Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cream bottles face issues with cumbersome cap closure, accidental opening during carrying, and safety concerns for children, leading to material waste and potential contamination.
Innovation Solution
A double button cream bottle design featuring an inner ring with opposing buttons connected by an elastic ring, a radially convex flange, and a cover plate with an elastic piece, allowing for secure closure and easy disengagement via simultaneous button press, preventing accidental openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screw connection is used for bottle cap closure, then the connection strength is improved, but the ease of operation deteriorates due to cumbersome closing and opening
Solution Approach 1:
The bottle cap is divided into two functional parts: a screw thread portion for secure attachment to the bottle body, and a plug portion with button mechanism for easy opening/closing. This segmentation allows each part to optimize its function - the screw threads provide strong connection while the button plug mechanism provides convenient operation.
2Ease of operation
If single button plug connection is used, then the ease of operation is improved, but the reliability deteriorates due to accidental opening during carrying
Solution Approach 1:
The button mechanism uses asymmetric positioning where the two buttons are located at specific positions on the plug portion that require deliberate, coordinated action to press simultaneously. This asymmetric design makes accidental opening highly unlikely while maintaining ease of intentional opening.
3Ease of operation
If single button plug connection is used, then the ease of operation is improved, but the safety deteriorates due to child access risk
Solution Approach 1:
The dual button configuration with specific positioning creates a mechanism that requires coordinated bimanual action or deliberate intent to operate, making it inherently difficult for children to open accidentally while remaining usable by adults.
4Loss of substance
If replacement of inner bottle body is used to reduce waste, then the loss of substance is reduced, but the device complexity increases
Solution Approach 1:
The invention merges the closure mechanism and the replacement mechanism into a single integrated button system. The same dual-button mechanism that provides secure closure also enables easy removal and replacement of the inner bottle body, eliminating the need for separate complex mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design ensures secure closure and easy opening, preventing accidental openings during carrying and child access, thus minimizing waste and enhancing user safety and convenience.
Implementation Method 1
an elastic ring connecting the two buttons; when the two buttons are simultaneously pressed, the elastic ring is pressed and deformed and disengages from the recess
Implementation Method 2
the bottle body is separated from the bottle cap by the elastic force of the elastic piece

AI summary
Disclose is a double button cream bottle, which comprises a bottle body and a bottle cap for closing the bottle body, wherein an inner ring of the bottle cap is provided with an abutment ring, an upper limit of the abutment ring is provided with a button ring, and the button ring comprises two buttons disposed opposite each other and an elastic ring connecting the two buttons; an upper portion of the bottle body is convexly and radially provided with a flange, a recess is formed at a lower end of the flange, and when the bottle body is inserted into the bottle cap, the elastic ring is snapped in the recess and limits the flange between an inner end of the bottle cap and the elastic ring; an upper end of the bottle body is covered with a cover plate, the cover plate is provided with an elastic piece upwardly tilted, and when it is closed, the elastic piece is limited between the inner end of the bottle cap and the cover plate; a side wall of the bottle cap is provided with button grooves corresponding to the buttons, and when the two buttons are simultaneously pressed, the elastic ring is pressed and deformed and disengages from the recess, so that the flange disengages from the limiting of the elastic ring; and the bottle body is separated from the bottle cap by the elastic force of the elastic piece, and through the above arrangement, the bottle body and the bottle cap can disengage from and be closed to each other without accidental opening.
