Solution Overview

Problem

Conventional vehicle control apparatuses face issues with increased weight and volume due to heat dissipation fins, which restrict shape and may cause damage from increased weight, while high-performance CPUs generate excessive heat reducing reliability and durability.

Innovation Solution

A vehicle control apparatus utilizing a base bracket that replaces conventional heat dissipation fins, incorporating a heat sink and multiple brackets to effectively transfer heat and reduce stress concentration, allowing for improved heat dissipation and reduced weight.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If conventional heat dissipation fins are used, then heat dissipation performance is improved, but volume and weight increase

Engineering Contradiction:

Improveheat dissipation performanceVSAvoidweight of control apparatus

Core Design Contradiction:

TemperatureVSWeight of stationary object

Solution Approach 1:

The patent combines the heat dissipation function with the mounting bracket structure. The base bracket serves dual purposes: mechanically mounting the control apparatus to the vehicle body and simultaneously acting as a heat dissipation fin. This integration eliminates the need for separate heat dissipation components, reducing overall weight while maintaining effective heat transfer from the housing to the vehicle body through the bracket.

Inventive Principle:

Principle #5Merging (Combining)

2Temperature

If conventional heat dissipation fins are used, then heat dissipation performance is improved, but volume increases and shape is restricted

Engineering Contradiction:

Improveheat dissipation performanceVSAvoidvolume of control apparatus

Core Design Contradiction:

TemperatureVSVolume of moving object

Solution Approach 1:

The mounting bracket is designed to perform multiple functions: structural support for mounting the control apparatus, stress distribution across the housing, and heat dissipation. By making the bracket multi-functional, the patent eliminates the need for additional dedicated heat dissipation fins, thereby reducing the overall volume and avoiding shape restrictions that would result from adding separate heat dissipation components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Power

If high-performance CPU is used, then processing power is improved, but heat generation increases

Engineering Contradiction:

Improveprocessing powerVSAvoidheat generation

Core Design Contradiction:

PowerVSTemperature

Solution Approach 1:

The base bracket acts as an intermediary heat transfer path between the control apparatus housing (which contains the high-performance CPU) and the vehicle body. Heat from the CPU is conducted through the housing to the base bracket, which then transfers the heat to the vehicle body. This intermediary structure provides an efficient heat dissipation pathway that enables the use of high-performance CPUs without excessive temperature rise.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Device complexity

If single bracket is used, then mounting is simplified, but stress concentration occurs

Engineering Contradiction:

Improvemounting structure complexityVSAvoidstress concentration

Core Design Contradiction:

Device complexityVSStress or pressure

Solution Approach 1:

The mounting structure is segmented into multiple brackets (base bracket and side brackets) that are distributed across different locations on the housing. This segmentation distributes the mechanical stress from mounting and vibration across multiple contact points rather than concentrating it at a single location, thereby reducing stress concentration while maintaining relatively simple mounting procedures.

Inventive Principle:

Principle #1Segmentation
