Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for producing gloves fail to accommodate the varied shapes of human hands, resulting in a poor fit and difficulty in putting them on.
Innovation Solution
An apparatus that welds and cuts elastic films on the outer side of a user's hand, using a combination of a top and bottom member with elastic films to form a glove shape that fits individually, allowing for easy attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional methods cut two plastic films into a glove shape and thermally weld the contour, then the glove can be produced with a basic shape, but the glove will not fit an individual hand shape due to various hand shapes
Solution Approach 1:
The patent applies preliminary action by having the user place their hand into a mold cavity before the welding and cutting process. The hand shape is captured in advance, and the elastic films are then welded and cut around this pre-positioned hand, ensuring the glove conforms to the individual's hand shape while maintaining a streamlined production process.
Solution Approach 2:
The patent utilizes parameter changes by employing elastic films that can be stretched and deformed to match the contours of the user's hand. The elastic properties of the material allow it to adapt to different hand shapes and sizes, transforming a single basic pattern into a customized fit for each user.
2Adaptability or versatility
If the glove shape is improved for better fit, then the glove can accommodate hand shape variations, but the ease of attachment and detachment deteriorates
Solution Approach 1:
The patent employs flexible shells and thin films by using elastic film material that can be stretched over the hand and then contracts to fit snugly. This flexibility allows the glove to be easily put on by stretching it over the hand and removed by pulling, while still maintaining a customized fit to the hand shape.
3Manufacturing precision
If welding and cutting is performed on the outer side of the hand contour, then the glove can be produced to fit the hand shape, but the device complexity increases
Solution Approach 1:
The patent applies universality by designing a welding and cutting means that performs both welding and cutting functions in a single integrated tool. This multi-functional device welds the elastic films together to form the glove structure and simultaneously cuts the excess material, achieving precise glove shaping without requiring separate welding and cutting apparatus.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution enables the production of gloves that fit the unique shape of each hand, ensuring a secure and comfortable fit.
Implementation Method 1
welding means for welding the first elastic film and the second elastic film
Implementation Method 2
cutting means for cutting the first elastic film and the second elastic film
Implementation Method 3
Since the first elastic film and the second elastic film have elasticity, the films adhere to the hand through their elastic resilience

AI summary
The present invention provides an apparatus for producing and putting on gloves capable of producing gloves that fit an individual hand shape and also putting the glove on the hands, and a method for producing and putting on gloves. The apparatus for producing and putting on gloves comprises welding and cutting means which welds and cuts a first elastic film and a second elastic film at a position on the outer side of a contour of a user's hand in a state in which the user's hand is sandwiched between the first elastic film and the second elastic film.
