Pivoting-Element Fitting for Tool-Free Damping Position Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fittings for pivoting elements require complex mechanisms to transition between damping positions, leading to increased production effort, costs, and susceptibility to defects, while also being visible and unsuitable for invisible designs.
Innovation Solution
A damping device is arranged in a fitting part with a locking mechanism that allows transfer between damping positions using orthogonal movements of engagement and locking elements, facilitated by a deflection device and an actuating element, which can be tool-free or tool-operated, ensuring a visually appealing and functional design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a complex mechanism is used to transfer the damping device between damping positions, then the damping device can be transferred between positions, but the production effort and costs increase
Solution Approach 1:
The locking device is divided into separate functional elements: a locking element that can be actuated independently, and an engagement element that interacts with it. This segmentation allows the damping device to be transferred between positions through a simplified two-step process rather than a complex integrated mechanism.
Solution Approach 2:
The locking element is designed to be movable between a release position and a locking position, enabling dynamic reconfiguration of the damping device's position. This dynamic capability allows easy transfer between damping positions without requiring complex mechanical linkages.
2Adaptability or versatility
If a complex mechanism is used to transfer the damping device between damping positions, then the damping device can be transferred between positions, but the susceptibility to defects increases
Solution Approach 1:
By separating the locking function into an independent locking element that can be actuated without tools, the mechanism becomes more reliable. There are fewer interconnected parts that could fail, and the simplified structure reduces potential defect points while maintaining the ability to transfer between damping positions.
3Shape
If fitting components are arranged completely within the stationary element or pivoting element for invisible design, then the fitting becomes invisible, but the damping device cannot be transferred between positions
Solution Approach 1:
The locking and engagement elements are arranged within the fitting structure in a nested configuration. The locking element can be actuated from the outside to move between positions, while the engagement element remains integrated within the fitting components. This nesting allows the fitting to maintain a clean, invisible appearance when closed while still enabling damping device transfer.
Solution Approach 2:
The locking element acts as an intermediary that bridges the external actuation and the internal damping device. It can be moved by external force to engage or disengage the damping device, enabling position transfer without requiring visible mechanical linkages or complex external mechanisms.
4Reliability
If a locking element is moved from release position to locking position, then the damping device can be held in the second damping position, but the locking element must be movable in a first direction
Solution Approach 1:
The locking mechanism is segmented into a locking element with defined movement capability in a first direction, and an engagement element that responds to this movement. This segmentation simplifies the overall mechanism while ensuring reliable positioning, as each element has a clear, limited function rather than requiring complex coordinated movement.
Solution Approach 2:
The locking element moves in a first direction to engage the engagement element, while the engagement element then moves the locking element in a second direction orthogonal to the first. This two-dimensional movement sequence simplifies the locking mechanism compared to requiring complex three-dimensional coordination, while still achieving stable positioning.
