Toothbrush Display Package with Force-Activated Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face challenges in determining the optimal brushing force for oral hygiene, as high forces can lead to gum irritation and tooth enamel abrasion, and existing feedback mechanisms in toothbrushes may be insufficient or unclear, making it difficult for consumers to assess the effectiveness before purchase.
Innovation Solution
A toothbrush display package with a switch mechanism that indicates when excessive force is applied, allowing consumers to test the feedback system by simulating brushing force within the package, featuring a translucent package body with flexible portions to facilitate force application and energize an indication element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a toothbrush provides feedback mechanisms to indicate excessive brushing force, then users can be alerted to prevent gum irritation and tooth enamel abrasion, but consumers cannot assess the effectiveness of the feedback before purchase
Solution Approach 1:
The patent enables preliminary testing of the feedback mechanism by incorporating a flexible portion in the package body that allows consumers to apply force to the toothbrush head before purchase. This preliminary action lets users verify the feedback system works correctly without buying the product first.
Solution Approach 2:
The flexible portion of the package body acts as an intermediary that transmits applied force from the consumer's finger through the package to the toothbrush head. This mediator enables force application and feedback verification while maintaining the protective packaging barrier.
2Productivity
If users apply high brushing force to ensure thorough cleaning, then plaque and debris removal is improved, but gum irritation and tooth enamel abrasion occur
Solution Approach 1:
The toothbrush incorporates a feedback mechanism with an indication element that activates when excessive force is applied. The flexible portion transmits force to a switch that energizes the indication element, providing real-time feedback to users to prevent harmful brushing forces while maintaining effective cleaning.
3Strength
If the package body is made rigid to protect the toothbrush during transport, then product protection is improved, but consumers cannot test the feedback mechanism before purchase
Solution Approach 1:
The package body incorporates a localized flexible portion that provides adaptability for force application, while the rest of the package maintains rigid structural integrity for protection. This local quality differentiation allows both protection and testing functionality within the same package structure.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables consumers to assess the feedback mechanism's effectiveness before purchase, helping to prevent excessive force application and ensuring proper brushing technique, thereby reducing the risk of gum irritation and tooth enamel damage.
Implementation Method 1
the package body includes an open area configured to facilitate application of a force to the head and/or neck through the package body to place the switch in the second position, wherein the package body comprises a first portion and a second portion and the open area allows the second portion to bend with respect to the first portion

AI summary
A toothbrush having a handle and a head in a display package is described. The head is attached to a neck which is attached to the handle. An indication element is between the head and the handle and is in electrical communication with a power source. A switch connects the indication element to the power source and has a first position where the indication element is not energized and a second position where the indication element is energized. An adequate force applied to the head and an at least partially translucent package body moves the switch to the second position. The package body has a first face and a second face. The first face and/or the second face have a rugose area configured to facilitate application of a force to the head and/or neck through the package body to place the switch in the second position.
