Solution Overview

Problem

There is a need for a solution to provide safe, convenient access to electrical outlets within storage units, such as pull-out drawers, to minimize clutter and manage wiring effectively, especially in areas like bathrooms where devices are frequently used and recharged, without exposing cords and wires on countertops.

Innovation Solution

An electrical outlet mounting apparatus with rotatably connected, collapsible arms that house and manage electrical cords, featuring a mounting plate with a strain relief groove to secure the cord and provide accessible electrical connections within the drawer, allowing for the concealment of cords and reduced clutter.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electrical outlets are provided inside pullout storage units or drawers, then access to electrical outlets is concealed and clutter is minimized, but wiring management and cord safety become more complex

Engineering Contradiction:
Improveaccess to electrical outletsVSAvoidwiring management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent employs flexible arms with integrated channels that can bend and flex to accommodate drawer movement while protecting the electrical cord. The arms act as flexible conduits that guide the cord from the wall outlet through the moving drawer structure, eliminating the need for rigid wiring and simplifying installation while maintaining safety.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The mounting apparatus with arms and channels serves as an intermediary mechanism between the fixed wall outlet and the moving drawer. This intermediate structure manages the cord transition, allowing the cord to flex and move with the drawer while remaining protected and organized, thus resolving the wiring management complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If multiple devices are stored and charged inside a drawer, then countertop clutter is reduced, but cord management and strain relief become more challenging

Engineering Contradiction:
Improvedevice storage and chargingVSAvoidcord management
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The flexible arms with embedded channels provide a protected pathway for the electrical cord as it moves with the drawer. This flexible structure accommodates the movement and positioning of multiple devices within the drawer while keeping the cord organized and protected from damage, simplifying cord management for multiple devices.

Inventive Principle:
Principle #30Flexible shells and thin films

Solution Approach 2:

The patent integrates the cord management system within the drawer structure itself, with channels nested within the arms and the cord nested within the channels. This nested arrangement keeps all cords organized within the drawer's internal structure, preventing clutter while accommodating multiple devices.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If electrical cords are concealed within drawer structures, then aesthetic appearance and clutter reduction are improved, but cord accessibility and strain relief installation become more difficult

Engineering Contradiction:
Improveaesthetic appearance and clutter reductionVSAvoidstrain relief installation
Core Design Contradiction:
Ease of operationVSEase of manufacture

Solution Approach 1:

The strain relief feature is pre-integrated into the mounting plate during manufacturing, with the groove for cord reception and strain relief already formed as part of the mounting plate structure. This preliminary integration simplifies installation, as the strain relief functionality is built-in rather than requiring separate installation steps, thus maintaining ease of manufacture while achieving cord concealment.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent combines multiple functions into the mounting plate: electrical connection, strain relief, and cord guidance. The groove for strain relief is merged with the mounting plate structure, and the arms with channels are integrated to provide both structural support and cord management. This merging reduces the number of separate components and simplifies installation while maintaining aesthetic appearance.

Inventive Principle:
Principle #5Merging (Combining)
