Solution Overview

Problem

Existing emergency cases lack improved visibility, ease of use, and stability during transport and deployment, particularly in low-light conditions, and often require complex production methods.

Innovation Solution

The emergency case features a handle design with symmetrical, vertically extending portions, a central third portion along the inner edge for balance, and optional fluorescent or phosphorescent materials for enhanced visibility, along with a method involving hot stamping to apply phosphorescent layers for improved visibility and cost-effective production.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If fluorescent or phosphorescent materials are applied to the emergency case, then visibility in low-light conditions is improved, but production complexity and cost increase

Engineering Contradiction:

ImprovevisibilityVSAvoidproduction complexity

Core Design Contradiction:

Illumination intensityVSDevice complexity

Solution Approach 1:

The patent applies fluorescent and phosphorescent materials to the emergency case to enhance its visibility in low-light conditions. These materials change the optical properties of the case, causing it to glow or reflect light, thereby improving illumination intensity without requiring additional active lighting components.

Inventive Principle:

Principle #32Color changes

Solution Approach 2:

The patent uses composite materials by combining fluorescent or phosphorescent substances with the case material. This allows the case to have both structural integrity and enhanced visibility properties, integrating multiple functions into a single component rather than adding separate visibility enhancement devices.

Inventive Principle:

Principle #40Composite materials

2Ease of operation

If a handle with specific geometric configuration is used, then ease of transport and deployment is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Improveease of transportVSAvoidhandle geometry precision

Core Design Contradiction:

Ease of operationVSManufacturing precision

Solution Approach 1:

The handle is designed with segmented geometric portions, including a first portion extending from an outer corner, a second portion extending toward the inner longitudinal edge, and a third portion along the inner edge. This segmentation allows each portion to be optimized for specific functional requirements while simplifying the overall manufacturing process by breaking down the complex handle geometry into manageable sections.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The handle features asymmetric geometric configuration where the first, second, and third portions extend in different directions and at different angles. This asymmetric design provides optimal ergonomics and handling characteristics while the specific angular relationships between portions are designed to be manufacturable using standard molding techniques.

Inventive Principle:

Principle #4Asymmetry

3Loss of time

If the emergency case is designed for rapid deployment, then response time is reduced, but structural stability may be compromised

Engineering Contradiction:

Improvedeployment timeVSAvoidstructural stability

Core Design Contradiction:

Loss of timeVSStability of the object's composition

Solution Approach 1:

The emergency case is designed with pre-assembled components and pre-configured structures that allow for rapid deployment. The handle, body, and internal components are prepared in advance during manufacturing, enabling quick assembly and deployment in emergency situations without requiring complex assembly procedures.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The emergency case incorporates dynamic design elements that allow it to transition from a stable stored configuration to a rapidly deployable configuration. The handle and body structure are designed to maintain structural integrity during normal use while allowing for quick opening, removal, or deployment actions when needed.

Inventive Principle:

Principle #15Dynamics

AI summary

An emergency case (100, 200) comprises at least one case shell (10), wherein a handle (12) is formed in the case shell (10). Shoulder ends of the handle are located on the upper outer corners (14a, 14b) of the case shell (10). First portions (16a, 16b) of the handle extend vertically upward, and second portions (18a, 18b) extend towards the inner longitudinal edge of the case shell. A third portion connects the two second portions (18a, 18b) along the inner longitudinal edge (22).
