Electric Pump NFC Accessory Compartment Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric pumps face manufacturing difficulties due to multiple openings for power and accessory cables, leading to water infiltration and limited customization options, as users must predict accessory needs before purchase and cannot modify them post-production.
Innovation Solution
The electric pump features a compartment with a single opening for the power supply cable and uses NFC communication between an internal antenna and external devices on accessories, allowing for easy customization and installation of accessories without additional physical connections, reducing the risk of infiltration and simplifying manufacturing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple openings are provided for power supply cable and accessory cable, then electrical connections are established, but manufacturing complexity increases and water infiltration risk increases
Solution Approach 1:
The patent extracts the accessory cable connection function from the compartment opening requirements. By using NFC wireless communication, the accessory cable no longer needs to pass through the compartment, eliminating the need for additional openings and their associated sealing requirements.
Solution Approach 2:
The patent replaces the mechanical electrical connection system (physical cable passing through openings) with an electromagnetic field-based NFC communication system. This substitution eliminates the need for physical cable routing through sealed openings.
2Adaptability or versatility
If accessories are assembled during production, then electrical connections are secured, but user customization capability is reduced
Solution Approach 1:
The patent enables users to independently add accessories to the pump without requiring professional assembly services. The NFC-based system allows users to simply attach accessories with built-in NFC tags to the pump body, and the system automatically detects and configures them.
Solution Approach 2:
The patent transforms the static accessory configuration (fixed at production) into a dynamic, user-modifiable configuration. Users can add, remove, or change accessories at any time after purchase, making the system adaptable to changing needs.
3Device complexity
If multiple openings are provided in compartment, then cable passages are enabled, but number of sealing solutions required increases
Solution Approach 1:
The patent removes the need for accessory cable openings from the compartment design. By using wireless NFC communication, the accessory connection no longer requires penetration of the compartment wall, thereby eliminating additional sealing requirements.
