Detachable Mirror Frame for Recyclable Cosmetic Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic containers with integrated mirrors pose an environmental problem due to the use of unrecyclable materials for the mirror and attachment mechanisms, leading to waste and pollution.
Innovation Solution
A container made of post-consumer recycled plastics with a detachable mirror system, where the mirror is attached to a frame with fins that slide on parallel ridges on the lid, allowing smooth movement and easy detachment for recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mirror is permanently attached to the container using unrecyclable materials, then the mirror remains securely in place during use, but the container cannot be fully recycled and causes environmental pollution
Solution Approach 1:
The mirror assembly is segmented into a detachable frame structure that can be separated from the container. The frame includes engagement features that allow it to be attached to and detached from the container, enabling the mirror to be removed for recycling while maintaining secure attachment during use.
Solution Approach 2:
The mirror attachment system transitions from a static permanent bond to a dynamic detachable connection. The frame incorporates movable engagement features that allow the mirror assembly to be easily attached and detached from the container, changing its state from fixed to removable.
2Ease of manufacture
If the mirror is made from unrecyclable materials, then the mirror can be easily manufactured and attached, but it creates waste and cannot be recycled after use
Solution Approach 1:
The mirror is extracted from the permanent container structure and placed in a detachable frame. This allows the mirror assembly to be removed and separated from the recyclable container, enabling the container to be fully recycled while the mirror can be disposed of or replaced independently.
Solution Approach 2:
The design enables the mirror assembly to be discarded from the container after use, while the container itself can be recovered and recycled. The detachable frame system facilitates this separation, allowing the recyclable container material to be recovered without the contamination of unrecyclable mirror materials.
3Reliability
If the frame is rigidly fixed to the lid, then the mirror remains stable during use, but the attachment process creates friction and makes detachment difficult
Solution Approach 1:
The attachment system is segmented into discrete engagement features rather than a continuous rigid bond. The frame includes specific engagement elements that interface with corresponding features on the container, providing stability during use while allowing for controlled detachment.
Solution Approach 2:
The attachment system transitions from a static rigid fixation to a dynamic engagement mechanism. The frame incorporates features that allow easy attachment and detachment while maintaining stability during use, changing the state from permanently fixed to temporarily secured.

AI summary
A container includes a lid, a frame, and a mirror. The lid includes two external ridges and at least one intermediate ridge formed on a face thereof. The intermediate ridge is located between and in parallel to the external ridges. A height of the intermediate ridge is smaller than a height of the external ridges. The frame includes fins extending from a face thereof. The fins are in parallel to one another. During attachment of the frame to the lid, the fins are slidable on the intermediate and external ridges to render movement of the frame on the lid smooth like swinging of a pendulum. The mirror is attached to an opposite face of the frame.
