Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If plug-in interfaces are used for charging and data transmission, then electrical connection can be established, but repeated insertion and extraction is required which is troublesome

Engineering Contradiction:

Improveconvenience of charging and data transmissionVSAvoidtime for repeated insertion and extraction

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces an interface conversion adapter as an intermediary device that converts the plug-in interface into a surface contact interface. This adapter remains permanently attached to the electronic device, serving as a mediator between the device and various charging/data transmission devices, thereby eliminating the need for repeated plug-in and unplugging operations.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical plug-in connection system with a surface contact system that uses magnetic attraction for positioning and spring needles for electrical connection. This substitution eliminates the need for deep insertion and extraction while maintaining reliable electrical contact through the spring-loaded needle mechanism.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Ease of operation

If inductive wireless charging technology is used, then charging can be performed without physical connection, but charging efficiency is low and device thickness increases

Engineering Contradiction:

Improveconvenience of wireless chargingVSAvoidcharging efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The interface conversion adapter acts as an intermediary that enables efficient wired charging while maintaining the convenience of wireless-like operation. By converting the plug-in interface to a surface contact interface, it allows for rapid charging through spring needle connections without the efficiency losses associated with inductive wireless charging.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Adaptability or versatility

If inductive wireless charging components are added, then wireless charging capability is achieved, but inner space of the electronic apparatus is occupied

Engineering Contradiction:

Improvewireless charging capabilityVSAvoidinner space of electronic apparatus

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

The patent segments the wireless charging functionality into an external adapter device rather than integrating it into the main electronic apparatus. The interface conversion adapter contains the necessary contact mechanisms and magnetic components separately, allowing the main device to maintain its compact form factor while gaining enhanced charging capabilities through the attached adapter.
