Solution Overview
Problem
Current household water filtration systems are complex and difficult for users to maintain, leading to time-consuming and laborious filter core replacement operations, which can result in water pollution and reduced appliance functionality.
Innovation Solution
A filter device with a rotatable cabin door and gear driving assembly that simplifies the replacement of the filter core by allowing easy insertion and extraction, utilizing a gear-mounting slot, driving rack, and torsion spring mechanism to facilitate quick and efficient filter core changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water filtration system is added into household electrical appliances, then drinking water quality is improved, but the structure becomes complex and filter core replacement becomes difficult
Solution Approach 1:
The filter device is segmented into a filter core and a filter cabin, allowing the filter core to be independently replaced without dismantling the entire filtration system. The filter core can be directly inserted into or extracted from the filter cabin through the cabin door, simplifying maintenance operations while maintaining reliable water filtration.
2Adaptability or versatility
If the filter core replacement operation is complex, then the filtration system can be comprehensive, but users are confused and operation becomes time-consuming
Solution Approach 1:
The gear driving assembly and driving rack are pre-configured on the filter core, and the gear-mounting slot is pre-positioned on the cabin door. When the filter core is inserted, these components automatically engage to secure the filter core in place, eliminating the need for users to perform complex manual assembly operations and reducing replacement time.
3Reliability
If the filter core is securely fixed in the cabin body, then filtration reliability is ensured, but extraction and replacement becomes difficult
Solution Approach 1:
The fixing mechanism transitions from a static complex assembly to a dynamic automatic engagement system. The gear driving assembly and driving rack automatically engage when the filter core is inserted, providing secure fixation. When replacement is needed, the filter core can be easily extracted by reversing the insertion motion, allowing the mechanism to dynamically switch between secure fixation and easy removal states.
