Metal Coil Deposition Stabilization via Third Support Point
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for depositing metal coils with high residual stress often result in unstable equilibrium, leading to off-center deposition and potential spring-up or lifting off the coil buggy, posing risks during handling and transportation.
Innovation Solution
A method that checks for unstable equilibrium by evaluating criteria such as diameter, thickness, strength, temperature, and load distribution, and optionally uses a third displaceable support point to stabilize the coil, placed against the outer circumference to counteract instability and residual stress.

Engineering Contradiction Analysis
1Device complexity
If a metal coil with high residual stress is deposited on two stationary support points, then the device structure is simple, but the coil deposition becomes unstable and may spring up or lift off
Solution Approach 1:
The invention converts the static two-support-point system into a dynamic three-support-point system. The third support point is movable and can be adjusted radially outward to engage with coils having high residual stress, providing additional stabilization. This dynamic adaptation allows the same device to handle both stable and unstable coils effectively.
Solution Approach 2:
The invention changes the geometric parameters of the support system by adding a third support point that can be positioned at different radial distances from the coil center. By adjusting the position of this third support point, the device adapts to different coil conditions (stable vs. unstable), preventing spring-up and lift-off while maintaining structural simplicity.
2Reliability
If three support points are always used for metal coil deposition, then the coil deposition stability is improved, but the device occupies unnecessary large space for coils without high residual stress
Solution Approach 1:
The third support point is designed to be movable rather than fixed, allowing it to be retracted to a compact position when not needed. This dynamic configuration enables the device to maintain a small footprint during normal operation while expanding to provide three-point support only when required for unstable coils.
Solution Approach 2:
The invention extracts the third support point from a permanently integrated configuration and makes it a separate, movable component. This allows the support point to be deployed only when necessary for stabilizing coils with high residual stress, avoiding the continuous space occupation that would result from a fixed three-support-point design.
3Reliability
If the third support point is placed radially outward, then the stabilization effect against spring-up is enhanced, but the device complexity increases
Solution Approach 1:
The third support point is designed to move along a radial path outward from the coil center, following the curved surface geometry. This radial movement pattern simplifies the positioning mechanism compared to arbitrary 2D or 3D positioning, as it constrains the motion to a single degree of freedom along the radius, reducing mechanical complexity while maintaining effective stabilization.
