Solution Overview

Problem

Existing electronic ballasts and converters face challenges in heat dissipation due to the need for precise housing dimensions that match the specific configuration of electronic components, leading to potential overheating and damage, as well as the requirement for custom housings for different device types.

Innovation Solution

A housing design comprising two adjustable housing parts that telescope together, allowing for varying heights and interior dimensions, ensuring heat-producing components are close to housing walls for effective heat transfer, and can be adapted for different electronic configurations without the need for individual housing designs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the housing is designed with fixed dimensions for optimal heat dissipation, then heat transfer efficiency is improved, but adaptability to different electronic components deteriorates

Engineering Contradiction:
Improveheat dissipation efficiencyVSAvoidadaptability to different electronics
Core Design Contradiction:
TemperatureVSAdaptability or versatility

Solution Approach 1:

The housing is divided into a base housing part and an adjustable housing part that can be connected in different configurations. This segmentation allows the housing dimensions to be adjusted while maintaining good thermal contact between electronic components and housing walls for effective heat dissipation.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The housing dimensions are made dynamically adjustable through different connection configurations of the housing parts. This enables the housing to adapt to various electronic component arrangements while ensuring optimal heat transfer pathways are maintained.

Inventive Principle:
Principle #15Dynamics

2Temperature

If custom housing designs are created for each type of device, then optimal heat transfer is achieved, but device complexity and manufacturing cost increase

Engineering Contradiction:
Improveheat transfer effectivenessVSAvoidhousing design variety
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

A single base housing part design can be combined with adjustable housing parts in multiple configurations to serve different electronic component arrangements. This universal base design reduces the need for completely custom housing designs for each device type while maintaining effective heat transfer.

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

Solution Approach 2:

The adjustable housing part is designed to nest onto the base housing part, allowing different configurations to be achieved through stacking or telescoping arrangements. This nesting approach enables dimension adjustment without requiring entirely different housing designs.

Inventive Principle:
Principle #7Nested doll (Nesting)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design enables efficient heat dissipation across a range of electronic configurations, ensuring reliable operation within prescribed temperature ranges and allowing a single housing to accommodate various device types, thereby simplifying the design and use of electronic ballasts and converters.

Implementation Method 1

The heat can be dissipated relatively well to the environment via the metal housing walls. The prerequisite for this, however, is that the heat generated by the electronic components is first effectively transferred to the housing walls.

Methodology Applied
Scientific EffectThermal conduction: Conduction (thermal)
