Solution Overview

Problem

The existing electric control box assemblies for electric appliances are complex and lack modularity, resulting in low assembly efficiency.

Innovation Solution

An electric control box assembly is designed with an outer box body, an insulating inner box body, and a component connected to the inner box body, facilitating modular assembly and improving assembly efficiency through integrated mounting brackets and fasteners.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If components are separately assembled in the outer box body, then flexibility in component placement is improved, but assembly complexity increases and assembly efficiency decreases

Engineering Contradiction:

Improvecomponent placement flexibilityVSAvoidassembly complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent combines the inner box body and component into an integrated modular assembly. The component is pre-mounted on the inner box body using mounting brackets and fasteners, creating a unified sub-assembly that reduces the number of separate assembly steps while maintaining placement flexibility through the modular design.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent divides the electric control box assembly into distinct modular components: outer box body, inner box body, mounting brackets, and fasteners. This segmentation allows the inner box body with its component to be assembled as a separate module first, then integrated into the outer box body, simplifying the overall assembly process.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If components are separately assembled in the outer box body, then installation flexibility is improved, but assembly time increases

Engineering Contradiction:

Improveinstallation flexibilityVSAvoidassembly time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent implements preliminary assembly of the component on the inner box body using mounting brackets and fasteners before integrating the assembly into the outer box body. This pre-assembly approach allows the component to be properly positioned and secured in advance, reducing the time required for final assembly while maintaining installation flexibility.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If modular design with mounting brackets is used, then assembly efficiency is improved, but structural complexity increases

Engineering Contradiction:

Improveassembly efficiencyVSAvoidstructural complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The mounting brackets are integrally formed with or closely coupled to the inner box body, merging the support structure with the box body itself. This integration reduces the number of separate structural elements while maintaining the modular assembly capability, thereby improving assembly efficiency without proportionally increasing structural complexity.

Inventive Principle:

Principle #5Merging (Combining)
