Deformable Guide Wire Hinge for Stow Box Door Warping Loads
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stow box door hinge systems lack flexibility, leading to excessive load transmission to latching and mounting points, which can cause deformation and prevent the door from operating properly during dynamic tests, such as pitch and roll warping, and are cumbersome due to multiple parts increasing cost, weight, and assembly time.
Innovation Solution
A deformable guide wire hinge system with a unitary guide wire and anchoring structures, including a blind retention hole and undercut retention structure, allows the hinge to absorb stresses by bending and returning to its original shape, reducing load on latching points and eliminating the need for additional fastening hardware.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a conventional piano hinge system is used, then the door can hold loads for normal operation, but the system lacks flexibility and transmits excessive loads to latching and mounting points
Solution Approach 1:
The hinge system changes the physical state of the guide wire from rigid to deformable under load. The guide wire is designed to yield and deform plastically when subjected to excessive loads during dynamic events, absorbing energy and preventing load transmission to mounting points. This parameter change allows the hinge to adapt its stiffness based on the applied load conditions.
2Reliability
If multiple hinge halves and pins with multiple hardware pieces are used, then the door can be securely attached, but the system becomes cumbersome with increased cost, weight, and assembly time
Solution Approach 1:
The invention merges multiple separate hinge components (hinge halves, pins, and fastening hardware) into a single integrated guide wire component. The guide wire serves multiple functions simultaneously: it acts as the hinge pivot, the attachment fastener, and the load-bearing element. This consolidation eliminates the need for multiple separate parts while maintaining secure attachment through the unitary structure with integrated retention features.
3Stability of the object's composition
If a rigid hinge system is used, then the structure is stable, but excessive loads during warping can cause deformation and prevent door operation
Solution Approach 1:
The hinge system transitions from a static rigid structure to a dynamic deformable system. The guide wire is designed to deform elastically during normal operation to maintain stability, but can yield plastically during extreme dynamic events to absorb energy. This dynamic behavior allows the hinge to adapt its structural response based on the intensity of applied loads, maintaining operability after dynamic tests.
