Retractable Container With External Knock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing retractable containers face issues with reduced capacity due to space occupation by piston configurations, complex assembly leading to high costs and limited usability of internal space.
Innovation Solution
A retractable container design with a knob-operated mechanism where the knock operation part is integrated externally, utilizing a body cam and guide bars to simplify structure, allowing free use of internal space and accommodating various receptor sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a piston configuration is used for forward/rearward movement, then the container can push out and retract contents, but the capacity of the contents is reduced due to space occupation by the piston
Solution Approach 1:
The knock operation configuration is extracted from the internal space of the container body and positioned on the external surface. This allows the internal space to be fully utilized for content storage while the external knock operation part handles the deployment and retraction function, thereby resolving the space conflict.
Solution Approach 2:
The knock operation part is moved from the internal dimensional space to the external surface dimension of the container body. This spatial repositioning allows the internal volume to be dedicated entirely to content capacity while the external surface accommodates the operational mechanism.
2Ease of operation
If multiple gears or parts are individually molded and combined for knock operation, then the container can deploy and retract pen lead, but the combination structure is complicated during assembly resulting in low productivity and increased unit price
Solution Approach 1:
The knock operation part is formed as a single integrated molding that combines the extension part, pressing part, and knock operation features into one component. This eliminates the need for multiple individual parts and complex assembly operations, thereby improving productivity and reducing unit price while maintaining the deploy and retract function.
3Ease of operation
If the knock operation configuration is positioned inside the container, then the container can perform knock operation, but it is difficult to utilize the internal space of the container
Solution Approach 1:
The knock operation configuration is extracted from the internal space and positioned on the external surface of the container body. This allows the internal space to be fully utilized for content storage while the external surface accommodates the operational mechanism.
Solution Approach 2:
The knock operation part is repositioned from the internal three-dimensional space to the external surface dimension of the container body, allowing complete utilization of internal volume for content while accommodating the mechanism externally.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances productivity, reduces manufacturing costs, and enables flexible use of internal space for different receptor sizes and types, improving usability and efficiency.
Implementation Method 1
a body which accommodates a receptor supported by a spring
Implementation Method 2
a body cam integrally formed with the body and including a guide bar which extends from the body to be disposed adjacent to a side of the insertion opening, and the knob is configured to have a feature in which a knock operation part is formed integrally with a protrusion member which connects an extension part and a pressing part inserted into the insertion opening of the body, thus the guide bar of the body cam moves to respond to a change in position of the knock operation part
