Removable Spool Holder for Tying Guns to Reduce Wire Snagging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tying guns face difficulties such as entanglement of attachment wire with plants or obstacles, risk of damage to the tie wire, increased weight due to integrated spool reserves, and limited wire length, making them unsuitable for sustained use and requiring longer arm stretches for high attachments.
Innovation Solution
A dual configuration tying gun with a removable spool holder and integrated battery, allowing for either integrated or remote spool use, reducing weight and minimizing wire tangling, and enabling the use of different types of tie wires based on configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an integrated spool is used in the tying gun, then the wire supply is secure and manageable, but the weight of the device increases significantly
Solution Approach 1:
The device is divided into two operational modes: integrated spool mode (spool holder attached to device body) and remote spool mode (spool holder removed and used separately). This segmentation allows users to choose the configuration that best suits their needs, balancing wire supply reliability against device weight.
Solution Approach 2:
The spool holder is designed to be dynamically reconfigurable - it can be attached to or removed from the device body during operation. This dynamic adjustment enables the device to adapt its weight and functionality based on working conditions, allowing sustained use without excessive weight while maintaining secure wire supply when needed.
2Weight of moving object
If a remote spool is used, then the device weight is reduced, but the tie wire may become entangled with plants or obstacles
Solution Approach 1:
The system separates the spool holder from the device body, allowing it to be used remotely or integrated. When used remotely, the reduced weight benefits are achieved; when integrated, the wire path is shortened and more controlled, reducing entanglement risk.
Solution Approach 2:
The spool holder serves multiple functions: it can be attached to the device body for secure wire management during complex tasks, or removed and used remotely for lightweight operation during simpler tasks. This multi-functionality allows the same component to address both weight concerns and entanglement risks in different operational contexts.
3Reliability
If the spool holder is permanently integrated, then the wire supply is secure, but the device becomes unsuitable for sustained use due to weight
Solution Approach 1:
The spool holder is designed with a removable attachment mechanism that allows dynamic reconfiguration during operation. Users can attach it when secure wire supply is needed and remove it when weight reduction is prioritized, enabling sustained use across different task requirements throughout the workday.
Solution Approach 2:
The spool holder can be temporarily discarded (removed from device body) when its weight is no longer needed, and recovered (reattached) when wire supply security becomes the priority. This temporary discarding and recovering enables the device to be optimized for different phases of work, supporting sustained use over long periods.
4Adaptability or versatility
If the spool holder is removable, then the device can be optimized for different working conditions, but the device complexity increases
Solution Approach 1:
The device is segmented into modular components with standardized interfaces. The spool holder, battery, and device body each have defined attachment points and locking mechanisms, allowing flexible reconfiguration without requiring complex integration systems. This modular segmentation achieves high adaptability with relatively simple structural additions.
