Clip Hinge Structure That Holds the Lid Upright in Tight Spaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing clips with hinge structures face difficulties in maintaining an open state, especially in narrow spaces, leading to interference with surrounding parts and making it challenging to attach or remove busbars, particularly when multiple clips need to be operated simultaneously.
Innovation Solution
A hinge structure with a pin and socket configuration, featuring an interference part with a long and short side, and a socket with a recess, allowing the lid to be held upright and securely open relative to the body, and additional restricting surfaces to regulate movement and prevent rattling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the clip is fixed in a narrow, recessed part of an automobile body, then the clip can be installed in confined spaces, but the clip cover cannot be held in an open state and may interfere with surrounding parts
Solution Approach 1:
The hinge structure automatically holds the lid in an open state through its mechanical design (pin with interference part fitting into socket with recess), eliminating the need for manual intervention to maintain the open position during busbar installation in narrow spaces
2Ease of operation
If the operator manually holds the clip lid open, then the lid can remain open for busbar attachment, but it becomes difficult when multiple clips need to be operated simultaneously
Solution Approach 1:
The hinge structure autonomously maintains the lid in an open state through its mechanical configuration, allowing operators to work on multiple clips simultaneously without needing to manually hold each lid open, thereby improving overall productivity
3Ease of operation
If the clip lid is held open manually, then busbar attachment is possible, but the operator may not be able to reach narrow parts to hold the lid
Solution Approach 1:
The hinge structure self-maintains the lid in an open position through its mechanical design, eliminating the need for operator intervention to hold the lid open in difficult-to-reach narrow spaces, thus improving accessibility
4Ease of operation
If the lid is freely movable on the hinge, then the lid can open and close smoothly, but the lid may rattle and cannot be held in a specific position
Solution Approach 1:
The pin features an asymmetric interference part with distinct long and short sides, while the socket has corresponding asymmetric recesses, creating specific engagement positions that provide stable positioning while allowing smooth rotational movement between defined states

AI summary
A clip for securing an element to a larger assembly. The clip comprises a body, a lid, and a hinge for rotatably connecting the lid to the body. The hinge defines a hinge axis and includes a pin and a socket. The pin includes an interference part comprising a long side and a short side. The socket defines a hole having a long side and a short side and surrounds the interference part of the pin. The hole's short side being shorter than the long side of the pin, and the hole's long side defining a recess. The lid can be opened and closed relative to the body. When the lid is opened to an upright position relative to the body, the short side of the interference part of the pin fits into the recess of the hole of the socket so that the lid is held upright.
