Removable Cargo Case with Slide Rail Unit for Electric Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric cargo vehicles require significant labor and time to load or unload heavy or large quantities of cargo due to the need to open and close a swivel door, increasing labor costs and transport time.
Innovation Solution
A cargo vehicle with a removable cargo case featuring a slide rail unit and a connecting mechanism that allows the cargo case to be easily loaded and unloaded by moving it along rail sets, reducing the effort required for access and handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a swivel door is used to access the cargo accommodation space, then the cargo vehicle can transport significant quantity of cargo, but significant labor is required to load or offload the cargo and increase transport time
Solution Approach 1:
The cargo hold unit is segmented into a removable cargo case and the vehicle body. The cargo case can be completely detached from the vehicle, allowing users to easily carry away loaded cargo and attach empty cases, significantly reducing the labor required compared to opening and closing a swivel door for each loading/unloading operation
Solution Approach 2:
The connection between the cargo case and vehicle body is made dynamic through removable connecting members. The cargo case can be quickly attached and detached at designated positions, transforming the static cargo hold into a dynamic system that adapts to different cargo handling needs, thereby improving operational efficiency
2Quantity of substance
If a swivel door is used to access the cargo accommodation space, then the cargo vehicle can transport significant quantity of cargo, but transport time is increased due to repeated door operations
Solution Approach 1:
By segmenting the cargo hold into removable cargo cases, the system eliminates the need for repeated door operations. Users can attach entire loaded cargo cases directly to the vehicle, reducing the time-consuming process of individually loading and unloading cargo through a swivel door
Solution Approach 2:
The cargo cases are pre-assembled and can be prepared in advance at designated positions. This preliminary preparation allows for quicker loading operations as the cargo cases are ready to be attached to the vehicle, reducing overall transport time
3Ease of operation
If the cargo case is made removable with slide rail mechanism, then labor required for loading/unloading is reduced, but device complexity is increased
Solution Approach 1:
The slide rail mechanism acts as an intermediary between the cargo case and vehicle body. This intermediate structure provides a guided path for the cargo case to slide into and out of the vehicle, reducing the complexity of direct manual handling while maintaining ease of operation
Solution Approach 2:
The slide rail mechanism is designed to guide the cargo case automatically during the loading and unloading process. The structure itself facilitates the movement and positioning of the cargo case without requiring additional complex mechanical systems or significant human effort

AI summary
A cargo vehicle includes a vehicle unit (1), a cargo case (2), a slide rail unit (3), and a connecting unit (4). The vehicle unit (1) includes a vehicle frame (11) including a frontal frame body (111), and two rear frame bodies (112) cooperatively define an accommodation space (113) with the frontal frame body (111). The cargo case (2) is removably disposed in the accommodation space (113). The slide rail unit (3) includes two first rail sets (31) mounted on the cargo case (2), and two second rail sets (32) mounted on the rear frame bodes (112). The first rail sets (31) are removably coupled to the second rail sets (32) so that the cargo case (2) is moveable relative to the vehicle frame (11). The connecting unit (4) includes a first connecting set (5), and a second connecting set (6) removably coupled to the first connecting set (5).
