Solution Overview

Problem

Existing power adapter solutions for battery-powered electrical devices often lack efficient storage and handling mechanisms, leading to clutter and inconvenience when not in use.

Innovation Solution

The proposed adapter assembly includes a power box with a housing containing internal components, a storage portion for convenient storage of the adapter, and a cord wrap arrangement for managing cords, along with a foot design that elevates the power box for improved airflow and protection from contaminants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the power adapter is stored loosely without a dedicated storage structure, then it occupies minimal space during use, but it creates clutter and is inconvenient when not in use

Engineering Contradiction:
Improvestorage convenienceVSAvoidstorage structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The power box housing serves multiple functions: it houses the power adapter components, provides a storage portion for the adapter when not in use, and includes cord wrap arrangements for managing power cords. This multi-functionality resolves the contradiction by integrating storage and organization features into the existing power box structure without adding separate complex storage systems.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Object-affected harmful factors

If the power box is placed directly on the support surface, then it has stable support, but it allows contaminants to enter and reduces airflow

Engineering Contradiction:
Improvecontaminant protectionVSAvoidsupport stability
Core Design Contradiction:
Object-affected harmful factorsVSStability of the object's composition

Solution Approach 1:

The housing is segmented to include feet that project from the bottom surface, creating a physical separation between the power box and the support surface. This segmentation allows the housing to maintain stability through the feet while simultaneously preventing direct contact that would allow contaminant entry and blocking airflow.

Inventive Principle:
Principle #1Segmentation

3Ease of operation

If cords are left loose without management, then they are easily accessible, but they create clutter and are difficult to manage

Engineering Contradiction:
Improvecord managementVSAvoidcord wrap arrangement
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The cord wrap arrangement merges the cord management function into the power box housing structure. The housing includes integrated cord wraps that combine storage and organization capabilities, allowing cords to be neatly wound and secured within the housing rather than left loose externally.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An adapter assembly including a power box that has a housing containing internal components, a longitudinal axis and a storage portion. The adapter assembly also includes a first cord coupled to and extending from the housing, an adapter including an engagement portion that is removably coupled to the storage portion of the housing and that selectively engages a power source-receiving portion of a tool, and a second cord having a first end coupled to the adapter and a second end coupled to the housing.
