 solution provides a stable and durable mounting system that prevents the separation of the connecting cap from the rotation supporting part, allowing for easy filter replacement and continuous water supply without leakage, enhancing the operational stability and efficiency of the water purifying apparatus.
Implementation Method 1
a restricting part extending from the flow path part to be elastically deformed, the restricting part being fixed to the cap fixing part
