Removable Handle Jig for Energy Storage System Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing energy storage system (ESS) battery packs are difficult to handle due to their weight, and the inclusion of a handle for mounting purposes makes the pack less economical and space-inefficient after installation.
Innovation Solution
A jig set comprising a mounting unit with a fastening portion, latch portion, and head portion, and a handle unit with a locking bar that can be attached and detached from the mounting unit, allowing for easy handling and transportation of the ESS pack without the need for a permanent handle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a handle is added to the ESS pack for mounting convenience, then ease of operation is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The handle function is segmented from the ESS pack body. The mounting unit with protruding portion is integrated into the pack, while the handle unit with locking bar is separate and attachable only during mounting operations. This segmentation allows the handle to be removed after use, eliminating permanent structural complexity.
Solution Approach 2:
The handle configuration is made dynamic rather than static. The locking bar can be attached to the protruding portion during mounting and then removed afterward. This dynamic attachment/detachment mechanism allows the system to adapt between having handle functionality during installation and being handle-free during normal operation.
2Ease of operation
If a handle is integrated into the ESS pack structure, then ease of operation is improved, but manufacturing cost increases
Solution Approach 1:
By segmenting the handle into a separate attachable unit rather than integrating it permanently into the pack structure, the manufacturing process is simplified. The ESS pack can be manufactured without handle components, reducing material costs and assembly complexity, while still providing handle functionality when needed through the separate mounting unit.
Solution Approach 2:
The handle unit is designed to be discarded after the mounting operation is complete. The locking bar is removed from the protruding portion after the ESS pack is installed on the wall, eliminating the need for permanent handle components and reducing manufacturing costs while maintaining operational functionality.
3Ease of operation
If a handle is permanently attached to the ESS pack, then ease of operation is improved, but space efficiency deteriorates
Solution Approach 1:
The handle configuration transitions from a permanent fixed structure to a temporary dynamic attachment. The locking bar is attached to the protruding portion only during the mounting process and then removed, allowing the ESS pack to maintain its full space efficiency during normal operation while still providing handle functionality when needed.

AI summary
A jig set for mounting an ESS pack, which is used to mount an ESS pack to a wall or a structure corresponding to the wall, includes: a mounting unit having a partially protruding portion capable of being coupled to one surface of an ESS pack case; and a handle unit including a handlebar to be grasped by an operator, and a locking bar, which is integrally connected to the handlebar and is attachable to and detachable from the protruding portion of the mounting unit.
