Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the battery height is increased to improve endurance mileage, then the energy density is improved, but the height above ground is reduced making the battery vulnerable to damage
Solution Approach 1:
The patent transitions from a conventional flat battery layout to a three-dimensional structure with a recess at the top of the housing. This allows the longitudinal beam to pass through the battery housing, enabling battery cells to be arranged on multiple levels and at the sides, effectively utilizing vertical and lateral space dimensions to increase energy density without compromising ground clearance.
Solution Approach 2:
The longitudinal beam is nested within the battery housing structure, passing through the recess. This allows the beam to be integrated into the battery assembly, with battery cells arranged around and along the beam, creating a compact nested configuration that maximizes space utilization.
2Productivity
If the battery is placed at the bottom of the vehicle to maximize space utilization, then the space efficiency is improved, but the battery swapping operation becomes complex and costly
Solution Approach 1:
The battery housing is segmented with a recess that allows the longitudinal beam to pass through, creating distinct mounting regions. This segmentation enables the battery to be detached and replaced more easily, as the beam passage provides natural separation points for mounting and unmounting operations.
Solution Approach 2:
The recess structure serves multiple functions: it allows the longitudinal beam to pass through for structural support, provides mounting surfaces for the battery cells, and creates accessible interfaces for battery swapping operations. This multi-functionality simplifies the swapping process while maintaining space efficiency.
3Quantity of substance
If the battery cells are arranged at the bottom layer to maximize energy density, then the energy density is improved, but the height above ground is reduced increasing the risk of damage
Solution Approach 1:
The patent utilizes vertical and lateral dimensions by creating a recess structure that allows battery cells to be arranged at different heights and positions. This three-dimensional arrangement increases the height above ground of critical components while maintaining high energy density through efficient space utilization in all directions.

AI summary
Provided are a battery and a vehicle. The battery includes a battery cell and a housing. The battery cell is accommodated in the housing. The housing includes a first housing portion and two second housing portions located at two sides of the first housing portion in a first direction. The battery cell is disposed in each of the first housing portion and the two second housing portions. A recess is defined by the first housing portion and the two second housing portions together. The recess is a through recess in the first direction and opened towards a second direction. The battery is adapted to be disposed at a bottom of a vehicle. A vehicle-bottom longitudinal beam of the vehicle is adapted to pass through the recess in the first direction and to be detachably mounted in the recess in the second direction. The first direction intersects the second direction.
