Fluid Dispensing Adhesive Strip with Selective Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive strips do not effectively allow for the selective dispensing of colored fluids for entertainment purposes, such as simulating 'bleeding' team colors, without causing skin irritation or leaving stains.
Innovation Solution
A fluid-dispensing adhesive strip with a backing layer, chambers, and an activation mechanism, such as a tear-away strip, that allows for the controlled release of non-toxic, non-staining fluids like paint or dye, which can be applied to the skin to create a colorful effect.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If adhesive strips are used to dispense colored fluids for entertainment purposes, then the ability to simulate 'bleeding' team colors is achieved, but skin irritation and staining occur
Solution Approach 1:
The adhesive strip is divided into separate functional zones: adhesive regions for attachment and distinct fluid-containing chambers for color dispensing. This segmentation allows the adhesive to be optimized for skin bonding while the fluid chambers use separate activation mechanisms, enabling controlled fluid release without continuous skin contact that causes irritation and staining.
Solution Approach 2:
A protective release strip acts as an intermediary between the adhesive and the external environment. This release strip prevents premature activation of the adhesive and controls the timing of fluid dispensing, allowing the user to apply the strip to skin and then selectively activate fluid release only when desired, minimizing unnecessary skin exposure to irritants and stains.
2Adaptability or versatility
If fluid dispensing mechanisms are added to adhesive strips, then selective color dispensing capability is achieved, but device complexity increases
Solution Approach 1:
The fluid dispensing mechanism is merged with the adhesive strip structure itself. The chambers containing colored fluids are integrated directly into the adhesive strip body, and the activation mechanism uses the same tear-away release strip concept already present in conventional adhesive strips. This merging eliminates the need for separate dispensing devices and reduces overall structural complexity while maintaining selective fluid dispensing capability.
Solution Approach 2:
The release strip serves multiple functions: it protects the adhesive during storage, enables application to skin, and acts as the activation mechanism for fluid dispensing. By making the release strip multi-functional, the invention avoids adding separate components for each function, thereby reducing device complexity while achieving selective fluid dispensing.
3Adaptability or versatility
If activation mechanisms are integrated into the adhesive strip, then selective dispensing control is achieved, but ease of operation is reduced
Solution Approach 1:
The user performs the activation action by simply tearing away the release strip, which is the same motion used in conventional adhesive strip application. The strip is designed so that the user's natural handling and application motions automatically position and activate the fluid dispensing mechanism, eliminating the need for separate activation steps and maintaining ease of operation.
Solution Approach 2:
The adhesive strip is pre-configured with chambers positioned and oriented during manufacturing so that when the release strip is torn away during normal application, the fluid channels are automatically aligned with the skin surface. This preliminary positioning ensures that the complex fluid dispensing mechanism activates correctly through a simple user action without requiring precise manual alignment.

AI summary
A fluid dispensing adhesive strip is presented. The fluid dispensing adhesive strip includes a backing layer having a first side and a second side, an adhesive that is disposed on at least a portion of the second side of the backing layer, and a packet that is disposed on the backing layer that includes a dispensable fluid and an activation mechanism that permits selective dispensing of the dispensable fluid. The packet can include multiple chambers configured to contain the same or different fluids, and channels associated with the chambers for dispensing the fluid when the activation mechanism is activated. The activation mechanism can be a tear-away strip, and can include perforations, serrations, and scoring to facilitate activation. Release strips in communication with the adhesive can releasably detach from the adhesive enabling the fluid dispensing strip to be applied and secured to an object or person.
