Solution Overview
Problem
Existing water purifying apparatuses with fixed main body connecting parts are prone to breakage or separation when force is applied during filter attachment or detachment, compromising the structural integrity and functionality.
Innovation Solution
A water purifying apparatus with rotatably mounted heads and a connecting cap that includes a rotation supporting part with a cap fixing part, restricting part, and guide hole, allowing for secure attachment and detachment of filters while maintaining the mounting state, and a connecting cap that shields the inlet and outlet parts to prevent separation.
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 be broken or separated when force is applied during filter attachment/detachment
Solution Approach 1:
The head is changed from a fixed structure to a rotatable structure, allowing it to rotate about a rotation axis. This dynamic capability enables the head to accommodate forces applied during filter attachment and detachment without breaking or separating, while maintaining overall structural simplicity through the rotation support mechanism.
2Ease of operation
If a rotatably mounted head is used to facilitate filter attachment/detachment, then the ease of operation is improved, but the mounting state may not be firmly maintained
Solution Approach 1:
The connecting cap is divided into multiple functional parts: a flow path part for water communication, a cover part for shielding, and a restricting part for fixation. This segmentation allows the cap to simultaneously enable head rotation for easy filter replacement while firmly maintaining the mounting state through the restricting part that prevents excessive rotation or detachment.
3Ease of operation
If the inlet part and outlet part are exposed, then the ease of operation for filter attachment is improved, but the parts may be separated or damaged
Solution Approach 1:
The cover part of the connecting cap acts as a protective shell that shields the inlet part and outlet part of the head. This protective covering prevents separation and damage to these exposed parts while allowing the head to rotate for filter attachment and detachment operations.

AI summary
A water purifying apparatus includes: a plurality of filters purifying and discharging introduced water along flow paths formed therein; a plurality of heads to which the plurality of filters are individually mounted to be detachable, the plurality of heads each having an inlet part and an outlet part, through which water is introduced and discharged; a mounting member to which the plurality of heads are mounted in parallel, the mounting member having a rotation supporting part that rotatably supports the head, and the rotation supporting part being formed recessed such that the inlet part and the outlet part are accommodated therein; and a connecting cap mounted on the rotation supporting part to connect the inlet part and the outlet part to communicate with each other.
