Smart Bag Notification System for Mobile Phone Retrieval
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile phones stored in bags, such as handbags, often miss notifications due to silent mode or overwhelming noise, and users may forget to retrieve their phones, leading to them being left behind.
Innovation Solution
A bag with a touch-sensitive plate and controller that wirelessly communicates with the phone, providing visual and auditory notifications through a lamp and speaker, and includes a battery pack for charging, which alerts the user if the phone is not present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the mobile phone is stored in a bag, then the bag can carry the phone along with other items, but the user may miss notifications due to silent mode or overwhelming noise
Solution Approach 1:
The patent introduces an intermediary notification system consisting of a lamp and speaker mounted on the bag's exterior. This intermediary device receives signals from the mobile phone and converts them into visible and audible notifications outside the bag, allowing users to receive notifications without directly accessing the phone while eliminating the problem of missed notifications due to silent mode or noise.
Solution Approach 2:
The patent replaces the mechanical/audio-only notification system of the mobile phone with an optical and acoustic notification system mounted on the bag. The lamp provides visual notifications through light emission, while the speaker provides audible notifications, substituting the phone's internal notification mechanisms with external bag-mounted devices that are always accessible regardless of the phone's audio settings or surrounding noise levels.
2Strength
If the mobile phone is stored in a bag, then the phone is protected from damage, but the user may forget to retrieve the phone and leave it behind
Solution Approach 1:
The patent implements a feedback system where the notification lamp and speaker provide continuous feedback to the user about the phone's status and location. When the phone is inside the bag, the notification system confirms this state through visual and audible signals, creating a feedback loop that reminds users to retrieve their phone when notifications occur, thereby preventing forgotten phones while maintaining protective storage.
Solution Approach 2:
The patent uses color changes in the notification lamp to convey different states of the mobile phone. The lamp can display different colors to indicate whether the phone is present in the bag, to notify of incoming calls or messages, or to alert that the phone has been left behind, providing intuitive visual feedback that helps users remember their phone's location and status.
3Ease of operation
If a charging plug is used to charge the mobile phone in the bag, then the phone can be charged wirelessly in the bag, but the conduction of charge may be disrupted by soiled contact surfaces
Solution Approach 1:
The patent replaces the mechanical contact-based charging system with a wireless charging system. The bag incorporates a wireless charging coil that communicates with the mobile phone's wireless charging receiver, eliminating the need for physical plug insertion and contact surface cleanliness. This substitution maintains the convenience of in-bag charging while resolving the reliability issues associated with soiled contact surfaces.
4Loss of information
If a lamp is mounted on the bag to provide visual notifications, then users can see notifications outside the bag, but the bag material may need to be rigid to anchor the lamp
Solution Approach 1:
The patent applies local quality by making only the specific area where the lamp and speaker are mounted rigid, while the rest of the bag remains flexible. The rigid plate or housing provides a stable mounting surface for the notification devices, ensuring they remain anchored and functional, while the surrounding bag material maintains its soft, flexible characteristics for comfort and versatility. This localized rigidity resolves the contradiction between notification visibility and bag flexibility.
