Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional string light assemblies are designed with multiple separate components (sockets, lampshades, wires, light elements), then the assembly process becomes complex and time-consuming, but the structural integrity and reliability are improved

Engineering Contradiction:
Improveease of assemblyVSAvoidnumber of parts
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines multiple separate components (socket, lampshade, wire connections, and light element housing) into a single integrated light component assembly. This merging reduces the total number of parts that need to be handled during assembly and simplifies the overall structure while maintaining functional integrity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the string light system into modular light components that can be independently assembled and replaced. Each light component is a self-contained module with standardized interfaces, allowing for easy assembly and interchangeability without affecting the entire string light system.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If conventional string light assemblies use fixed, non-interchangeable components, then the manufacturing process is simplified, but the ability to customize and adapt the appearance is reduced

Engineering Contradiction:
Improvecustomization capabilityVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent designs the light component with universal interfaces and standardized connection points that accommodate different types of lampshades and light elements. This universality allows a single base component to support multiple customization options without requiring different manufacturing processes for each variant.

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

Solution Approach 2:

The patent introduces dynamic interchangeability to the light component design, where lampshades and light elements can be easily swapped during use. This dynamic capability allows the product to adapt to different user preferences and applications while the core manufacturing process remains standardized and efficient.

Inventive Principle:
Principle #15Dynamics

3Reliability

If conventional string light assemblies use traditional bulb sockets, then compatibility with various light elements is improved, but the reliability and energy efficiency are reduced

Engineering Contradiction:
Improveoperational reliabilityVSAvoidlight element compatibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent transitions from traditional incandescent bulb sockets to LED-compatible electrical connections, changing the electrical parameters (lower voltage, different current requirements) to improve reliability and energy efficiency. The socket design is adapted to accommodate LED modules while maintaining secure electrical and mechanical connections.

Inventive Principle:
Principle #35Parameter changes

AI summary

A string light assembly having a plurality of light components is described. Each light component comprises a first cover, a second cover, and a collar for coupling the first and second covers together. When coupled, the first and second covers form a housing that has an interior space. The interior space is sized and dimensioned to house an electrical socket and a pair of electrical wires. The electrical socket electrically and removably couple with a light element such as an LED bulb. The light component also includes a lampshade that either removably couples with the collar or is integrally formed with the light element.
