Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and maintenance of batteries at cell sites are labor-intensive and time-consuming due to their weight and the high risk of theft, while there is a need for efficient recycling and monitoring of batteries to comply with environmental regulations.
Innovation Solution
A battery installation method using security screws and a reinforced bracket to secure batteries, combined with a mobile apparatus for efficient handling and recycling, including de-celling batteries into individual cells for easier handling and tracking through mobile devices and cloud systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If batteries are installed at cell sites for power backup, then network availability is improved, but labor intensity and installation time increase due to battery weight
Solution Approach 1:
The battery system is divided into individual battery units that can be handled separately. Each battery can be installed or removed independently, allowing for more efficient handling and reduced labor intensity compared to moving entire battery racks at once.
Solution Approach 2:
A battery handling apparatus serves as an intermediary tool between workers and heavy batteries. The apparatus includes features like forklift pockets and lifting mechanisms that facilitate easier transfer and installation of batteries, reducing the physical strain and time required for manual handling.
2Reliability
If batteries are installed at cell sites, then power backup is provided, but theft risk increases due to high battery value and accessibility
Solution Approach 1:
Security screws are installed on battery terminals and mounting brackets before batteries are placed in service. These security features create preliminary barriers that deter theft attempts, making it more difficult for thieves to quickly remove and transport batteries without specialized tools.
Solution Approach 2:
Security screws use asymmetric drive mechanisms (such as one-way ratchet mechanisms or proprietary head designs) that can be installed with standard tools but require specialized removal tools. This asymmetry creates a barrier to theft while maintaining ease of legitimate installation and maintenance.
3Quantity of substance
If multiple batteries are installed for adequate power backup, then energy capacity is improved, but handling difficulty increases due to severe weight
Solution Approach 1:
The total energy capacity is achieved through multiple separate battery units rather than one large unit. Each battery is designed to be a manageable size and weight, allowing workers to handle them individually with the assistance of the battery handling apparatus, rather than attempting to move a single extremely heavy unit.
Solution Approach 2:
The battery handling apparatus introduces vertical dimension capabilities through lifting mechanisms and adjustable height positions. This allows batteries to be elevated to comfortable working heights and positioned optimally during installation, reducing the physical strain of bending and reaching.
4Object-affected harmful factors
If security measures are added to prevent theft, then security is improved, but device complexity increases
Solution Approach 1:
Security features are applied locally to specific critical points (battery terminals and mounting brackets) rather than requiring comprehensive security systems throughout the entire cell site. This localized approach provides effective theft prevention while minimizing added complexity to the overall system.
Solution Approach 2:
Security screws are relatively simple, low-cost components compared to sophisticated electronic security systems. They provide adequate security for the intended application and can be replaced if needed without requiring complex diagnostic or replacement procedures.

AI summary
A battery installation method in a shelter or cabinet includes responsive to placing one or more batteries in the shelter or cabinet, connecting terminals on each of the one or more batteries to associated terminal plates with associated security screws; and connecting a bracket to a housing in the shelter or cabinet with associated security screws, wherein the bracket spans across the one or more batteries and wherein the bracket comprises raised edges which deter cutting.
