Tape Roll Holder Spindle Hook Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tape dispensers often require disassembly or manipulation to replace tape rolls and are prone to being misplaced, leading to inconvenience and inefficiency in tape storage and use.
Innovation Solution
A tape dispenser design with a spindle that acts as a hook, allowing tape rolls to be replaced without opening or disassembling parts, and integrating a writing device holder for convenient access to a marker or pen, with a serrated cutting surface for precise tape cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full circle spindle with disassembly mechanism is used to hold tape rolls, then the tape roll can be securely held and rotated, but the replacement process becomes complex and requires opening or partially disassembling parts of the dispenser
Solution Approach 1:
The spindle is divided into two functional segments: a fixed mounting portion attached to the dispenser body and a removable rotating portion that holds the tape roll. This segmentation allows the rotating portion to be easily detached and replaced without affecting the fixed mounting structure, enabling simple tape roll replacement while maintaining secure holding during use.
Solution Approach 2:
The rotating spindle portion is extracted as a separate, removable component from the dispenser body. This extracted component can be easily removed and replaced by users without requiring disassembly of the main dispenser structure, significantly simplifying the tape roll replacement process while maintaining secure holding during operation.
2Ease of operation
If traditional tape dispensers are designed to be freely movable, then they are accessible and easy to reach, but they are frequently moved and misplaced making tape unavailable when needed
Solution Approach 1:
The dispenser is merged with a wall-mounted hook structure, combining the functions of a wall-mounted storage device and a handheld dispenser. This integration allows the dispenser to be securely固定在 a designated location on the wall, ensuring it remains accessible and available whenever needed, while still providing the functionality of a portable dispenser.
3Reliability
If a hinged cover is used to protect the spindle and tape roll, then the internal components are protected, but the replacement process requires rotating and manipulating the cover which adds complexity
Solution Approach 1:
The protective cover is extracted and replaced with a simple cap that can be easily removed and replaced. This simplified cover design eliminates complex hinged mechanisms while still providing adequate protection for the spindle and tape roll, reducing device complexity while maintaining component protection.

AI summary
A tape roll dispenser has a backplate, a spindle, a sidewall, and a cutting surface. The spindle extends outwardly from a section of the backplate that is above a lateral median line, and the tape roll engages with the topside of the spindle. The sidewall is attached to the spindle's distal end and/or the backplate and extends to an upper end that is further away from the lateral median line than the spindle's topside, and no structure extends over the spindle's topside from either the sidewall or the backplate. The cutting surface extends outwardly from the backplate at a location below the spindle's topside. A writing device holder is connected to and extends outwardly from the backplate, sidewall, or cutting surface. A tab can extend upwardly from a center section of the cutting surface to prevent the bottom section of the tape roll from swinging out away from the backplate.
