Water Purifier Filter Head Rotation Mounting to Prevent Cap Separation
Find Innovative SolutionsGenerate Solutions
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 stability and durability of the mounting system.
Innovation Solution
A rotatably mounted head system with a guide hole, intersecting ribs, and a connecting cap that includes a stopper and elastic parts to securely fix and rotate the head, ensuring stable mounting and easy filter replacement without compromising water flow.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed main body connecting part is used to connect filter mounting parts, then the structure is simple and easy to manufacture, but the connecting part may be broken or separated when force is applied during filter attachment or detachment
Solution Approach 1:
The patent applies the dynamics principle by making the head rotatable on the mounting member. This dynamic feature allows the head to rotate during filter attachment and detachment, distributing applied forces away from the connecting cap and preventing breakage or separation, while maintaining a relatively simple overall structure.
2Reliability
If a rotatably mounted head system is used to prevent breakage, then the reliability is improved, but the device complexity increases due to additional components like guide holes, ribs, and stoppers
Solution Approach 1:
The mounting member serves multiple functions: it provides structural support, enables rotation of the head, guides the connecting cap during assembly, and prevents over-rotation. By integrating these multiple functions into a single component, the patent avoids the need for separate guide mechanisms, reducing overall device complexity while maintaining high reliability.
Solution Approach 2:
The connecting cap acts as an intermediary element that connects the head to the mounting member while accommodating rotational movement. It includes a guide part that interacts with the guide hole and a stopper that prevents over-rotation, thereby mediating between the rotational movement and the fixed mounting structure without requiring complex additional components.
3Ease of operation
If multiple components are added to enable rotation and prevent separation, then the reliability and ease of operation are improved, but the device complexity increases
Solution Approach 1:
The connecting cap acts as an intermediary element that connects the head to the mounting member while accommodating rotational movement. It includes a guide part that interacts with the guide hole and a stopper that prevents over-rotation, thereby mediating between the rotational movement and the fixed mounting structure without requiring complex additional components.
4Reliability
If the head is fixed firmly to prevent separation, then the reliability is improved, but the ease of operation for filter replacement decreases
Solution Approach 1:
The patent applies the dynamics principle by making the head rotatable on the mounting member. This dynamic feature allows the head to rotate during filter attachment and detachment, distributing applied forces away from the connecting cap and preventing breakage or separation, while maintaining a relatively simple overall structure.
