External Battery Unit for Engine System Space and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional engine systems with built-in automatic startup devices waste space and have bulky batteries, leading to inefficient use of space and complex maintenance procedures due to the detachable nature of the battery unit.
Innovation Solution
An external battery unit is attached to the engine system package, featuring a dedicated ventilation fan and a unit ventilating section to cool the battery externally, with a package ventilating section that introduces outside air to the bottom compartment, and a detachable inspection window for maintenance access without removing the battery unit or external wall panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automatic startup device with built-in battery is installed inside the package, then the engine can automatically start up in case of power failure, but large wasted space is left in the package and the battery is bulky
Solution Approach 1:
The automatic startup device is divided into two separate units: a control unit that remains inside the package and a battery unit that is mounted externally on the rear surface of the package. This segmentation allows the package to maintain automatic startup capability while eliminating wasted internal space and reducing the battery's bulky appearance.
Solution Approach 2:
The battery unit is relocated from the internal three-dimensional space of the package to an external mounting position on the rear surface. This dimensional transition from internal to external placement resolves the space utilization issue while preserving the automatic startup function through the control unit's continued presence inside the package.
2Volume of stationary object
If the battery unit is made compact, then space efficiency improves, but cooling effectiveness may be compromised
Solution Approach 1:
A dedicated cooling fan is introduced as an intermediary component between the battery unit and the external environment. This fan actively circulates air to provide effective cooling to the compact battery unit, ensuring that reduced size does not compromise thermal management.
3Ease of repair
If the battery unit is detachable for maintenance, then ease of maintenance improves, but the number of parts and assembly complexity increases
Solution Approach 1:
The battery unit is designed as a detachable module that can be easily removed from the rear surface of the package for maintenance. This segmentation provides ease of repair while the modular design minimizes the number of additional parts required compared to fully integrated designs.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration eliminates wasted space within the package, provides effective battery cooling, maintains ventilation path flexibility, and simplifies maintenance by allowing access to the drain water filter without removing the battery unit, thus enhancing operational efficiency and ease of maintenance.
Implementation Method 1
The battery unit includes a dedicated ventilation fan and a unit ventilating section that introduces outside air into an enclosure of the battery unit when the ventilation fan operates
Implementation Method 2
the package ventilating section introduces outside air through an outside air inlet provided in a bottom face of the enclosure and passes the outside air through an outside air outlet provided in a side face of the enclosure, to deliver the outside air to the bottom compartment through a vent provided in the external wall panel

AI summary
A radiator chamber is provided in a top compartment of a package, whereas an engine is provided in a bottom compartment. Outside the package, a battery unit is attached to an external wall panel (e.g., lower panel) of the bottom compartment. The battery unit includes a dedicated unit ventilation fan and a unit ventilating section that introduces outside air into an enclosure of the battery unit. The enclosure has a lower portion thereof divided to accommodate a package ventilating section that ventilates the bottom compartment of the package. There is provided a detachable bottom compartment inspection window in the external wall panel below the battery unit.
