Van Cabinet Drawer Stops With Vibration-Damping Guide Structure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing van cabinets face issues with high production costs, complex construction, long mounting times, difficulty in coupling with other modules, and failure to absorb vibrations, leading to safety concerns and noise due to loose drawers during travel.
Innovation Solution
A cabinet with a box-like support structure and guides made from plastic material, featuring a projecting edge for drawer stops and elastic components to absorb vibrations, allowing easy access and simple mounting, while maintaining structural integrity and reducing noise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If telescopic guides with C-shaped profiles and hooks are used to support drawers, then drawer support reliability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent extracts the essential function of drawer support from the complex telescopic guide mechanism and implements it through a simpler structure: drawers rest directly on the base panel without requiring complex guides, hooks, or C-shaped profiles. This extraction eliminates unnecessary complexity while maintaining the core support function.
Solution Approach 2:
The patent replaces expensive, complex metallic telescopic guides with simpler, more cost-effective components. The base panel directly supports drawers using basic structural elements rather than precision-engineered guide mechanisms, reducing manufacturing costs while maintaining adequate functionality.
2Reliability
If telescopic guides are fixed to uprights through rivets, then drawer support stability is improved, but mounting time increases
Solution Approach 1:
The patent removes the complex fixation system involving rivets and multiple attachment points. Instead, drawers are supported directly by the base panel structure, eliminating the need for extensive fixing operations and reducing assembly time significantly.
3Reliability
If telescopic guides are installed on both sides of the metallic structure, then drawer guidance is improved, but difficulty in coupling with other modules increases
Solution Approach 1:
The patent extracts the drawer guidance function from the side-mounted telescopic guides and integrates it into the base panel structure. This simplification removes the lateral guides that would interfere with coupling other modules to the cabinet structure, while drawers remain properly guided through their interaction with the base panel and stop devices.
4Ease of operation
If drawers are supported by telescopic guides without vibration deadening, then drawer accessibility is improved, but safety decreases due to vibrations causing stops to release
Solution Approach 1:
The patent implements vibration deadening measures in advance by incorporating elastic elements and friction-based retention mechanisms into the drawer support system. The rough base panel surface and friction-based stops are designed beforehand to counteract vibrations during vehicle movement, preventing unintended drawer opening while maintaining easy accessibility.

AI summary
Cabinet (1) for vans, which comprises: a support structure (3) able to be fixed inside a van; a plurality of drawers (2) able to be inserted inside spaces (4) defined by the support structure (3) and able to be made to slide along a sliding direction (X) between a closed position thereof and a first open position thereof; a plurality of guides (14) fixed to the support structure (3), which guide the drawers (2) to slide along their sliding direction (X). Moreover, the support structure (3) is equipped with a projecting edge (34) from the front profile of the spaces (4) of the support structure (3), said projecting edge (34) delimiting the access of the drawers (2) to the spaces (4) themselves. Each drawer (2) is provided with a stop device (44), which is mounted on the front wall (10) of the drawer (2) itself, and comprises a control body (44') able to be made to move between a raised position, in which a projection (46) of the control body (44') engages with the projecting edge (34) to stop the drawer (2) in the closed position, and a lowered position in which the projection (46) is disengaged from the projecting edge (34) to allow the drawer (2) to open. Each drawer (2) is also equipped with a stop portion (64) arranged at its rear wall (11), said stop portion (64) projecting at the top from the drawer (2), and being able to go into abutment against the projecting edge (34) to stop the sliding of the drawer (2) in its first open position.
