Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pin wheels used for transporting terminal material strips face difficulties in accurately engaging with positioning holes when the pitch between holes is inconsistent, leading to damage to both the terminal material strip and the ratchet wheel.
Innovation Solution
A pin wheel design featuring an outer wheel with radial through-holes, an inner wheel, and movable pins supported by springs, where the pins float and engage with positioning holes, with grooves on the inner wheel to guide the pins and prevent damage, and a detection system to ensure proper alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a ratchet wheel with fixed teeth is used to transport terminal material strips, then the structure is simple and easy to manufacture, but the teeth cannot accurately engage with positioning holes when the pitch between holes is inconsistent, causing damage to the terminal material strip and the ratchet wheel
Solution Approach 1:
The pin wheel employs movable pins that can dynamically adjust their positions relative to the terminal material strip. The pins are capable of moving radially within the wheel structure, allowing them to adapt to varying pitch distances between positioning holes. This dynamic adjustment mechanism ensures reliable engagement even when the pitch is inconsistent, while maintaining a relatively simple overall structure that is easy to manufacture.
2Adaptability or versatility
If the pitch between positioning holes is inconsistent, then the terminal material strips can accommodate variations in connection, but the fixed teeth on the ratchet wheel cannot engage properly, causing damage
Solution Approach 1:
The pin wheel design allows the pins to change their positional parameters dynamically. When the pitch between positioning holes varies, the pins can move to new positions and maintain proper engagement. This parameter adjustment capability enables the system to adapt to different pitch configurations without causing damage to the terminal material strip or the wheel structure.
3Device complexity
If fixed teeth are used on the ratchet wheel, then the structure is simple, but the teeth directly abut the surface of the terminal material strip when pitch is incorrect, causing damage
Solution Approach 1:
The pin wheel replaces fixed teeth with movable pins that can dynamically adjust their positions. This dynamic structure, while slightly more complex than fixed teeth, prevents direct abutment against the terminal material strip surface by allowing the pins to move to proper engagement positions, thereby eliminating damage while maintaining reasonable device complexity.

Function Achieved in This Case
The pin wheel effectively prevents damage by ensuring pins engage correctly with positioning holes, allowing for consistent transportation of terminal material strips with varying pitch configurations, and facilitates easy assembly and replacement of components.

AI summary
A pin wheel includes an outer wheel having an inner cavity extending through the outer wheel along an axial direction and a plurality of radial through-holes communicated with the inner cavity, an inner wheel assembled in the inner cavity to rotate together with the outer wheel, a plurality of pins respectively and movably installed in the radial through-holes, and a plurality of springs making the pins floatable in the radial through-holes. A first end of each of the pins extends out of one of the radial through-holes to engage with a positioning hole of a terminal material strip. A plurality of grooves are formed on an outer peripheral surface of the inner wheel. The grooves of the inner wheel respectively correspond to a second end of each of the pins to allow the second ends of the pins to each enter one of the grooves.
