Commercial Vehicle Cab Door Secures Lateral Storage Box
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing driver's cab side wall storage boxes for commercial vehicles require a separate lock and Bowden cable for secure operation, increasing costs and complexity.
Innovation Solution
The driver's cab door is used to block and secure the storage box outer wall, eliminating the need for a separate lock and Bowden cable by engaging directly or indirectly with the storage box outer wall, allowing the cab door to cover and lock it when closed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate lock and Bowden cable are installed on the storage box, then the storage box can be securely locked, but the device complexity and cost increase
Solution Approach 1:
The patent combines the locking function of the storage box with the existing cab door mechanism. The cab door's latch mechanism is integrated to also secure the storage box, eliminating the need for a separate locking system. This merging of functions reduces device complexity while maintaining security.
Solution Approach 2:
The cab door is given a dual function: it serves as both an access door to the driver's cabin and as a locking mechanism for the storage box. By making the door universal, the patent eliminates the need for dedicated lock components on the storage box, thereby reducing complexity.
2Reliability
If a separate lock and Bowden cable are installed on the storage box, then the storage box can be securely locked, but the manufacturing cost increases
Solution Approach 1:
The patent merges the storage box locking function with the existing cab door mechanism, eliminating the need to manufacture separate lock components and Bowden cables for the storage box. This reduces the number of parts that need to be manufactured and assembled, thereby lowering manufacturing costs.
Solution Approach 2:
The patent discards the idea of adding dedicated locking components to the storage box, instead recovering and reusing the existing cab door latch mechanism for dual purposes. This approach eliminates the cost of additional locking components while maintaining security functionality.
3Reliability
If the cab door covers the storage box outer wall, then the storage box is secured against opening, but the storage box accessibility is reduced
Solution Approach 1:
The patent implements a dynamic locking system where the cab door's position determines the storage box's accessibility. When the cab door is closed, the storage box is automatically locked. When the cab door is opened, the storage box can be accessed. This dynamic behavior provides both security and ease of operation.
Solution Approach 2:
The cab door's closing action preliminarily secures the storage box before the driver even approaches it. The locking mechanism is activated in advance by the door's position, ensuring security is maintained without requiring additional locking actions from the user.

AI summary
The invention relates to a side wall (10) for the cab of a commercial vehicle. The side wall (10) comprises a cab door (1) and a storage box (2) arranged laterally next to the cab door (1), which serves for stowing cargo and has a preferably pivotable storage box outer wall (3). The side wall (10) is characterized in particular by the fact that, when the cab door (1) and the storage box outer wall (3) are closed, the cab door (1) partially covers the storage box outer wall (3) and thus secures it against opening.
