Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing covering devices for hollow profile elements in furniture construction are not adaptable to different wall material thicknesses, requiring multiple variations to securely attach and prevent dirt entry, which increases manufacturing costs and complexity.
Innovation Solution
A covering device with multiple detent elements of varying sizes that can engage with different wall thicknesses, featuring a plate-like basic body with resiliently connected detent elements and block-shaped projections for secure, friction-locking attachment, allowing for universal fitment across various wall elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a covering device is designed to match a specific wall thickness closely, then it can be attached securely and prevent dirt entry, but it cannot be used with wall elements of different thicknesses, requiring multiple variations
Solution Approach 1:
The covering device incorporates multiple detent elements with different engagement geometries on a single device, enabling it to securely attach to wall elements of various thicknesses. Each detent element is configured to engage with walls of specific thickness ranges, providing universal compatibility across different furniture components without requiring multiple specialized covering devices.
Solution Approach 2:
Different regions of the covering device feature detent elements with locally optimized properties - each detent element has specific engagement characteristics suited for particular wall thicknesses. This local differentiation allows the single covering device to adapt to varying wall thicknesses while maintaining secure attachment and proper sealing at each engagement point.
2Reliability
If multiple variations of covering devices are produced for different wall thicknesses, then each can be optimized for its specific application, but manufacturing expense and costs increase
Solution Approach 1:
Multiple detent elements that would traditionally require separate covering devices are merged into a single integrated component. This consolidation allows one covering device to perform the function of multiple specialized devices, reducing manufacturing complexity, inventory requirements, and production costs while maintaining optimized attachment capabilities for different wall thicknesses.
Solution Approach 2:
By designing a universal covering device that incorporates multiple detent elements for different wall thicknesses, the manufacturer produces a single multi-functional component that replaces several single-purpose devices. This approach reduces overall manufacturing expense by eliminating the need to produce, store, and distribute multiple variations of covering devices.
3Object-affected harmful factors
If the covering device is made to fit tightly to prevent dirt entry, then sealing performance improves, but the design becomes more complex and harder to manufacture
Solution Approach 1:
The sealing function is segmented into multiple detent elements, each responsible for engagement with walls of specific thicknesses. This segmentation allows each element to be relatively simple in design while collectively providing comprehensive sealing across different wall thicknesses, avoiding the need for a single complex adaptive mechanism.
Solution Approach 2:
Each detent element is designed with local quality optimized for its specific engagement purpose, creating simple, effective sealing at each contact point. This localized optimization approach maintains simplicity in each individual element while achieving comprehensive dirt prevention across various wall thicknesses through the combination of multiple elements.

Function Achieved in This Case
The solution provides a secure, space-efficient, and cost-effective means to cover apertures on furniture elements by accommodating different wall thicknesses, ensuring complete closure and preventing dirt entry while maintaining a flush, visually inconspicuous design.
Implementation Method 1
one of the detent elements is connected resiliently pliable to the basic body parallel to a first covering surface of the basic body which is provided for an arrangement facing the wall element
Implementation Method 2
with the action of a ram press the contact bearing surface against an edge of the aperture in order to secure the covering device against the aperture with friction-locking engagement

AI summary
A covering device is proposed for a surface side of a wall element, more particularly a side rail of a drawer, with which an aperture in the surface side of the wall element can be covered wherein the covering device has attachment means with which the covering device can be attached to the aperture. According to the invention the attachment means comprise several detent elements which are different from one another wherein the different detent elements are adapted for engagement on different wall thicknesses.
