Solution Overview

Problem

Existing bowling pin positioning systems are inefficient in disentangling entangled cables, leading to unnecessary energy consumption and prolonged operation times due to the inability to accurately identify which cables are entangled.

Innovation Solution

The system employs sensors, such as photocells, to specifically identify entangled cables, and a control unit that monitors motor energy absorption to activate brakes and adjust the carriage position, minimizing operations and energy use, while also using secondary and third guides for compact design and precise pin positioning.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the positioning device lifts and releases all pins to disentangle cables, then the cables can be disentangled, but the operation time and energy consumption increase due to unnecessary operations on non-entangled cables

Engineering Contradiction:
Improvecable disentanglementVSAvoidoperation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system divides the pin array into individual controlled units, each associated with a specific cable. When cable entanglement is detected, only the brakes corresponding to affected cables are activated, and only the carriage positions corresponding to entangled cables are adjusted. This segmented approach prevents unnecessary operations on non-entangled cables, reducing overall operation time while maintaining reliable cable disentanglement.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system incorporates sensors that continuously monitor cable position and tension to detect entanglement conditions. This feedback mechanism enables the control unit to identify which specific cables are entangled and trigger targeted disentanglement operations only for those cables, avoiding unnecessary operations on all pins and reducing operation time while ensuring reliable disentanglement where needed.
