Solution Overview

Problem

Existing blackout devices with photovoltaic power supply units require cumbersome dismantling of the front panel for battery maintenance, leading to musculoskeletal disorders and lengthy replacement times, and are not easily removable or cost-effective.

Innovation Solution

A power supply assembly with support pieces that allow easy access to the battery without disassembling the front panel, featuring a sliding connection and snap-fit mechanism for tool-free installation and removal, using lightweight thermoplastic materials for low-cost manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the photovoltaic panel and battery are mounted on the front panel, then the battery is easily accessible for replacement, but the front panel becomes heavy and bulky requiring complete dismantling

Engineering Contradiction:
Improvebattery accessibilityVSAvoidfront panel weight
Core Design Contradiction:
Ease of operationVSWeight of stationary object

Solution Approach 1:

The power supply assembly is segmented into separate support pieces (first and second support pieces) that can be independently attached to the front panel. Each support piece holds a portion of the battery assembly, allowing the battery to be accessed by removing only the support pieces rather than the entire front panel, thus reducing the weight and complexity of dismantling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The battery and photovoltaic panel are extracted from the main housing and mounted on separate support pieces that attach to the front panel. This extraction allows the battery to be independently accessible - the support pieces can be removed without dismantling the entire front panel, solving both accessibility and weight issues.

Inventive Principle:
Principle #2Taking out (Extraction)

2Stability of the object's composition

If the power supply unit is securely mounted to the front panel, then the installation is stable, but battery maintenance requires complete dismantling of the front panel

Engineering Contradiction:
Improvepower supply unit stabilityVSAvoidbattery maintenance ease
Core Design Contradiction:
Stability of the object's compositionVSEase of repair

Solution Approach 1:

The power supply assembly is divided into modular support pieces that can be independently attached and detached. The first and second support pieces can be removed separately to access the battery, maintaining stable installation during operation while enabling easy maintenance without complete front panel dismantling.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The support pieces are designed with dynamic attachment characteristics - they provide stable mounting during normal operation but can be quickly detached for maintenance. The support pieces include attachment mechanisms that ensure stability when mounted but allow rapid removal when needed for battery replacement.

Inventive Principle:
Principle #15Dynamics

3Strength

If traditional mounting methods are used for the power supply unit, then the installation is secure, but the production cost increases and assembly time lengthens

Engineering Contradiction:
Improvemounting strengthVSAvoidproduction cost
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

Traditional mechanical mounting methods (screws, bolts, complex fastening systems) are replaced with a simplified support piece design that uses elastic deformation and friction-based attachment. The support pieces attach to the front panel through elastic deformation of their structure, providing secure mounting without requiring additional fasteners or complex mechanical systems, thereby reducing production costs and assembly time.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
