U-Shaped Tape Dispenser With Interlocking Hub Tabs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tape dispensers are unstable when used with larger diameter cores, particularly with heavy-duty packaging tape, and existing solutions either require additional material, stiffen the device, or have complex and difficult-to-use locking mechanisms that can damage the dispenser.
Innovation Solution
A U-shaped tape dispenser with flexible sidewall arm portions and inwardly facing arcuate hub portions that include a locking mechanism with complementary tabs and projections, allowing for easy installation and removal of tape rolls without requiring twisting or additional material, and providing a stable platform for dispensing heavy-duty tape.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a thick interior rib structure is included to resist squeezing, then the dispenser stability is improved, but the device complexity increases and visual appeal is reduced
Solution Approach 1:
The locking mechanism is segmented into separate hub portions with complementary tabs and projections, allowing the structure to lock without requiring thick interior ribs. This segmentation provides stability while maintaining a clean, simple exterior design suitable for marketing purposes.
2Shape
If a locking means is covered when a roll of tape is placed on the dispenser, then the visual appeal is improved, but the ease of operation deteriorates
Solution Approach 1:
The hub portions with tabs and projections act as intermediaries that provide both the locking function and the tactile feedback mechanism. Users can feel and manipulate these features through the tape roll, enabling easy operation without compromising visual appeal.
3Device complexity
If the dispenser is twisted to attach and detach the rib from the slot, then the locking mechanism is simplified, but the ease of operation deteriorates and damage risk increases
Solution Approach 1:
The complementary tabs and projections are designed to automatically engage and lock the hub portions together without requiring user twisting or complex manipulation. The structure is self-servicing, providing both simplicity and ease of operation while reducing damage risk.

AI summary
The present disclosure relates to tape dispensers that provide an easy to use locking mechanism for loading and unloading a roll of tape thereon. The dispenser includes a generally U-shaped frame with a pair of flexible sidewall arm portions that extend rearwardly in a generally side-by-side spaced apart relation. The dispenser includes inwardly facing opposed first and second hub portions that have a roll surface, a bottom surface, and an abutment surface, wherein the roll surface is configured to support the roll thereon. The frame also includes a pair of interlocking tabs disposed on the bottom surfaces hub portions. The tabs include a locking means for securing the hub portions together wherein the abutment surfaces of the first and second hubs are in direct contact.
