Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Automatic bundling tool devices are limited to processing only one specific type of one-piece-tie due to their design optimization for a particular cable tie geometry, head part shape, and strap length, making it difficult to handle variations in foot part geometry, neck part shape, and strap dimensions.
Innovation Solution
An automatic bundling tool device with a holding unit and linear motion guiding system that uses movable gripping elements to securely hold and transport one-piece-ties of different types, allowing for flexible processing by adapting to various geometries and strap lengths through form-fit gripping contours and a drive unit that controls the motion independently of the tool cycle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the automatic bundling tool device is designed and optimized for a specific one-piece-tie type with fixed geometry and strap length, then the device achieves high reliability and precision for that specific type, but it loses the ability to process variations in foot part geometry, neck part shape, and strap dimensions
Solution Approach 1:
The holding unit employs movable gripping elements that can dynamically adjust their position and configuration to accommodate different one-piece-tie geometries. The gripping elements move along guiding structures to adapt to variations in foot part geometry, neck part shape, and strap dimensions, enabling the device to maintain reliable processing across multiple tie types rather than being fixed for a single type.
Solution Approach 2:
The holding unit is designed as a universal mechanism that can handle multiple one-piece-tie types through its adjustable gripping elements. This multi-functional design allows a single device to process various strap lengths, foot part geometries, and neck part shapes without requiring separate specialized mechanisms for each tie type, thereby achieving both reliability and adaptability.
2Device complexity
If a fixed holding mechanism is used for a specific one-piece-tie type, then the device structure remains simple and reliable, but it cannot accommodate variations in cable tie geometry and strap length
Solution Approach 1:
The holding mechanism transitions from a fixed structure to a dynamic system with movable gripping elements that can adjust their positions along guiding structures. This dynamic capability allows the mechanism to adapt to different one-piece-tie geometries while maintaining a relatively simple overall structure, avoiding the need for completely different mechanisms for each tie type.
Solution Approach 2:
The holding unit is segmented into movable gripping elements that can independently adjust their positions. This segmentation allows each element to be optimized for specific geometric constraints while the overall mechanism remains modular and manageable, balancing structural simplicity with geometric adaptability across different tie types.
3Manufacturing precision
If the transport mechanism is rigidly linked to the tool cycle with fixed timing and travel, then the process is precise and reliable for a single cable tie type, but it cannot be adjusted for different strap lengths and tie geometries
Solution Approach 1:
The transport mechanism employs dynamically adjustable timing and travel parameters that can be modified according to different strap lengths and tie geometries. The movable gripping elements and adjustable guiding structures allow the system to maintain precise transport control while adapting to various configurations, eliminating the need for rigid fixed timing linked to a single tool cycle.
Solution Approach 2:
The system enables parameter changes in transport timing and travel distances to accommodate different strap lengths. By adjusting these parameters dynamically rather than using fixed rigid linkage, the mechanism maintains manufacturing precision for each specific tie type while achieving versatility across multiple configurations.
