Cosmetic Housing Intermediate Plate Rotation and Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product housings with intermediate plates have limited internal space accessibility due to mechanical connections, making them difficult to assemble and fragile, with the plate unable to be completely removed, thus hiding some apertures and wasting space.
Innovation Solution
A housing design featuring an intermediate plate that can rotate and slide between three positions: retracted, deployed, and release, using magnetic devices for assisted opening and closing, allowing complete separation from the base for maximum space access, eliminating the need for bulky mechanical connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If mechanical connections (pins, lugs in grooves) are used to connect the intermediate plate to the base and cover, then the plate can be positioned and moved between retracted and deployed positions, but the plate cannot be completely removed from the base, hiding some apertures and limiting space utilization
Solution Approach 1:
The patent removes the mechanical connection elements (pins, lugs, grooves) that previously prevented complete plate removal. The intermediate plate is extracted from the constrained mechanical linkage system, allowing it to be completely separated from the base and fully expose all apertures when in the deployed position, thereby maximizing accessible internal space.
Solution Approach 2:
The patent divides the housing into three independent components: base, intermediate plate, and cover. By segmenting the mechanical connections and allowing the plate to be completely separated, each component can be optimized independently while maintaining functional relationships through simpler means such as magnetic attraction or friction fit.
2Ease of operation
If mechanical connections are integrated into the design of the base, cover, and intermediate plate, then the plate can be mounted and moved, but the design becomes complicated leading to expensive and fragile moulds
Solution Approach 1:
The patent replaces complex mechanical connection systems (pins, lugs, grooves requiring precision molding) with simpler alternatives such as magnetic attraction mechanisms or friction-fit designs. This substitution eliminates the need for intricate molded features, reducing mould complexity and manufacturing costs while maintaining ease of plate mounting and movement.
3Adaptability or versatility
If the intermediate plate is designed to rotate on the cover and slide relative to the base using mechanical connections, then the plate can transition between positions, but the construction becomes difficult and fragile
Solution Approach 1:
The patent replaces fragile mechanical connections (pins, lugs in grooves) with more reliable magnetic attraction mechanisms or friction-fit designs. These alternative connection methods eliminate wear points and potential failure modes associated with mechanical linkages, improving reliability while maintaining the plate's ability to transition smoothly between retracted, deployed, and release positions.
4Device complexity
If the intermediate plate hides some apertures inside the base when in the deployed position, then the mechanical connection structure is maintained, but the utilization of space in the base is very limited
Solution Approach 1:
The patent extracts the intermediate plate from the constrained mechanical linkage system, allowing it to be completely separated from the base. When the plate is in the deployed position, it no longer blocks any apertures, enabling full utilization of the base's internal space for cosmetic product storage while maintaining a simplified mechanical connection structure.

AI summary
A housing for cosmetic product includes a base receiving at least one cosmetic product and a cover mounted on the base so as to be able to rotate, and to be moved between a closed position and an open position. The housing also includes an intermediate plate receiving at least one cosmetic product and mounted on the cover so as to be able to rotate and is arranged between the base and the cover, the plate being movable between a retracted position and a deployed position. The plate passes from the retracted position thereof to the deployed position thereof by a manipulation of the cover. The intermediate plate as well is movable in rotation between the deployed position and a release position in which the plate is led to a distance from the base so as to expose and/or make accessible the entire surface area of the base.
