Solution Overview

Problem

The existing housing structures with frames arranged to cross the vertical direction but not in contact with each other in the vertical direction face rigidity issues when a load is applied vertically, such as during lifting.

Innovation Solution

A housing structure comprising a first frame, a second frame positioned below the first frame with a handle part and an action surface extending in a direction crossing the vertical direction, and an accommodation part with an overlapping part that overlaps the action surface, securing rigidity without additional frames.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If two frames are arranged to cross the vertical direction without contact, then the housing structure achieves simplicity and ease of assembly, but the rigidity becomes insufficient when vertical loads are applied

Engineering Contradiction:

Improvehousing structureVSAvoidrigidity

Core Design Contradiction:

Device complexityVSStrength

Solution Approach 1:

The accommodation part extends in the vertical direction to create an overlapping region between the first and second frames. This vertical dimension addition allows the accommodation part to bridge the gap between frames, providing load transmission path in the vertical direction while maintaining the non-contact arrangement of frames.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The accommodation part acts as an intermediary element between the first frame and second frame. It receives external forces applied to the handle part of the second frame and transmits them to the first frame through its overlapping structure, enabling indirect load transfer without direct frame contact.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Strength

If additional frames are added to improve rigidity, then the structural strength increases, but the device complexity and assembly difficulty increase

Engineering Contradiction:

ImproverigidityVSAvoidhousing structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The accommodation part serves multiple functions simultaneously: it accommodates the substrate, provides structural support, transmits loads between frames, and enhances rigidity. This multi-functionality eliminates the need for separate reinforcement frames, maintaining simplicity while improving strength.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The accommodation part is merged with the substrate housing structure, integrating the load-bearing function into the existing accommodation structure. This merging approach avoids adding separate frames by combining the substrate housing with the load transmission function.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A housing structure includes: a first frame; a second frame positioned below the first frame and provided with a handle part, the second frame having an action surface that extends in a direction crossing the vertical direction and on which the external force applied to the handle part acts; and an accommodation part accommodating a substrate positioned between the first frame and the second frame, the accommodation part including an overlapping part overlapping the action surface of the second frame in an up-down direction.
