Adjustable Torch Trigger for Compact or Extended Hand Actuation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld arc processing torches lack adjustability in trigger configuration, which can lead to discomfort and inefficiency during operation, as users may need to change hand positions or finger placement depending on the operation duration or type.
Innovation Solution
A trigger mechanism for arc process torches that can be adjusted between a compact and extended configuration, allowing the extended segment to either extend along or away from the base segment, accommodating different hand positions and providing greater comfort and adjustability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the trigger is designed with a fixed configuration, then the device complexity is reduced, but the adaptability to different hand positions and operation types deteriorates
Solution Approach 1:
The trigger is divided into multiple segments: a base segment that rotates relative to the handle via a pivot, and an extended segment coupled to the base segment. This segmentation allows each segment to be independently positioned, enabling the trigger to adapt to different hand positions and operation types while maintaining manageable structural complexity through modular design.
Solution Approach 2:
The trigger transitions from a static fixed configuration to a dynamic adjustable configuration. The base segment can rotate relative to the handle, and the extended segment can move relative to the base segment, allowing the trigger to be adjusted between extended and compact configurations. This dynamic capability enables adaptation to different operational requirements without significantly increasing overall device complexity.
2Ease of operation
If the trigger can be adjusted between extended and compact configurations, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The trigger mechanism is segmented into a base segment and an extended segment that can move independently relative to each other. This segmentation allows the extended segment to be positioned optimally for ease of actuation while the base segment maintains the rotational connection to the handle. The modular segmented design achieves improved ease of operation without proportionally increasing overall mechanism complexity.
3Adaptability or versatility
If the extended segment can move relative to the base segment, then the adaptability to different operation durations and types is improved, but the stability of the trigger composition deteriorates
Solution Approach 1:
The trigger employs dynamic adjustability where the extended segment can move relative to the base segment to accommodate different operation durations and types. During actual operation, once the trigger is set to a particular configuration, it maintains stability for consistent actuation. The dynamic design allows reconfiguration between operations while providing stable composition during each specific operational mode.

AI summary
A torch for an arc process operation includes a handle and a trigger coupled to the handle. The trigger includes a base segment configured to rotate relative to the handle via a pivot, as well as an extended segment coupled to the base segment. The extended segment is configured to move relative to the base segment to transition the trigger between an extended configuration and a compact configuration, the extended segment extends away from the base segment in the extended configuration, and the extended segment extends along the base segment in the compact configuration.
