Telescopic Actuator Dispenser with Locking Ring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dispensing packages for personal care products are not fully reusable, leading to waste and rely on non-renewable plastic materials, which consumers find environmentally unfriendly. There is a need for a compact, reusable dispenser with a replaceable cartridge that minimizes waste and is easy to refill without manipulating the cartridge.
Innovation Solution
A dispensing package comprising a reusable dispenser with a telescopic actuator and a replaceable cartridge, where the cartridge is designed for easy insertion and made from sustainable materials, and the dispenser uses a locking ring for secure attachment, allowing for efficient dispensing of personal care products without the need for additional locking mechanisms on the cartridge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a replaceable cartridge system is used to enable partial reusability, then plastic waste is reduced, but the device complexity increases due to the need for secure attachment mechanisms
Solution Approach 1:
The locking ring is integrated as part of the reusable dispenser assembly, combining the securing function with the existing dispenser structure. This merger eliminates the need for separate locking mechanisms on the cartridge, reducing overall device complexity while maintaining secure attachment and enabling partial reusability to reduce plastic waste
Solution Approach 2:
The locking ring serves multiple functions: it secures the cartridge to the dispenser, provides structural support for the telescopic actuator, and enables easy cartridge replacement. This multi-functionality reduces the need for additional specialized components, keeping the device complexity low while achieving the waste reduction goal
2Reliability
If a locking ring is used to secure the cartridge, then the attachment is secure, but the ease of operation decreases due to additional locking mechanisms
Solution Approach 1:
The locking ring is integrated into the dispenser's existing structure rather than being a separate operation step. Users interact with the same telescopic actuator mechanism for both dispensing product and securing/removing cartridges, simplifying the operation while maintaining secure attachment
Solution Approach 2:
The telescopic actuator automatically engages and disengages the locking ring during the normal dispensing operation. When the user operates the actuator to dispense product, the mechanism self-secures the cartridge; when retracting to replace cartridges, it self-releases, eliminating the need for separate locking/unlocking actions
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 solution provides a partially reusable dispensing system that reduces plastic waste, uses sustainable materials, and simplifies the refilling process, addressing consumer concerns about environmental impact while maintaining product accessibility.

AI summary
Described herein, dispensing packages for a spreadable personal care product and its respective methods for dispensing a spreadable personal care product. The dispensing package comprises a reusable dispenser, a replaceable cartridge and optionally a top cap. The reusable dispenser comprises a tubular body and a telescopic actuator. The telescopic actuator comprises a hand wheel, a leading screw, a tubular screw and an elevator. The replaceable cartridge comprises a push plate. The telescopic actuator is able to engage with the push plate of the replaceable cartridge to deliver the personal care product such that a top surface of the elevator telescopes with a bottom surface of the push plate of the replaceable cartridge. When the hand wheel is turned in a predetermined direction, the leading screw rotates and the top surface of the elevator advances upwardly, which advances the push plate upwardly and pushes the personal care product out towards an open top of the tubular body.
