Furniture Hinge Resilient Device Mounting Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing furniture hinges lack stability during assembly as the resilient device is not securely positioned, leading to potential misalignment and instability in the hinge mechanism.
Innovation Solution
A furniture hinge design that includes an arm member, casing, inner and outer links, and a resilient device with specific mounting structures and resilient members, allowing the resilient device to be securely positioned at assembly, ensuring stability through a double-layer resilient structure and cap guidance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the resilient device is not secured at a predetermined position during assembly, then the assembly process is simpler, but the stability and alignment of the hinge mechanism deteriorates
Solution Approach 1:
The resilient device is pre-secured to the arm member at a predetermined position using a mounting structure (projection and recess) before the actual hinge assembly takes place. This preliminary positioning ensures that when the hinge components are assembled, the resilient device is already in the correct location and orientation, maintaining stability and alignment throughout the assembly process while keeping the process straightforward
2Stability of the object's composition
If the resilient device is secured at a predetermined position using mounting structures, then the stability and alignment of the hinge mechanism is improved, but the device complexity increases
Solution Approach 1:
The mounting structure is divided into two separate segments: a projection formed on the arm member and a corresponding recess formed on the resilient device. This segmentation allows each component to be manufactured independently with its own mounting feature, simplifying the overall design while ensuring stable positioning when the segments are assembled together
Solution Approach 2:
The projection of the arm member and the recess of the resilient device combine to form a unified mounting connection. This merging of two simple features creates a stable positioning system that is more effective than either feature alone, achieving reliable positioning without requiring complex mounting mechanisms

AI summary
A furniture hinge (20) includes an arm member (28), a casing (30), an inner link (42), an outer link (44), and a resilient device (46). The arm member (28) includes at least one wall (38a, 38b, 38c). The at least one wall (38a, 38b, 38c) includes a first mounting structure (36). The casing (30) can be opened and closed with respect to the arm member (28). Each of the inner link (42) and the outer link (44) has two end portions (48a, 50a; 48b, 50b) respectively and pivotally connected to the arm member (28) and the casing (30) via shafts (72, 76; 74, 78). The resilient device (46) provides a resilient force acting between the casing (30) and the arm member (28) and includes a second mounting structure (52) to be mounted to the first mounting structure (36).
