Wall mounted dispenser
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fluid dispensing systems lack secure mounting to walls, prevent unauthorized access, and facilitate easy refilling.
Innovation Solution
A wall-mounted dispenser with a block-and-receiver mechanism, featuring a mounting structure that locks the container in place and can be unlocked with a simple tool, ensuring secure attachment and easy removal for refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting bracket is used to secure the dispenser to a wall, then the dispenser is prevented from unauthorized removal, but the complexity of the mounting system increases
Solution Approach 1:
The mounting system is divided into separate components: a wall-mounted bracket with a receiver and a dispenser-mounted block with locking protrusions. This segmentation allows the mounting function to be independent from the dispensing function, providing security without complicating the overall device design.
Solution Approach 2:
The mounting bracket acts as an intermediary between the wall surface and the dispenser container. It provides a secure attachment point while allowing the container to be removed only through the designed locking mechanism, thus preventing unauthorized removal without requiring direct wall attachment of the entire dispenser system.
2Reliability
If a locking mechanism is implemented to prevent unauthorized access, then security is improved, but the ease of operation for refilling is reduced
Solution Approach 1:
The locking mechanism is designed to be self-operating through a simple tool insertion into a keyhole. The tool activates a cam mechanism that automatically releases the locking protrusions from the receiver, allowing the container to be removed for refilling without complex procedures or additional assistance.
Solution Approach 2:
The locking mechanism uses simple, inexpensive components such as a basic keyhole and cam-based locking protrusions. These components are easy to manufacture and maintain, and the entire locking system can be replaced if needed without affecting the core dispensing function of the device.
3Reliability
If the container is securely locked to the mounting structure, then tamper resistance is improved, but the ease of removal for refilling is worsened
Solution Approach 1:
The locking protrusions are designed to be dynamically engaged with the receiver during normal operation, providing secure attachment. When the tool is inserted and activated, the cam mechanism dynamically changes the position of the locking protrusions, disengaging them from the receiver and allowing easy container removal for refilling.

AI summary
A dispenser that is adapted for mounting on a wall surface and for dispensing a fluid has an outer container with a base portion and a cap portion. The cap portion is removably mounted on the base portion to together define an interior compartment. A dispensing mechanism extends through an aperture in the cap portion. An inner container is positioned within the interior compartment of the outer container and operably connected with the dispensing mechanism. The inner container is adapted for storing the fluid so that it may be dispensed through the dispensing mechanism. A block extends outwardly from the outer container, the block having a top block portion that extends from the cap portion, and a bottom block portion that extends from the base portion of the outer container. A mounting structure has a front surface and a back surface, wherein the back surface of the mounting structure is adapted for mounting on the wall surface. A female receiver is formed in the mounting structure, the female receiver being sized and shaped to receive the block into the female receiver.
