Heavy Vehicle Battery Pack Cover for Vertical Stacking Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packs in vehicles, particularly heavy vehicles like trucks, face issues of space constraints due to their positioning under the chassis, leading to reduced space for other components and increased manufacturing costs due to varying battery dimensions across countries.
Innovation Solution
A modular battery pack design with a base and cover that allows vertical stacking of batteries, featuring a releasable connection and locking mechanism for easy access and secure fixation, enabling versatile and compact storage of batteries of varying dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If battery packs are positioned underneath the vehicle chassis, then batteries are protected from the external environment, but space for other components (reservoirs) is reduced
Solution Approach 1:
The patent transitions from horizontal placement of batteries to vertical stacking arrangement. By utilizing the vertical dimension beneath the chassis, the design accommodates multiple battery units stacked one above another, thereby maximizing space utilization while maintaining protection and avoiding conflict with horizontally positioned reservoirs.
Solution Approach 2:
The battery pack design implements a nested structure where multiple battery units are stacked vertically within a common protective housing. Each battery is contained within the same structural envelope, allowing compact arrangement that protects all batteries while minimizing the overall footprint under the chassis.
2Area of stationary object
If a very compact battery pack is provided for housing electrical batteries one above the other, then space utilization is improved, but adaptability to different battery dimensions is reduced
Solution Approach 1:
The battery pack structure is divided into modular components including individual battery housings, a common protective structure, and adjustable mounting elements. This segmentation allows the same basic design to accommodate different battery sizes by reconfiguring or replacing individual modules without redesigning the entire pack.
Solution Approach 2:
The common protective housing and mounting structure are designed with universal features that can accommodate multiple battery types and dimensions. Adjustable brackets, flexible positioning mechanisms, and standardized connection points enable the same battery pack design to suit batteries from different manufacturers and countries.
3Ease of manufacture
If batteries are housed one above the other in a compact arrangement, then manufacturing costs are reduced, but ease of access for maintenance is worsened
Solution Approach 1:
The battery pack incorporates movable or adjustable components such as removable panels, adjustable brackets, and flexible mounting mechanisms. These dynamic features allow easy access to individual batteries for maintenance while maintaining the compact vertical stacking arrangement during normal operation.
Solution Approach 2:
The design allows individual batteries or battery modules to be extracted from the stack for maintenance or replacement. Removable sections of the protective housing and detachable mounting mechanisms enable technicians to access specific batteries without disassembling the entire pack structure.
