Spring-Loaded Overload Mechanism for Anti-Toppling Imaging Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices with extendable arms, such as skin detection devices, face challenges in passing safety tests due to the need to support weights over 80 kilograms without toppling, leading to increased device size and weight, which occupies more space.
Innovation Solution
An overload protection mechanism comprising a first accommodating member, a second accommodating member, a force storage member, and an object, where the second accommodating member is rotatably disposed on the first accommodating member, and the force storage member is connected between them, allowing the object to rotate when external torque exceeds the torque provided by the force storage member, preventing the device from toppling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the size of the host device is increased to pass safety tests, then the device can bear weight over 80 kilograms without toppling, but the device becomes heavier and occupies more space
Solution Approach 1:
The patent applies the dynamics principle by replacing the static, oversized host device structure with a dynamic overload protection mechanism. The mechanism includes a force storage member (spring) that dynamically responds to applied loads, allowing the device to adapt its structural response based on the magnitude of external forces. This enables the device to maintain stability under normal operating conditions while preventing damage during overload events, without requiring a permanently oversized structure.
Solution Approach 2:
The patent implements beforehand cushioning by incorporating a force storage member (spring) that is pre-configured to absorb and dissipate excessive forces before they can cause damage to the device. The spring is positioned in advance to counteract potential overload conditions, providing protective cushioning that prevents the device from toppling under extreme loads without requiring the device to be designed for maximum possible loads from the outset.

3Reliability
If the torque provided by the force storage member is increased to prevent toppling, then the device stability improves, but the mechanism becomes more complex
Solution Approach 1:
The patent applies the self-service principle by designing a mechanism where the force storage member (spring) automatically adjusts and regulates the torque provided to counteract external forces. The spring's inherent elastic properties enable it to self-regulate the protective torque based on the magnitude of applied loads, eliminating the need for complex external control systems, sensors, or actuators. The mechanism serves itself by utilizing the physical properties of the spring to provide appropriate counter-torque without requiring additional complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism effectively prevents devices from toppling due to overload by adjusting the torque provided by the force storage member, allowing the device to remain stable while reducing the need for excessive size and weight, thus optimizing space usage.
Implementation Method 1
the force storage member is disposed between the first accommodating member and the second accommodating member. Opposite ends of the force storage member are connected to the first accommodating member and the second accommodating member

AI summary
An overload protection mechanism includes a first accommodating member, a second accommodating member, a force storage member, and an object. The second accommodating member is rotatably disposed on the first accommodating member. The force storage member is disposed between the first accommodating member and the second accommodating member. Opposite ends of the force storage member are connected to the first accommodating member and the second accommodating member. The object is connected to the second accommodating member. When an external force is exerted on the object and a torque generated by the external force is larger than a torque provided by the force storage member, the external force forces the object to drive the second accommodating member to rotate with respect to the first accommodating member.
