Miniature Battery Dispenser Hook Mechanism for Adhesive Tab Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Manual handling of small products, such as miniature batteries for hearing aids, is challenging due to their size, especially for elderly users with reduced dexterity or poor vision, as existing dispensers require manual removal of adhesive tabs, which complicates the process and can lead to jamming issues.
Innovation Solution
A dispenser with a product carrier and hook mechanism that automatically removes adhesive tabs from miniature products by using a hook component to catch and remove each tab during relative movement, easing the handling burden and preventing jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual handling of small products is used, then users can directly remove and insert products, but the handling difficulty increases due to small size and reduced dexterity
Solution Approach 1:
The dispenser enables self-service operation where the mechanism automatically performs tab removal and product presentation without requiring manual manipulation. The system serves itself by using the common cover strip as both a protective element and a driving mechanism that automatically advances products and removes tabs during normal operation.
Solution Approach 2:
The common cover strip acts as an intermediary element between the user and the small products. Instead of users directly handling tiny batteries with adhesive tabs, they interact with the larger, easier-to-manipulate cover strip which in turn manipulates the products through the dispensing mechanism.
2Reliability
If individual adhesive tabs are used on each battery, then each battery can be independently protected, but the manual removal process becomes more complex and time-consuming
Solution Approach 1:
Multiple individual protective functions are merged into a single common cover strip that covers all batteries simultaneously. This consolidation allows one removal action to protect multiple products while the dispensing mechanism automatically handles the separation and removal of each tab in sequence during operation.
Solution Approach 2:
The common cover strip is pre-configured with adhesive sections positioned to cover the tabs of multiple batteries before dispensing begins. This preliminary arrangement enables the system to automatically perform tab removal operations as products are dispensed, eliminating the need for users to manually remove each tab individually at the point of use.
3Extent of automation
If a common adhesive cover strip is used to mount multiple batteries, then dispensing can be automated, but the cover strip may cause jamming by becoming trapped between moving parts
Solution Approach 1:
The potentially problematic common cover strip is extracted from the traditional dispensing mechanism path. Instead of being fed through and risked getting trapped between moving parts, the cover strip is positioned to overlie the products and is removed in a controlled manner that prevents jamming while still enabling automated dispensing functionality.
Solution Approach 2:
The system employs dynamic adjustment where the cover strip's position and the dispensing mechanism's movement are coordinated to ensure the strip is removed and advanced in sync with product dispensing. This dynamic coordination prevents the strip from becoming trapped between moving parts while maintaining automated operation.
4Productivity
If the common cover strip is periodically trimmed in length, then it can be reused for multiple dispensing cycles, but the trimming process adds complexity and potential failure points
Solution Approach 1:
The common cover strip is designed as a disposable or limited-use component that is replaced rather than repeatedly trimmed and reused. This approach eliminates the complexity of trimming mechanisms while maintaining high dispensing efficiency, as the simple replacement process is more reliable than complex trimming operations.

AI summary
Adhesive tabs having individual apertures are adhered to individual miniature products to be dispensed. The products are supported on a product carrier component having passages through which the tabs individually pass. A hook component is movable relative to the product carrier component. The hook component has a hook sized to successively enter each aperture, and to successively catch and successively remove each tab from its individual product during relative movement of the components.
