Keyed Soap Dispenser Bottle Interface for Container Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dispensers for personal care products often allow the incorrect or low-quality containers to be mistakenly refilled, leading to clogging or incompatibility issues, and become obsolete with changes in product packaging or formulations.
Innovation Solution
A dispenser design featuring a housing with interchangeable key members and receptacles that match specific container depressions, ensuring only compatible containers can be used and allowing easy modification for different products by rearranging key patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dispenser is designed to be generic and capable of housing many containers of similar shape and size, then the dispenser can accommodate various personal care products, but the risk of mistakenly placing the wrong container increases and pump clogging may occur
Solution Approach 1:
The patent applies asymmetry by providing each receptacle with a unique key shape that corresponds to a specific container depression pattern. The keys are asymmetric in their configuration (different positions, shapes, and orientations of depressions) so that only the matching container can be properly inserted into each receptacle, preventing incorrect container placement while maintaining the ability to accommodate multiple different container types.
Solution Approach 2:
The patent applies local quality by making each receptacle have a distinct key configuration tailored to its specific container type. Rather than using a uniform key design for all receptacles, each receptacle's key is locally optimized with specific depression patterns that match only its intended container, ensuring reliable identification and prevention of incorrect refilling.
2Reliability
If a dispenser is designed to be specific to particular containers, then incorrect container placement is prevented, but the dispenser becomes outdated when product packaging changes
Solution Approach 1:
The patent applies segmentation by dividing the dispenser into independent, interchangeable components: multiple receptacles with different key configurations can be removed and replaced individually. When product packaging changes, only the specific receptacle needing updates must be changed, not the entire dispenser system. This modular approach maintains reliability through specific key-container matching while providing adaptability through easy component replacement.
Solution Approach 2:
The patent applies dynamics by making the key configurations changeable and interchangeable. The keys can be removed from receptacles and reconfigured or replaced to match new container types. This dynamic capability allows the dispenser to adapt to packaging changes over time while maintaining the reliable one-to-one matching between keys and containers during operation.
3Ease of operation
If multiple containers are housed in one dispenser, then user convenience is improved, but the likelihood of accidentally refilling the wrong product increases
Solution Approach 1:
The patent applies asymmetry by providing each receptacle with a unique key shape that corresponds to a specific container depression pattern. The keys are asymmetric in their configuration (different positions, shapes, and orientations of depressions) so that only the matching container can be properly inserted into each receptacle, preventing incorrect container placement while maintaining the ability to accommodate multiple different container types.

AI summary
An apparatus for dispensing a personal care product includes a housing, a first panel disposed inside the housing and including a plurality of receptacles, and a first key that is sized to be interchangeably received in each of the receptacles. The apparatus further includes a container sized and shaped to be secured in a particular orientation within the housing, and having a surface that faces the panel when the container is secured in the particular orientation within the housing. A first depression is formed in the container surface to complement with specificity the first key's exterior shape and positioned to pair with the key when the container is secured in the particular orientation within the housing and the key is received in one of the receptacles.
