Solution Overview

Problem

Conventional trays with handles tend to swing relative to the tray when carrying devices or modules, leading to damage and rust due to ineffective friction enhancement methods.

Innovation Solution

A casing assembly with a pivotable component and handle, where the handle is rotatable about a pivotable component displaced from the fixing end of a positioning slot on the carrier, and an engagement element on the handle is removably located in the positioning slot, preventing the handle from rotating and thus the carrier from swinging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If bumps are added to increase friction between handle and tray, then the swinging of the tray relative to the handle is reduced, but the bumps easily wear and scratch the surface of the tray and the handle resulting in damage and rust

Engineering Contradiction:

Improvestability of carrier relative to handleVSAvoidsurface integrity of tray and handle

Core Design Contradiction:

Stability of the object's compositionVSReliability

Solution Approach 1:

The patent extracts the friction enhancement function from physical bumps and replaces it with a mechanical engagement mechanism. The engagement element (protrusion) on the handle interacts with the positioning slot on the carrier to prevent swinging, eliminating the need for surface bumps that cause wear and damage.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces an intermediary engagement mechanism between the handle and carrier. The engagement element positioned in the positioning slot acts as a mediator that transmits the connection force, preventing carrier swinging without requiring direct friction contact between the handle surface and carrier surface.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If the handle is made movable for easy storage and opening, then the ease of operation is improved, but the carrier tends to swing relative to the handle when being held

Engineering Contradiction:

Improveease of handle storage and openingVSAvoidstability of carrier relative to handle

Core Design Contradiction:

Ease of operationVSStability of the object's composition

Solution Approach 1:

The patent applies dynamics by making the handle pivotably connected to the carrier through a pivotable component. This allows the handle to be movable for easy storage and opening while the engagement element provides stability when needed. The system transitions between dynamic (movable) and static (engaged) states as required.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent segments the handle-carrier connection into two functional parts: the pivotable component that enables movement and storage, and the engagement element that provides stability during handling. This segmentation allows each part to fulfill its specific function without interfering with the other.

Inventive Principle:

Principle #1Segmentation
