Solution Overview
Problem
Existing methods for coupling and decoupling objects, such as panels and circuit boards, require loosening screws and manual removal, lacking a mechanism for ease of use and quick coupling.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to couple two objects, then the coupling strength is improved, but the ease of operation deteriorates due to requiring screw loosening and manual removal
Solution Approach 1:
The coupling mechanism is divided into separate functional components: a connecting element with fixing portions for attachment, a handle for operation, and a positioning element with corresponding portion for engagement. This segmentation allows the strong screw-like fixing to be controlled by a simple handle operation rather than requiring manual screw manipulation.
Solution Approach 2:
The positioning element acts as an intermediary between the handle and the connecting element. When the positioning element engages with the corresponding portion of the connecting element, it translates the handle's rotational or linear motion into the engagement/disengagement of the fixing portions, providing mechanical advantage and ease of operation.
2Ease of operation
If direct latching is used to fix objects, then the ease of operation is improved, but the reliability deteriorates due to lack of secure fastening
Solution Approach 1:
The invention merges the simplicity of direct latching with the security of threaded fastening. The connecting element combines a latch-like structure with fixing portions that provide secure attachment, while the handle provides the mechanical advantage needed for reliable engagement. This hybrid approach achieves both ease of operation and fastening reliability.
Solution Approach 2:
The elastic element introduces a curved, flexible component into the otherwise rigid coupling mechanism. This elasticity allows the connecting element to deform slightly during engagement, ensuring reliable contact between the fixing portions and the objects being coupled, thereby improving fastening reliability while maintaining ease of operation.
3Ease of operation
If an elastic element is added to the connecting element, then the ease of operation is improved through automatic release, but the device complexity increases
Solution Approach 1:
The elastic element enables the connecting element to automatically return to its initial state after engagement. When the handle is released, the elastic element's restoring force automatically pushes the connecting element back, causing the fixing portions to disengage without requiring manual intervention. This self-service mechanism improves ease of operation while adding minimal complexity since the elastic element is integrated into the existing connecting element structure.
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
Enables quick and easy coupling and decoupling of objects by using an elastic element to automatically release the handle, facilitating efficient assembly and disassembly without the need for screw loosening.
Implementation Method 1
The connecting element has an elastic element. The elastic element has two ends disposed at the handle and the connecting element, respectively. as soon as the positioning element escapes from the connecting element, the handle escapes from the connecting element and thus rotates or moves

AI summary
A pull aid structure includes a handle; a connecting element movably disposed at the handle; and a positioning element disposed at the handle and movably coupled to the connecting element. The pull aid structure enables a user to place the connecting element on an object, rotate the handle to fasten another object, confine the positioning element to the connecting element, and compress an elastic element, so as to couple together the two objects. To remove one of the objects, the user separates the positioning element and the connecting element to thereby separate the two objects, thereby achieving quick coupling and ease of removal.
