Grinding Compact Container with Spring-Fed Holder and Cutter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing grinding compact containers require excessive force for operation, leading to discomfort and potential detachment of the dial cover, and do not provide even distribution of powder on the puff.
Innovation Solution
A grinding compact container design featuring a rotary container, a content holder that moves longitudinally but not rotationally, and an elastic member to reduce the required force and prevent dial cover detachment, using non-circular cross-sections and screw-joints to facilitate smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the user rotates the dial cover to grind the content, then the content is ground into even particles, but the user must apply excessive force causing discomfort and potential detachment
Solution Approach 1:
The patent divides the content holder into two separate components: a stationary content holder that remains fixed in the container, and a rotary content holder that rotates with the dial cover. This segmentation allows the grinding action to be performed by only the rotating portion, reducing the force required while maintaining effective grinding of the content into even particles.
Solution Approach 2:
The patent introduces a cutter as an intermediary element between the rotating content holder and the stationary content holder. The cutter, which rotates with the dial cover, performs the grinding action by contacting and cutting the solidified content into even particles, eliminating the need for the user to apply excessive force to grind the content directly.
2Productivity
If the user rotates the dial cover to move content upward, then the content is ground, but excessive rotation force causes the dial cover to become detached
Solution Approach 1:
The patent segments the content holder into stationary and rotary portions, which allows the dial cover to rotate smoothly without exerting excessive force. The stationary content holder remains anchored in the container while the rotary portion moves with the dial cover, maintaining reliable attachment even during efficient grinding operations.
Solution Approach 2:
The patent replaces the traditional mechanical screw-thread mechanism with a direct rotation system where the dial cover rotates the content holder without requiring the content holder to move vertically. This substitution eliminates the excessive rotational force that would otherwise be required to lift and grind the content, preventing dial cover detachment while maintaining grinding efficiency.
3Object-affected harmful factors
If the content is compressed into solidified form, then the content is less likely to spill, but it becomes difficult to get the powder onto the puff and distribution is uneven
Solution Approach 1:
The patent performs the grinding action as a preliminary step before the content is applied to the puff. By rotating the dial cover, the solidified content is ground into even particles in advance, transforming it from a difficult-to-apply compressed form into a finely divided powder that can be easily applied to the puff with uniform distribution.
Solution Approach 2:
The patent replaces the manual grinding approach with a mechanical rotation system where the dial cover rotates the content holder, causing the cutter to automatically grind the solidified content into fine particles. This mechanical substitution ensures even distribution of the ground powder onto the puff, eliminating the difficulty of applying compressed content while preventing spilling.
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 design reduces the force needed for grinding, provides a comfortable user experience, and prevents dial cover detachment, ensuring even distribution of the content.
Implementation Method 1
an elastic member that is arranged in a compressed state in the holding space under the content holder to push the upper surface of the content holder towards the dial cover
Implementation Method 2
using non-circular cross-sections and screw-joints to facilitate smooth operation

AI summary
A grinding compact container is disclosed, which dispenses a content in a ground form when a dial cover is rotated. A grinding compact container can include: a stationary container that defines a mounting space; a rotary container that defines a holding space and is rotatable in relation to the stationary container; a content holder that is movable along a longitudinal direction but non-rotatable in relation to the stationary container; a dial cover that has a cutter for grinding the solid content on its lower surface and is coupled to the rotary container in a non-rotatable manner relative to the rotary container; and an elastic member that is arranged in a compressed state in the holding space under the content holder to push the upper surface of the content holder towards the dial cover.
