Solution Overview

Problem

Existing socket systems with extension cords lack flexibility and efficiency in power distribution, as they often require multiple separate cords and connectors, which can be cumbersome and inefficient in managing power flow.

Innovation Solution

A socket system with extension cord that includes a main connecting block and multiple side connecting blocks, allowing for efficient power distribution through a single main cord and multiple output cords, with optional additional connecting blocks for increased flexibility.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple separate cords and connectors are used for power distribution, then power can be supplied to multiple devices, but the system becomes cumbersome and inefficient in managing power flow

Engineering Contradiction:
Improvepower distribution capabilityVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent combines multiple separate cords and connectors into a single integrated extension cord assembly. The main cord connects to the wall outlet, and multiple branch cords with connectors are integrated into this single structure, allowing power distribution to multiple devices while reducing the number of separate components the user must manage.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The extension cord assembly serves multiple functions: the main cord provides power connection to the wall outlet, while multiple branch cords with connectors enable simultaneous power distribution to multiple devices. This multi-functional design eliminates the need for separate cords for each device.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Productivity

If a single main cord with multiple output cords is used, then power distribution efficiency is improved, but additional connecting blocks are needed for increased flexibility

Engineering Contradiction:
Improvepower distribution efficiencyVSAvoidnumber of connecting blocks
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The extension cord is divided into modular segments: a main cord with a wall outlet connector, and multiple branch cords with device connectors. This segmentation allows the system to be configured flexibly by connecting or disconnecting individual branch cords as needed, providing adaptability without requiring a completely different system for each configuration.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If multiple separate connectors are used, then each device can be connected independently, but managing power flow becomes cumbersome

Engineering Contradiction:
Improvedevice connection flexibilityVSAvoidpower flow management
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The patent merges multiple independent connector management tasks into a single integrated extension cord unit. Users manage one main cord and one extension cord assembly rather than multiple separate cords, significantly simplifying power flow management while maintaining the ability to connect multiple devices independently through the integrated branch connectors.

Inventive Principle:
Principle #5Merging (Combining)
