Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The challenge of securely and efficiently interconnecting large energy storage modules in vehicles, particularly heavy-duty vehicles, to achieve a sufficient energy capacity for long-range operation without excessive weight and complexity.
Innovation Solution
A method involving two sets of energy storage modules connected by rods with sleeves and protection plates, where rods are threaded through holes and sleeves, allowing for secure, modular, and efficient assembly without long clamping lengths, and guided by pins for precise alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If a single long rod is used to connect energy storage modules, then the connection spans the entire arrangement, but the clamping length becomes too long which increases the risk of loosening bolts over time
Solution Approach 1:
The patent divides a single long rod connection into multiple shorter rod segments. Each rod connects adjacent energy storage modules or groups of modules, creating intermediate connection points. This segmentation reduces the clamping length of each individual rod while maintaining overall structural integrity and reducing bolt loosening risk.
2Quantity of substance
If energy storage modules are connected to achieve large energy capacity, then the vehicle range is extended, but the assembly complexity and difficulty increase
Solution Approach 1:
The energy storage system is divided into modular units that can be independently assembled and then connected using standardized rod mechanisms. This modular approach allows the system to scale in energy capacity while maintaining consistent assembly procedures, reducing overall complexity.
Solution Approach 2:
The rods are pre-positioned through predetermined holes in the energy storage modules before final tightening. This preliminary positioning ensures proper alignment and reduces the skill level required for assembly, making it easier to assemble larger energy storage arrangements.
3Strength
If energy storage modules are securely connected, then the structural integrity is improved, but the assembly process becomes more difficult
Solution Approach 1:
The rods are inserted through predetermined holes in the energy storage modules before final tightening. This preliminary positioning ensures proper alignment and reduces the skill level required for assembly, making it easier to assemble securely connected modules.
Solution Approach 2:
The rod acts as an intermediary element that simplifies the connection process. By using a standardized rod mechanism with predetermined holes, the patent provides a simple assembly procedure while still achieving secure connections between modules.
4Length of stationary object
If long rods are used to connect energy storage modules, then the connection spans the entire arrangement, but the risk of loosening bolts over time increases
Solution Approach 1:
The patent divides a single long rod connection into multiple shorter rod segments. Each rod connects adjacent energy storage modules or groups of modules, creating intermediate connection points. This segmentation reduces the clamping length of each individual rod while maintaining overall structural integrity and reducing bolt loosening risk.
