Dual-Compartment Storage Case for Isolated Power Source Carrying

Solution Overview

Problem

Existing storage cases for power-driven personal care implements do not adequately store the power source with the implement, leading to inconvenience, potential loss, and risk of short-circuit due to contamination.

Innovation Solution

A storage case with separate compartments for the power-driven personal care implement and power source, where the power source is electrically unconnected and isolated from electrical conductors, preventing contamination and ensuring safe storage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the power source is stored separately from the storage case, then the risk of short-circuit is reduced, but the convenience of carrying and the risk of loss increase

Engineering Contradiction:

Improveshort-circuit preventionVSAvoidconvenience of carrying

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The storage case is divided into two separate compartments: a first compartment for storing the power-driven personal care implement and a second compartment for storing the power source. This segmentation allows the power source to be stored together with the implement for convenience while maintaining electrical isolation to prevent short-circuits, thus resolving the contradiction between reliability and ease of operation.

Inventive Principle:

Principle #1Segmentation

2Ease of operation

If the power source is stored together with the power-driven personal care implement in one compartment, then the convenience of carrying is improved, but the risk of short-circuit due to contamination increases

Engineering Contradiction:

Improveconvenience of carryingVSAvoidshort-circuit prevention

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The storage case is divided into two separate compartments: a first compartment for storing the power-driven personal care implement and a second compartment for storing the power source. This segmentation allows the power source to be stored together with the implement for convenience while maintaining electrical isolation to prevent short-circuits, thus resolving the contradiction between reliability and ease of operation.

3Device complexity

If a single compartment storage case is used, then the device complexity is reduced, but the ability to store both implement and power source safely together is compromised

AI summary

A storage case for storing a power-driven personal care implement includes a primary cavity and a primary cover, preferably movably connected to the primary cavity. The primary cavity and the primary cover define a primary compartment configured to store the power-driven personal care implement therein. The primary cover is configured to set the primary compartment in an open position or a closed position. The storage case includes a secondary cavity and a secondary cover, preferably movably connected to the secondary cavity. The secondary cavity and the secondary cover define a secondary compartment separate from the primary compartment. The secondary cover is configured to set the secondary compartment in an open position or a closed position. The secondary compartment is configured to store a power source electrically unconnected to any electrical conductors.
