Sliding Battery Support Assembly for Easy Blackout Blind Maintenance
Find Innovative SolutionsGenerate Solutions
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
Engineering 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
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.
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.
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
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.
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.
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
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.
