Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing on-board power source devices with stacked battery modules require multiple discharge pipes and complex connections to efficiently discharge gas, increasing the number of parts and reducing space utilization efficiency.
Innovation Solution
The on-board power source device incorporates a frame member with a hollow discharge space and a bracket that communicates the outlets of stacked power storage modules directly with this space, eliminating the need for separate discharge pipes and allowing gas from multiple modules to be merged and discharged externally.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate discharge pipes are connected to each battery module outlet, then gas discharge reliability is improved, but the number of parts increases and space utilization efficiency deteriorates
Solution Approach 1:
The patent merges multiple discharge pipes into a single common discharge pipe that collects gas from multiple battery modules. The discharge pipes are merged in sequence, where the discharge pipe of one module serves as a continuation of the previous module's discharge path, eliminating the need for separate external discharge pipes for each module while maintaining reliable gas discharge from all modules.
2Reliability
If separate discharge pipes are provided for each battery module, then gas discharge effectiveness is improved, but space utilization efficiency deteriorates
Solution Approach 1:
The discharge pipes are merged in sequence within the limited space, utilizing the vertical arrangement of battery modules. The discharge pipe of the upper module continues downward to connect with the lower module's discharge path, effectively using the available vertical space and eliminating the need for separate horizontal discharge pipe routes for each module.
Solution Approach 2:
The patent transitions from horizontal discharge pipe arrangement to vertical discharge pipe arrangement, utilizing the vertical dimension created by stacking battery modules. This dimensional change allows the discharge pipes to be integrated along the vertical axis rather than requiring separate horizontal space for each module's discharge pipe.
3Reliability
If multiple discharge pipes are arranged to guarantee discharge space, then gas discharge capability is improved, but the overall device weight increases
Solution Approach 1:
Multiple discharge pipes are merged into a single common discharge pipe structure, reducing the total amount of pipe material required. The sequential merging design allows the discharge pipes to share common pathways, thereby reducing the overall weight compared to providing completely separate discharge pipes for each battery module.
