Integrated Grasping Lid for Hazardous Item Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container lids do not provide a touch-free mechanism for handling harmful or hazardous items, requiring the use of protective gloves or tongs, which are often separately purchased.
Innovation Solution
A container lid design featuring a finger entry section, thumb entry section, and grasping section that allows for the manipulation of items without direct skin contact, using materials like plastic, metal, or rubber, and incorporating mechanisms such as molded pieces or adhered tweezers to securely grasp substances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective gloves or tongs are used to handle hazardous items, then safety is improved, but device complexity and cost increase due to separate purchases
Solution Approach 1:
The patent combines the container lid with an integrated grasping mechanism that includes a finger section, thumb section, and item-contacting grasping section. This merging eliminates the need for separate protective equipment like gloves or tongs, providing safety while reducing device complexity and cost.
Solution Approach 2:
The container lid serves multiple functions: it seals the container and simultaneously provides a grasping mechanism for handling hazardous items. This multi-functionality allows the lid to replace separate protective handling tools, improving safety without increasing overall device complexity.
2Reliability
If protective gloves or tongs are used to handle hazardous items, then safety is improved, but ease of operation deteriorates due to separate purchases and additional steps
Solution Approach 1:
By integrating the grasping mechanism directly into the container lid, the patent combines sealing and handling functions into a single component. Users can safely handle hazardous items by simply using the lid itself, eliminating the need for separate protective equipment and simplifying the操作流程.
3Ease of operation
If direct skin contact is used to handle items, then ease of operation is improved, but harmful factors increase due to direct exposure to hazardous substances
Solution Approach 1:
The grasping section of the lid acts as an intermediary between the user's skin and hazardous items. Users insert their fingers and thumb into the lid's finger and thumb sections, and the grasping section contacts the hazardous item, preventing direct skin exposure while maintaining ease of operation.
Solution Approach 2:
The patent extracts the item-contacting function from the user's skin by using the lid's grasping section as the contact point. This extraction eliminates direct skin exposure to hazardous substances while keeping the handling process simple and intuitive.
4Object-affected harmful factors
If a grasping mechanism is integrated into the lid, then harmful factors are reduced by preventing direct skin contact, but device complexity increases
Solution Approach 1:
The patent merges the grasping mechanism with the container lid into a single integrated component. The lid includes a finger section, thumb section, and grasping section that work together as one unit, reducing device complexity compared to separate protective equipment while still preventing direct skin contact with hazardous items.

AI summary
A container lid with a finger entry section, a thumb entry section, a grasping section, and a mating section. The finger entry section includes a finger opening for receiving at least one finger of a hand. The thumb entry section includes a thumb opening for receiving a thumb of the hand. The grasping section is coupled to the finger entry section and the thumb entry section. The grasping section functions to grasp an item when compressed via the finger entry section and the thumb entry section and collectively prevent the finger(s) and the thumb from making direct contact with the item. The mating section is coupled to the finger entry section, the thumb entry section, and/or the grasping section and functions to mate the container lid with a container body.
