Napkin Dispenser Mounting Collar for Tool-Free Counter Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional in-counter napkin dispensers require precise countertop openings and the use of fasteners for installation, which can be time-consuming and damaging, and often necessitate replacing the entire countertop when changing dispensers.
Innovation Solution
A napkin dispenser with a mounting collar that fits various counter sizes and uses hand-tightening screws and twist-locks for secure installation without tools, allowing for easy adaptation to different countertop thicknesses and eliminating the need for precise openings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional in-counter napkin dispensers are installed using fasteners and precise openings, then secure attachment is achieved, but installation time increases and countertop is damaged
Solution Approach 1:
The mounting collar incorporates self-aligning features and self-tightening mechanisms that allow the dispenser to be securely attached without external tools or fasteners. The collar's design enables it to automatically position itself and secure to the countertop opening, eliminating the need for installer intervention with drills and screws.
Solution Approach 2:
The patent removes the fasteners and complex mounting hardware from the installation process. By extracting these unnecessary components and replacing them with an integrated mounting collar design, the system achieves secure attachment through the collar's inherent structural features rather than through separate fastening elements.
2Manufacturing precision
If conventional dispensers require precise countertop openings, then secure fit is achieved, but adaptability to different counters decreases
Solution Approach 1:
The mounting collar is designed with universal adaptability to accommodate various countertop opening sizes and shapes. It incorporates adjustable and flexible mounting features that allow the same collar design to fit different counter configurations, eliminating the need for precise, custom-fitted openings for each dispenser model.
Solution Approach 2:
The mounting collar utilizes parameters such as flexible material properties, adjustable dimensions, and variable engagement mechanisms that allow it to adapt to different opening sizes. By changing these physical parameters, the collar can securely mount to various countertop configurations without requiring precise pre-cut openings.
3Stability of the object's composition
If fasteners are used to secure the housing, then stable mounting is achieved, but ease of removal decreases
Solution Approach 1:
The mounting collar employs dynamic mounting mechanisms that provide stable attachment during normal operation but allow for easy release when needed. The collar's design includes reversible engagement features that maintain firm holding strength during use but can be quickly disengaged without tools, enabling easy removal for cleaning or replacement.
Solution Approach 2:
The mounting system is segmented into separate functional components within the collar, allowing the mounting function to be independently controlled. This segmentation enables the collar to maintain stable mounting through one mechanism while providing a separate, simple release mechanism for easy removal.
4Adaptability or versatility
If the entire countertop is replaced when changing dispensers, then compatibility is ensured, but loss of time and material increases
Solution Approach 1:
The mounting collar acts as an intermediary component between the dispenser and the countertop. This intermediate element provides the adaptability and compatibility needed for different dispenser models without requiring changes to the countertop itself. The collar absorbs the variability, allowing the same countertop to accommodate multiple dispenser types.
Solution Approach 2:
The mounting collar serves multiple functions: it provides secure attachment, adapts to different opening sizes, and ensures compatibility with various dispenser models. This universal design eliminates the need to replace countertop material when changing dispensers, as the collar can be adjusted or replaced independently.

AI summary
A product dispenser, such as for dispensing napkins, designed to be recessed in a countertop or wall, includes an elongated housing or chute for holding product, a faceplate assembly, and a collar for mounting the dispenser to the countertop or wall. The collar includes a locking arrangement for securing the collar in place without requiring any tools. The locking arrangement includes a thumb screw having a threaded shaft with a first end and a second end, a wing nut at the first end, and a flap at the second end. As the wing nut is rotated in a first direction, the flap is drawn upward until it engages a stop surface, such as the underside of the countertop or inside surface of a wall.
