Accessory Component Hole Reshaping for Easier Dangling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for manufacturing accessories with dangling components require increased manufacturing time and effort due to the need for manual trimming of tapered hole surfaces, which complicates the process and prolongs production time.
Innovation Solution
A method involving the formation of a sheet-like member, piercing to create holes, reshaping the inner surfaces to swell and taper, and subsequent blanking and barreling to achieve a curved, tapered shape that reduces contact area and enhances dangling efficiency, allowing for efficient manufacturing of components that easily suspend from a body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the inner surfaces of the holes are formed into tapered shapes to reduce contact area and enhance dangling, then the dangling duration increases, but the manufacturing time and effort increase due to manual trimming
Solution Approach 1:
The invention changes the manufacturing parameters by using a punching process with a tapered punch instead of manual drilling and trimming. This allows the tapered shape to be formed automatically during the punching operation, reducing manufacturing time while achieving the same contact area reduction and dangling enhancement
Solution Approach 2:
The punching process itself performs the shaping function - the tapered punch automatically creates the tapered inner surface during the punching operation. The process serves multiple functions (cutting and shaping) in one operation, eliminating the need for separate manual trimming steps
2Ease of operation
If the inner surfaces of the holes are formed into tapered shapes to reduce contact area, then the component dangles more easily, but the device complexity increases due to additional trimming operations
Solution Approach 1:
The invention merges the punching operation with the tapered shape formation into a single process step. The tapered punch simultaneously cuts the hole and creates the tapered inner surface, combining what were previously separate operations (punching + manual trimming) into one integrated process, thereby reducing process complexity
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
This method significantly reduces manufacturing time and effort by automating the reshaping process, enabling components to be efficiently produced with enhanced dangling properties, where slight vibrations cause gemstones to twinkle effectively.
Implementation Method 1
a first reshaping step of swelling the second inner surface into the second hole by compressing a rim portion surrounding the second hole in a thickness direction of the sheet-like member
Implementation Method 2
a taper reshaping step of reshaping a part of the second inner surface into a tapered shape by pressing a tapered pin against the rim portion from a surface on one side of the sheet-like member along the thickness direction
Implementation Method 3
a shearing step of cutting the component out of the sheet-like member
Implementation Method 4
a second reshaping step of rounding a tip portion of the second inner surface having swelled by the first reshaping step, the second reshaping step including barreling the component cut out by the shearing step

AI summary
An accessory includes a body that has a first hole surrounded by a first inner surface, and a component that has a first hole surrounded by a first inner surface to be engaged with the first inner surface. A method of manufacturing the component includes: a piercing step of forming, by blanking, the second hole through a sheet-like member of which the component is formed; a first reshaping step of swelling the second inner surface into the second hole by compressing a rim portion surrounding the second hole; a shearing step of cutting the component out of the sheet-like member; and a second reshaping step of rounding a tip portion of the second inner surface having swelled by the first reshaping. The second reshaping step includes barreling the component cut out by the shearing.
