Inclined Battery Case Layout for Rolling Compaction Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing rolling compaction vehicles face difficulties in efficiently compacting road surfaces due to the heavy and large-scale attachable and detachable batteries, which are cumbersome to replace and require significant operator effort, disrupting continuous operation when the battery's state of charge is low.
Innovation Solution
The vehicle is equipped with a battery case positioned higher than the rolling compaction wheels, allowing the battery's weight to contribute to the compaction load, and is inclined to reduce the distance and effort needed for battery replacement, with an insertion hole design that facilitates easier attachment and detachment of batteries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If an attachable and detachable battery with large discharge capacity is used, then the operation duration of the rolling compaction vehicle is extended, but the battery becomes heavy and large in scale, making attachment and detachment difficult and increasing operator burden
Solution Approach 1:
The battery case is positioned in an inclined posture such that the opening is at a lower position than the opposite end, creating a gravity-assisted configuration where the battery naturally slides into place during attachment and can be easily removed by tilting the vehicle body, reducing operator effort despite the battery's large size and weight
2Force
If the battery case is positioned at a higher position than the rolling compaction wheels, then the battery weight contributes to compaction load, but the opening for battery attachment becomes harder to reach
Solution Approach 1:
The battery case is designed with asymmetric positioning where the opening is located at a lower position than the opposite end, creating an inclined configuration that simultaneously achieves adequate compaction load through high placement while making the opening accessible to operators from the rear of the vehicle
3Device complexity
If a built-in battery incapable of being replaced is used, then the vehicle structure is simpler, but the vehicle cannot operate when the battery charge capacity is low
Solution Approach 1:
The battery system is segmented into a replaceable battery unit and a battery case, allowing the battery to be detached and replaced when charge capacity is low, thereby maintaining operational continuity while keeping the overall vehicle structure relatively simple through modular design
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 enables efficient road surface compaction by distributing the battery weight effectively and simplifies battery replacement, ensuring continuous operation with reduced operator burden and improved vehicle design.
Implementation Method 1
the battery case is placed in an inclined posture in which the opening faces an outer edge of the vehicle body and the wall portion faces an interior of the vehicle body, and a lower end of the wall portion is at a lower position than a lower end of the opening
Implementation Method 2
the battery case is provided in the vehicle body at a higher position than the frontward rolling compaction wheel and the rearward rolling compaction wheel... enabling efficient road surface compaction by distributing the battery weight effectively

AI summary
A vehicle body of a rolling compaction vehicle is provided with a battery case and a motor. A removable battery is removably housed in an insertion hole of the battery case. The battery case is in an inclined position. This inclination causes an opening of the insertion hole to face an outer edge of the vehicle body, and causes a wall portion that holds back the removable battery to face the inside of the vehicle body. Here, the lower end of the wall portion is located at a position lower than the lower end of the opening. Electric power of the removable battery is supplied to the motor.
