Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture fittings for movable storage face challenges such as increased material and cost due to complex designs, limited adjustment range, and structural complexity, particularly in compact designs where space is constrained.
Innovation Solution
A furniture fitting with a fastening device featuring a rotatable screw actuating element that allows for secure fastening at both ends of the housing, using a locking mechanism with inclined surfaces for non-positive connection and adjustable positioning, enabling reliable attachment to furniture bodies and movable parts without significant material excess or complexity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an L-shaped second fitting part is used to accommodate the joint axes, then the fitting can be assembled, but material expenditure and costs increase
Solution Approach 1:
The fitting part is divided into two separate components: a first fitting part with a first joint axis and a second fitting part with a second joint axis. These segmented parts are connected through a connection element, eliminating the need for a complex L-shaped monolithic structure and reducing material expenditure.
Solution Approach 2:
The first fitting part is received within a first recess and the second fitting part is received within a second recess, with both fitting parts and their respective recesses nested within the furniture body. This nesting arrangement accommodates the joint axes without requiring excessive material.
2Ease of manufacture
If an L-shaped second fitting part is used, then the joint axes can be positioned, but the design becomes voluminous and compactness is compromised
Solution Approach 1:
By segmenting the fitting into separate first and second fitting parts with distinct joint axes, each part can be compactly positioned within its own recess, avoiding the voluminous L-shaped configuration while maintaining proper joint axis positioning.
Solution Approach 2:
The joint axes are arranged in different spatial dimensions and orientations - the first joint axis in the first fitting part and the second joint axis in the second fitting part, connected through a connection element. This dimensional arrangement achieves proper positioning without requiring a voluminous L-shaped structure.
3Reliability
If an eccentric mechanism is used for fastening, then the fitting part can be secured, but the adjustment range is limited and recess size must be precisely matched
Solution Approach 1:
The fastening mechanism uses a movable fastening element that can be positioned at multiple locations along the connection element, providing dynamic adjustability. This allows the fitting to accommodate various recess sizes and positions while maintaining reliable fastening, unlike the fixed-range eccentric mechanism.
Solution Approach 2:
A connection element serves as an intermediary between the first and second fitting parts, with a fastening element that can be positioned at different locations. This intermediary mechanism provides versatile adjustment range and adapts to different recess dimensions without requiring precise size matching.
4Reliability
If a handle pivot mechanism is used to press the bracket body, then the hinge can be secured, but the design becomes relatively complex
Solution Approach 1:
The fitting is segmented into distinct first and second fitting parts with separate fastening mechanisms, each independently secured within its own recess. This segmentation simplifies the overall design compared to a complex integrated handle pivot mechanism, while maintaining reliable securing functionality.
Solution Approach 2:
A connection element acts as an intermediary between the first and second fitting parts, with a fastening element that provides the securing mechanism. This intermediary approach creates a simpler design compared to the handle pivot mechanism, while achieving reliable fastening through the movable fastening element.
