Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The uncertainty of LED light bulb interface types in lighting systems leads to increased costs and risks for servicers due to unknown inventory requirements, as they must carry double inventory or perform pre-service inspections, which are time-consuming and costly.

Innovation Solution

A converter device that transforms a bi-pin interface to a wedge interface in LED lighting systems, allowing servicers to carry only bi-pin type LED lights and use the converter to interface with either type, reducing inventory needs and service time.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If servicers carry double inventory (both wedge and pin interface bulbs), then they can service any interface type without pre-inspection, but inventory costs and storage requirements increase

Engineering Contradiction:

Improveservice readinessVSAvoidinventory quantity

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The wedge converter enables a single bi-pin LED bulb to interface with both wedge and pin sockets through the converter adapter, making the bulb universally compatible with multiple interface types without requiring separate inventory for each interface type

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The wedge converter acts as an intermediary device between the bi-pin LED bulb and the wedge socket, allowing electrical connection and mechanical compatibility without requiring the bulb itself to be designed for wedge interfaces

Inventive Principle:

Principle #24Intermediary (Mediator)

2Quantity of substance

If servicers perform pre-service inspections to determine bulb requirements, then inventory accuracy improves, but service time and trip costs increase

Engineering Contradiction:

Improveinventory accuracyVSAvoidservice time

Core Design Contradiction:

Quantity of substanceVSLoss of time

Solution Approach 1:

The converter allows servicers to bring all necessary components (bi-pin bulbs and converters) to the site in advance without needing to perform preliminary inspections to determine the specific interface type required, eliminating the time-consuming inspection step

Inventive Principle:

Principle #10Preliminary action

3Area of stationary object

If servicers rely on shipped inventory, then storage space requirements decrease, but shipping costs and time lags increase

Engineering Contradiction:

Improvestorage spaceVSAvoidinventory availability time

Core Design Contradiction:

Area of stationary objectVSLoss of time

Solution Approach 1:

By making the bulb type universal through the converter, servicers can maintain a single type of inventory (bi-pin bulbs) that can be shipped once and used for all interface types, reducing both storage space needs and shipping frequency while maintaining quick availability

Inventive Principle:

Principle #6Universality (Multi-functionality)
