Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a battery case is designed to accommodate a battery module, then the battery module can be mounted, but the battery case becomes large in volume and weight, reducing interior space
Solution Approach 1:
The battery case is merged with the cooling device into an integrated structure. The battery case serves dual functions as both the housing for the battery module and as the cooling device housing, eliminating the need for a separate cooling device housing and reducing overall volume
Solution Approach 2:
The battery case is designed to perform multiple functions: it houses the battery module, serves as the cooling device housing, and provides the cooling function through integrated cooling channels. This multi-functionality reduces the number of separate components and optimizes space utilization
2Temperature
If a cooling device is added to cool the battery module, then cooling performance is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The cooling device is merged with the battery case into a single integrated structure. The cooling channels are formed directly within the battery case, eliminating the need for separate cooling pipes and reducing structural complexity
Solution Approach 2:
The battery case itself serves as the cooling device through integrated cooling channels. The case structure provides its own cooling function without requiring external cooling systems, simplifying the overall device architecture
3Temperature
If the cooling device is driven, then cooling function is activated, but driving sound flows into the interior through the inflow hole, causing passenger discomfort
Solution Approach 1:
A noise reduction member is introduced as an intermediary element between the cooling device and the interior space. This member blocks the transmission of driving sound from the cooling device into the vehicle interior while allowing the cooling function to operate
Solution Approach 2:
The noise reduction member is specifically positioned at the inflow hole where noise enters the interior. The member provides localized noise blocking at the critical interface between the cooling device and the passenger compartment
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
The solution effectively secures interior space, enhances cooling efficiency, and reduces passenger discomfort by minimizing noise from the cooling device and electrical components, while maintaining cost-effectiveness.
Implementation Method 1
a cooling device connected to the air discharge port to circulate the interior air to the internal space
Implementation Method 2
a first noise reduction member disposed between the cooling device and the inflow hole to block the driving sound generated when the cooling device is driven from flowing into the interior through the inflow hole
