Inclined shelf case
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inclined shelf cases with pullout shelves face challenges in assembly and spring device handling, leading to increased effort and risk of injury or damage due to high-speed movement and disarray of goods, especially when refilling or cleaning.
Innovation Solution
The design incorporates a connection element with a first and second connection section for the spring device, allowing automatic engagement with the shelf body during assembly, reducing manual effort and providing ample space for handling, along with a movable stop element to maintain the shelf open during filling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spring devices with sufficient spring force are used to brake a completely filled inclined shelf, then the shelf moves against the end stop at a greatly reduced speed, but an inclined shelf filled only in part or not filled yet does not remain in a pulled out position when being pulled out
Solution Approach 1:
The patent employs a magnet system that generates a magnetic field to hold the inclined shelf in position. The magnetic force parameter is adjusted to provide sufficient holding force for partially filled shelves while allowing the spring device to provide adequate braking for fully loaded shelves. This parameter-based solution resolves the contradiction by using different physical mechanisms (magnetic holding vs. spring braking) for different loading conditions.
2Ease of operation
If the spring device is detached from the shelf body or the inclined shelf prior to removal for cleaning, then the inclined shelves can be completely removed, but it is difficult to fasten the spring device to the shelf body or the inclined shelf in a manner that the functionality of the spring device is given
Solution Approach 1:
The patent divides the connection system into separate magnetic connection elements that can be independently attached to either the shelf body or the inclined shelf. This segmentation allows the spring device to be completely removed for cleaning while simplifying reassembly, as the magnetic elements can be easily reattached without complex fastening procedures.
Solution Approach 2:
The patent replaces traditional mechanical fastening systems with a magnetic connection system. The magnet elements provide secure attachment during normal operation but allow for easy separation and reattachment, eliminating the difficulty of fastening spring devices while maintaining full removability for cleaning purposes.
3Ease of operation
If the user has to reach between the inclined shelves to fasten the spring device to the shelf body, then more space for handling the spring device is required, but it is necessary to tension the spring more strongly, resulting in an increased effort when fastening the spring device
Solution Approach 1:
The patent replaces the mechanical spring tensioning process with a magnetic attachment system. The magnet elements are simply attached to the shelf structure without requiring strong spring tensioning or difficult manual manipulation, dramatically reducing the effort required during assembly while maintaining adequate handling space.
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
Simplifies the assembly and refilling process by automating the connection of the spring device and maintaining the shelf open, reducing the risk of injury and damage, while minimizing the effort required for spring tensioning and ensuring stable operation.
Implementation Method 1
spring devices are often provided that act between the shelf body and the inclined shelf and brake the inclined shelf when being pulled out
Implementation Method 2
spring devices, which may be designed as rubber bands, for example, have sufficient spring force to brake a completely filled inclined shelf
Implementation Method 3
when the lowermost object is taken out, the remaining objects move down due to the effect of gravity so that there always is one object in the take-out position

AI summary
The invention relates to an inclined shelf case having a shelf body having at least one inclined shelf which drops away to the take-out side and has an abutting element holding a placed object on the bottom end thereof, wherein the at least one inclined shelf is held to the shelf body via guide rails and is designed as a pull-out running on the guide rails which can be pulled out to the take-out side and having a spring device for decelerating the inclined shelf during the pull-out, which operates between the shelf body and the inclined shelf. According to the invention the spring device has a connection element which has a first connection section, which is connected to the shelf body in an operating position by means of a holder , and which has a second connection section, and the inclined shelf has a fastening holder to which the connection element is fastened via the second connection section in an assembly position, wherein, upon pushing in the inclined shelf with the connection element in the assembly position, the first connection section engages on the holder and wherein the second connection section is removable from the fastening holder.
