Adjustable Spring Buffer for Handleless Furniture Front Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Furniture assembly is complicated by the need for varying activating distances in movable furniture parts without handles, and ensuring a uniform frontal surface becomes challenging, especially with multiple furniture items or parts.
Innovation Solution
Incorporating a spring buffer that provides a consistent activating distance between furniture parts and the body, allowing for adjustable play to ensure uniformity and ease of assembly, which can be retrofit into existing furniture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If allowance is made for movement of the movable furniture part from the closed stop position towards the furniture body to enable ejection device activation, then the ejection device can be triggered, but the frontal surface becomes non-uniform and assembly becomes more difficult
Solution Approach 1:
A spring buffer is introduced as an intermediary element between the movable furniture part and the furniture body. The spring buffer absorbs the movement required for ejection device activation while maintaining a uniform frontal surface appearance. It acts as a mediator that enables the triggering function without compromising the aesthetic uniformity or simplifying the assembly process.
Solution Approach 2:
The spring buffer is pre-installed on the furniture body to counteract the movement issue before assembly. By providing preliminary compensation for the activating distance, the spring buffer prevents the need for additional adjustment during assembly, thereby maintaining uniform frontal surfaces while enabling ejection device activation.
2Adaptability or versatility
If varying activating distances are accommodated for different movable furniture parts, then each part can function properly, but the frontal surface uniformity is compromised
Solution Approach 1:
The spring buffer allows for parameter changes in activating distance while maintaining a constant frontal surface appearance. By adjusting the spring buffer's compression characteristics or pre-compression force, different activating distances can be achieved without affecting the uniformity of the frontal surface across multiple furniture parts.
3Ease of operation
If sufficient play is left for the movable furniture part in its closed end position to enable ejection device triggering, then the ejection function works, but the assembly process becomes more complex
Solution Approach 1:
The spring buffer is pre-installed and pre-configured on the furniture body before the movable furniture part is assembled. This preliminary action ensures that the required play for ejection device triggering is already in place, eliminating the need for complex adjustments during the final assembly process while maintaining full ejection functionality.

AI summary
A spring buffer for a furniture item has a furniture body and a furniture part movable from a closed position in or on the furniture body. The spring buffer can be arranged relative to the furniture body and the furniture part such that the movable furniture part in its closed end position can be moved against the force of the spring buffer towards the direction of the furniture body. The spring buffer includes a buffer element for the movable furniture part and the buffer element is acted upon by a spring. The buffer element is movably arranged such that the distance covered by the buffer element against the force of the spring can be changeably adjusted.
