Powder Discharge Container With Rotational Stem Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powder containers for makeup require users to manually attach and detach an opening/closing member to control the discharging hole, leading to inconvenience and a risk of loss or leakage during use.
Innovation Solution
A container design where the discharging hole of the button part and the connecting hole of the stem are connected or dislocated based on rotation directions, with an opening/closing member inserted into the stem that ascends/descends according to the button part's rotation, allowing for automatic opening/closing of the movement hole, preventing leakage and eliminating the need for manual attachment/detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an opening/closing member is configured to be attached and detached from the button part, then the discharging hole can be controlled to open and close, but the user experiences inconvenience and risk of losing the opening/closing member
Solution Approach 1:
The opening/closing member is merged with the stem by insertion, forming an integrated structure. The opening/closing member is inserted into the stem's insertion hole and fixed in place, eliminating the need for separate attachment and detachment operations while maintaining the control function of the discharging hole.
Solution Approach 2:
The opening/closing member is nested within the stem structure. Specifically, the opening/closing member is inserted into the insertion hole of the stem and positioned inside the button part, creating a nested configuration where the opening/closing member is contained within the stem assembly.
2Ease of operation
If the opening/closing member is inserted into the stem inside the button part and ascends/descends with rotation, then manual attachment/detachment is eliminated, but the structure becomes more complex
Solution Approach 1:
The opening/closing member is designed to move dynamically within the stem rather than being a fixed component. It can ascend and descend along the stem's axis in response to rotational movement of the button part, transforming rotational input into linear motion that controls the discharging hole.
Solution Approach 2:
The opening/closing member automatically performs its function of opening and closing the discharging hole through the mechanical coupling with the button part rotation. The system serves itself by converting the user's rotational action directly into the opening/closing action without requiring separate control steps.
3Productivity
If the discharging hole remains open during non-use, then access is ready, but powder leakage occurs when container is shaken or dropped
Solution Approach 1:
The opening/closing member is positioned to preliminarily close the discharging hole and movement hole before any leakage can occur. The default closed position of the opening/closing member prevents powder from escaping through the discharging hole, and the sealing arrangement ensures that shaking or dropping the container will not cause leakage.
Solution Approach 2:
The opening/closing member acts as an intermediary element between the powder storage chamber and the external environment. It controls the passage of powder through the movement hole and discharging hole, mediating between the stored powder and potential leakage paths.
