Anti-Pinch Guard Structure for Nested Insulating Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional insulating apparatuses for electrical linemen often cause accidental pinching of fingers during operation, leading to potential injury and improper nesting of sections, which can result in the apparatus being dropped.
Innovation Solution
An anti-pinch device is designed to be partially disposed around the insulating apparatus, featuring a pinch prevention mechanism with a movable extension and adjustable membrane that deflects to prevent finger ingress when actuating input elements, along with a locking mechanism for secure attachment and a tool securing element to prevent tool movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional insulating apparatuses are used for electrical operations, then the apparatus can perform electrical insulation and grounding functions, but the operator's fingers may be accidentally pinched during operation
Solution Approach 1:
The patent introduces a protective barrier or intermediary structure between the operator's finger and the pinch zone of the insulating apparatus. This intermediary element prevents direct contact between the finger and the moving parts that cause pinching, thereby eliminating the harmful effect while maintaining the apparatus's electrical insulation and grounding functions
Solution Approach 2:
The patent applies preliminary anti-action by designing features that prevent finger ingress into the pinch zone before the pinching can occur. This may include protective covers, guarded access points, or design modifications that create physical barriers against finger insertion, thereby preventing the harmful effect in advance
2Ease of operation
If the insulating apparatus allows easy actuation of input elements, then operation is simplified, but finger ingress and pinching risk increases
Solution Approach 1:
The patent introduces an intermediary protective structure that mediates between the input element and the operator's finger. This intermediary allows the finger to actuate the input element while preventing ingress into the pinch zone, thereby maintaining ease of operation while eliminating the harmful effect
Solution Approach 2:
The patent segments the access path to the input element, creating separate zones for finger actuation and for protecting against pinch hazards. This segmentation allows the input element to be easily actuated while the segmented structure prevents finger ingress into dangerous areas
3Adaptability or versatility
If the insulating apparatus sections are designed for nesting, then storage and transport are improved, but improper nesting may cause the apparatus to be dropped
Solution Approach 1:
The patent applies preliminary action by providing alignment guides, positioning features, or indication mechanisms that ensure proper nesting alignment before the sections are fully assembled. This preliminary guidance prevents improper nesting that could lead to dropping, while maintaining the adaptability and nesting capability of the apparatus
Solution Approach 2:
The patent incorporates feedback mechanisms such as alignment indicators, interlocking features, or tactile cues that provide information to the operator about the correct nesting position. This feedback ensures proper alignment during the nesting process, preventing improper assembly while maintaining the nesting capability
