Solution Overview

Problem

Traditional decorative lighting systems face issues with long light strings that are prone to tangling and knotting during assembly and storage, leading to increased assembly difficulty and reduced usability due to cumbersome storage requirements.

Innovation Solution

A connecting assembly for decorative lights comprising a connecting piece, light string, and sleeve, with modular connectors and anti-slip patterns, allowing for easy assembly, disassembly, and storage, while preventing tangling and knotting.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If a single light string is used to continuously thread all positions of decorative patterns, then the decorative light can be assembled, but the light string becomes excessively long, making it prone to tangling and knotting during assembly and storage

Engineering Contradiction:
Improveassembly processVSAvoidstorage convenience
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

The light string is divided into multiple segments, each connected to a separate connecting piece. Instead of using one continuous long light string, the patent segments the light string into shorter sections (e.g., first light string, second light string) that can be independently managed and stored, eliminating tangling and knotting issues while maintaining the complete decorative effect when assembled.

Inventive Principle:
Principle #1Segmentation

2Reliability

If a single light string is used to continuously thread all positions, then the decorative pattern can be completed, but the overall reserved length of light strings increases, making the laying process difficult and time-consuming

Engineering Contradiction:
Improvedecorative pattern completenessVSAvoidassembly time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The decorative light system is segmented into multiple independent units, each with its own connecting piece and light string segments. This allows parallel assembly of multiple units and reduces the time required for threading and laying compared to managing one extremely long continuous light string.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The connecting pieces are pre-assembled with light string segments and connectors before the final assembly. This preliminary preparation of modular units speeds up the overall assembly process, as the complex threading operation is broken down into simpler connection steps between pre-prepared modules.

Inventive Principle:
Principle #10Preliminary action

3Area of stationary object

If the light string is made long to cover all decorative positions, then the complete decorative effect is achieved, but the storage volume increases and requires cumbersome winding or folding

Engineering Contradiction:
Improvecoverage areaVSAvoidstorage volume
Core Design Contradiction:
Area of stationary objectVSVolume of stationary object

Solution Approach 1:

The light string is segmented into multiple shorter sections, each attached to a separate connecting piece. These segmented units can be stored in a compact, organized manner without requiring extensive winding or folding, significantly reducing the storage volume compared to a single long light string while maintaining the ability to cover the same decorative area when assembled.

Inventive Principle:
Principle #1Segmentation

4Ease of operation

If connectors are added to enable modular assembly, then disassembly and assembly become easier, but the device complexity increases

Engineering Contradiction:
Improvedisassembly and assembly convenienceVSAvoidconnector structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

Connecting pieces serve as intermediary components between light string segments and decorative elements. These connectors provide standardized interfaces (male/female connectors, snap-fit mechanisms) that simplify the assembly and disassembly process, making the system more operationally convenient despite adding modular components.

Inventive Principle:
Principle #24Intermediary (Mediator)
