Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging designs for cosmetics and similar products often damage the product when opening, require complex assembly, or are difficult to control for precise application, leading to user inconvenience and material waste.
Innovation Solution
A dispensing device with a lever system and hinge mechanism that allows for rotation and sliding motion without removing a cap, featuring a locking mechanism on the front or back surface to control product access, enabling one-handed use and modular design for easy refilling and recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a removable cap is used to cover the product, then the product can be accessed, but the cap removal often damages the embedded product
Solution Approach 1:
The cap and base are merged into a single integrated structure where the cap cannot be completely removed. Instead, it rotates to become coplanar with the base, allowing product access while maintaining structural integrity and preventing damage to the embedded product.
Solution Approach 2:
The cap transitions from a static covered position to a dynamic rotated position. The hinge mechanism enables the cap to rotate between covering the orifice and becoming coplanar with the base, providing controlled access without abrupt removal that could cause damage.
2Ease of operation
If a rotational mechanism with multiple components is used to rotate the base, then the product can emerge perpendicularly, but the device complexity increases requiring four or more components
Solution Approach 1:
The hinge mechanism merges the rotational function into a single component that connects the cap and base. This eliminates the need for multiple separate components (such as gears, racks, or multiple hinges) while achieving the same perpendicular product emergence effect.
Solution Approach 2:
The hinge mechanism serves multiple functions simultaneously: it acts as a rotational joint, a structural connector, and a motion guide. This multi-functionality reduces the overall component count while maintaining the ability to rotate the base and allow perpendicular product emergence.
3Ease of operation
If a rack and pinion mechanism is used to slide the product laterally, then one-handed operation is enabled, but the mechanism is difficult to control for precise product exposure
Solution Approach 1:
The cap rotation provides dynamic control over product exposure. As the cap rotates from covering to coplanar position, it gradually exposes the product, allowing the user to control the amount of exposure based on the rotation angle, achieving precision without complex control mechanisms.
Solution Approach 2:
The complex rack and pinion mechanism is extracted and replaced with a simpler rotational motion system. The hinge mechanism directly enables the cap to rotate and expose the product without requiring intermediate sliding or gear mechanisms, simplifying both control and manufacturing.
4Ease of operation
If the hinge mechanism is allowed to slide freely along the slot, then the lever system can rotate open, but the locking mechanism is compromised
Solution Approach 1:
The locking mechanism transitions from a static locked state to a dynamic unlocked state through rotation. When the lever system rotates, the locking peg automatically disengages from the locking hole, allowing free sliding and rotation. This dynamic behavior maintains reliability by locking when closed and enabling operation when open.
Solution Approach 2:
The locking peg is pre-positioned to engage with the locking hole in the closed position. This preliminary locking action ensures the mechanism remains secure until intentionally opened, at which point the rotation automatically disengages the lock, allowing controlled movement along the slot.

AI summary
The present disclosure describes a container, applicator device, or apparatus with one or more product holders that rotate open via a set of connecting hinges located on either the faces or sides, and containing a locking system located on front or back faces of the container. The device opens by rotating a lever, with an attached cover, in the direction of the face, and using the connecting hinges to lift out the product through an orifice.
