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

VSEngineering 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

Engineering Contradiction:
Improvemanufacturing complexityVSAvoidwater infiltration risk
Core Design Contradiction:
Ease of manufactureVSReliability

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.

Inventive Principle:
Principle #2Taking out (Extraction)

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.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If accessories are assembled during production, then electrical connections are secured, but user customization capability is reduced

Engineering Contradiction:
Improveuser customization capabilityVSAvoidassembly process complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #25Self-service

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.

Inventive Principle:
Principle #15Dynamics

3Device complexity

If multiple openings are provided in compartment, then cable passages are enabled, but number of sealing solutions required increases

Engineering Contradiction:
Improvesealing solutions quantityVSAvoidcompartment sealing precision
Core Design Contradiction:
Device complexityVSManufacturing precision

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.

Inventive Principle:
Principle #2Taking out (Extraction)
