Stick Object Feeding Container Elastic Abutments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional stick-like object feeding containers suffer from defects such as flaws on the object surface due to rigid abutments when the object is too large, and falling issues when it's too small, due to inadequate frictional resistance, and the external appearance is compromised by visible slits for flexibility.
Innovation Solution
The container features a ring member with elastic pieces and abutments formed integrally with it, allowing for appropriate pressure contact with the object regardless of size, eliminating the need for slits in the outer sleeve and maintaining a clean appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If abutments are formed integrally with the rigid outer sleeve, then the structure is simple and strong, but the abutments cannot deform to accommodate size variations of the stick-like object
Solution Approach 1:
The abutment function is segmented from the outer sleeve by introducing a separate elastic piece (rubber component) that can deform independently. This elastic piece is pressed against the stick-like object by a spring, allowing it to adapt to size variations while maintaining the structural integrity of the rigid outer sleeve.
Solution Approach 2:
The physical state of the abutment is changed from rigid to elastic by introducing an elastic piece. This parameter change allows the abutment to deform elastically under spring pressure, accommodating variations in the size of the stick-like object while maintaining appropriate contact pressure.
2Adaptability or versatility
If U-shaped slits are formed in the outer sleeve to create elastic pieces, then flexibility is achieved, but the external appearance is spoiled by visible slits
Solution Approach 1:
The elastic piece is extracted from the outer sleeve structure and positioned as a separate component between the outer sleeve and the chuck. This extraction eliminates the need for visible slits in the outer sleeve while maintaining the flexibility needed for size adaptation.
Solution Approach 2:
An elastic piece is introduced as an intermediary component between the rigid outer sleeve and the chuck. This intermediary provides the necessary flexibility and deformation capability without compromising the external appearance of the outer sleeve, as the elastic piece is hidden within the assembly.
3Strength
If the outer sleeve is made from rigid resin or metal, then structural strength is improved, but the abutments cannot deform to prevent biting into the stick-like object
Solution Approach 1:
The abutment function is segmented from the outer sleeve by introducing a separate elastic piece that can deform independently. This elastic piece is pressed against the stick-like object by a spring, allowing it to adapt to size variations while maintaining the structural integrity of the rigid outer sleeve.
Solution Approach 2:
The elastic piece serves as a cushioning element that deforms beforehand to accommodate size variations of the stick-like object. This prior deformation prevents the rigid abutment from biting into the object surface, avoiding flaws while maintaining appropriate contact pressure.
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 ensures consistent and appropriate pressure contact with the stick-like object across varying sizes, preventing defects and maintaining the container's external appearance, while allowing easy assembly and secure operation.
Implementation Method 1

AI summary
Variations in the size of a stick-like object are accommodated, and abutments are urged to contact with the stick-like object with an appropriate pressure. A stick-like object feeding container is provided with: an outer sleeve 11 having a front spring shoe 11a formed on the internal circumference of the front portion of the outer sleeve; an inner sleeve 12 slidably inserted into the outer sleeve and having a rear spring shoe 12a provided on the outer circumference of the inner sleeve; a spring 13 abutting at its front and rear ends against the front spring shoe and the rear spring shoe, respectively, to bias the inner sleeve backward; a chuck 17 adapted to be capable of gripping, by its front end portion, the stick-like object inserted into the inner sleeve; and a chuck ring 18. A ring member 21 is interposed between the front end of the spring 13 and the front spring shoe 11a; elastic pieces 22 extending along the stick-like object are linked at the rear end to the ring member; abutments 23 are formed on the front end of the elastic pieces; and the elastic pieces 22 are configured to elastically urge the abutments to contact with the stick-like object. The inner sleeve or chuck having fitted thereon the ring member is provided with engaging pieces for preventing the ring member from moving forward movement.
