Audio Gift Bag Flap Mechanism Preventing Inadvertent Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gift bags for wine or distilled spirits do not prevent inadvertent activation of audio or sound players when carrying heavy items, leading to unintended sound playback.
Innovation Solution
A gift bag design featuring a flap-activated sound player mechanism, utilizing hook and loop fasteners and a sliding tongue mechanism, which ensures secure closure and prevents accidental activation, along with a handle system that cinches the bag shut, especially when carrying weighted items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the flap is held closed with simple fasteners, then the bag can be easily opened, but the audio player may be inadvertently activated when carrying heavy items
Solution Approach 1:
The patent applies preliminary anti-action by designing the T-shaped flap with shoulder portions that extend above the handle attachment points. This preliminary structural arrangement prevents the flap from being accidentally pulled open by the handle when carrying heavy items, thereby preventing inadvertent activation of the audio player before the bag is intentionally opened.
Solution Approach 2:
The patent uses dynamics by implementing a sliding tongue mechanism that moves between engaged and disengaged positions based on flap movement. When the flap is pulled open, the tongue slides to activate the audio player; when the flap is closed, the tongue returns to its initial position to deactivate the player, providing dynamic control based on the actual state of the flap.
2Strength
If the handle is tightened to secure the bag closure, then the bag remains closed under weight stress, but the flap may be pulled open and activate the sound player unintentionally
Solution Approach 1:
The T-shaped flap structure with shoulder portions extending above the handle attachment points creates a preliminary mechanical barrier. When the handle is tightened to secure the bag under load, the shoulder portions prevent the handle from pulling the flap open, thereby preventing unintentional activation of the sound player while maintaining secure closure.
3Ease of operation
If the flap is designed to fit between handle straps for retention, then the bag stays closed when carried, but the sound circuit may be accidentally activated
Solution Approach 1:
The shoulder portions of the T-shaped flap extend above the handle attachment points to create a preliminary mechanical stop. This prevents the handle straps from pulling the flap open when the bag is carried, ensuring reliable prevention of accidental activation while maintaining ease of operation through automatic retention.
Solution Approach 2:
The sliding tongue mechanism provides dynamic response to flap movement. When the flap is accidentally pulled open by handle tension, the tongue slides to activate the audio player, providing immediate feedback. When the flap returns to closed position, the tongue resets to deactivate the player, ensuring reliable operation based on actual flap state.
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
The solution effectively prevents unintentional sound activation while allowing for a secure and elegant presentation of wine or spirits, ensuring the sound player is only activated when the flap is intentionally opened, maintaining a closed position even under weight stress.
Implementation Method 1
a bag for holding an item such as a bottle containing wine or distilled spirits, and still more particularly to a bag with a flap-activated audio or sound player and handles to cinch the flap securely in a closed position
Implementation Method 2
hook and loop (for example hook and loop fasteners provided under the mark Velcro®)
Implementation Method 3
The sound circuit is typically activated by a sliding tongue mechanism. The tongue can be a strip of plastic, heavy paper or other suitable material. One end of the tongue is attached to the flap proximate a fold line dividing the flap from the back panel. The other end of the tongue is attached to a switch mechanism on the sound circuit. As the flap is raised the tongue is pulled upward, the switch is actuated to an on position and the sound circuit is activated.
Implementation Method 4
A flexible handle threaded through apertures in the front panel, side panels and back panel draws these elements inward when pulled or tightened to cinch the bag to a closed disposition. Portions of the handle are disposed to abut and press against the shoulders when the handle is tightened and the bag is in a closed disposition.
