Furniture Flap Fitting With Spring-Preload Release Opening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture flap fittings are cumbersome to open, especially for handleless designs, and lack efficient mechanisms to balance the weight of the flap during opening.
Innovation Solution
A fitting arrangement with a locking mechanism and retaining bracket that holds the flap in a closed position using a spring element introducing a preload in the opening direction, assisted by a tension spring for easy opening, and a release mechanism to unlock the blockage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a locking mechanism with spring preload is used to hold the flap in closed position, then the reliability of closed position is improved, but the ease of operation deteriorates due to the holding force that must be overcome to open
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic release state through the release mechanism. The spring element dynamically adjusts the holding force, and the release mechanism provides a dynamic transition path that overcomes the static friction and spring preload to enable easy opening while maintaining reliable closed position holding.
Solution Approach 2:
The release mechanism acts as an intermediary between the user and the locking mechanism. Instead of directly overcoming the spring preload, the user activates the release mechanism which mediates the force application, allowing easy opening while maintaining the reliability of the closed position through the spring element's controlled engagement and disengagement.
2Ease of operation
If a spring element introduces preload in the opening direction to assist opening, then the ease of operation is improved, but the device complexity increases due to additional spring elements and adjustment mechanisms
Solution Approach 1:
The spring element serves multiple functions: it provides the holding force to maintain the closed position, assists in the opening direction to reduce user effort, and works with the release mechanism to enable controlled transitions. This multi-functionality reduces the need for separate mechanisms, thereby managing complexity while improving ease of operation.
Solution Approach 2:
The spring element's preload can be adjusted to optimize performance for different flap weights and opening requirements. By changing the spring force parameter, the system adapts to different operational conditions, providing ease of opening without requiring a completely different mechanism for each application scenario.
3Adaptability or versatility
If the spring force is made adjustable to accommodate different flap weights, then the adaptability is improved, but the device complexity increases due to adjustment mechanisms
Solution Approach 1:
The adjustment mechanism is pre-configured to allow easy modification of the spring force for different flap weights. The adjustment can be performed during installation or maintenance without requiring complex disassembly or specialized tools, enabling the system to adapt to different applications while keeping the adjustment process simple and the overall device complexity manageable.

AI summary
The invention relates to a fitting arrangement with a furniture fitting, in particular a flap holder, with which a furniture flap or a door can be pivotably attached to a furniture body, wherein a locking mechanism (200) and a retaining device (300) are provided, with which the furniture flap can be connected to the furniture body in a force-locking and/or form-locking manner in a closed position of a kinematic arrangement (30) of the furniture fitting, wherein the kinematic arrangement (30) has levers and joints by means of which the furniture flap or door can be moved from the closed position to an open position, wherein a spring element (38.2) is provided which, in the closed position of the kinematic arrangement (30), introduces a preload into the kinematic arrangement (30) in the opening direction, and wherein the locking mechanism (200) and the retaining bracket (300) form a release mechanism with which the connection between the locking mechanism (200) and the retaining bracket (300) can be released in the closed position of the kinematic arrangement. With such a fitting arrangement, a convenient opening of a door or flap from the closed position can be effected.
