Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional connection methods are used for splicing LED boxes and lifting beams, then the connection can be achieved, but the splicing process is inconvenient and inefficient
Solution Approach 1:
The connection apparatus is divided into modular components: connecting seats with receiving holes, connecting shafts with clamping holes, and locking components with clamping protrusions. Each part can be independently manufactured and assembled, enabling rapid splicing of LED boxes and lifting beams without complex integrated structures.
Solution Approach 2:
The locking component features self-locking through the interaction of clamping protrusions and clamping holes. When the connecting shaft is inserted into the receiving hole, the locking component automatically engages through its protrusions fitting into the holes, eliminating the need for additional fastening operations or tools during splicing.
2Adaptability or versatility
If the gap between adjacent LED boxes needs to be adjusted, then connection flexibility is improved, but the connection structure becomes more complex
Solution Approach 1:
The connecting shaft can rotate within the receiving hole, and the locking component can be rotated to different positions. This dynamic capability allows the gap between adjacent LED boxes to be adjusted by rotating the connecting shaft to different angular positions, providing flexibility without requiring complex adjustable mechanisms.
Solution Approach 2:
The clamping protrusions are positioned asymmetrically on the locking component, allowing selective engagement with corresponding holes at different rotational positions. This asymmetric design enables gap adjustment by rotating the locking component to different orientations, maintaining structural simplicity while achieving adaptability.
3Ease of operation
If a lifting beam splicing system is designed to match box length, then transportation and lifting are facilitated, but the splicing process becomes cumbersome
Solution Approach 1:
The connecting seats are pre-configured with receiving holes and clamping features during manufacturing. When splicing lifting beams, the connecting shafts are pre-aligned with the receiving holes, and the locking components are ready to engage immediately upon insertion, eliminating the need for on-site adjustments or complex alignment procedures.
Solution Approach 2:
Traditional mechanical fastening systems requiring multiple steps (bolts, nuts, washers) are replaced with a simplified pin-type locking mechanism. The locking component with clamping protrusions replaces complex fastening assemblies, reducing splicing time and operational complexity while maintaining structural integrity.

AI summary
A pin-type connection apparatus includes a first connecting seat, a second connecting seat, a connecting shaft, and a locking component, wherein a receiving hole and a locking hole on the adjacent side of the receiving hole are disposed on the second connecting seat, one end of the connecting shaft is fastened to the first connecting seat, a clamping hole is disposed at the other end of the connecting shaft, the connecting shaft can extend into the receiving hole, a first clamping protrusion is disposed in the clamping hole, a second clamping protrusion is disposed at one end of the locking component, and the locking component can pass through the locking hole and extend into the clamping hole; and when the locking component is rotated to a lockout position, the first clamping protrusion can abut against the second clamping protrusion and restrain the second clamping protrusion from exiting the clamping hole. During use of the pin-type connection apparatus provided in the present invention, the connecting shaft is pushed to extend into the receiving hole, the locking component is pushed to extend into the clamping hole, and then the locking component is rotated, so that the first clamping protrusion abuts against the second clamping protrusion, and therefore the first connecting seat can be connected to the second connecting seat. The structure is simple and easy to use, and connection efficiency is high.
