Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for a device that can detect objects within specific spaces, such as pockets in a carry bag, and communicate this information to a portable electronic device, enhancing user convenience and preventing forgotten items.
Innovation Solution
A content detection device comprising sensors and a controller, which are placed within the carry bag's pockets, use conductive elements and magnetic forces to determine if an object is present by measuring voltage changes, and transmit this information to a connected portable device via wireless communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If sensors and controllers are integrated into the carry bag pockets, then object detection capability is improved, but device complexity increases
Solution Approach 1:
The sensor and controller are integrated into the pocket structure itself, with the sensor embedded in the pocket lining and the controller housed within the pocket wall. This nesting approach allows the detection system to be incorporated into the carry bag without adding external bulk or complexity, resolving the contradiction between detection capability and device complexity.
Solution Approach 2:
The controller serves multiple functions: it detects sensor signals indicating object presence, processes this information, and communicates with portable electronic devices via wireless modules. This multi-functionality reduces the need for separate dedicated components, thereby improving detection capability while limiting the increase in overall device complexity.
2Measurement precision
If multiple sensors are deployed in pockets, then detection accuracy is improved, but manufacturing cost increases
Solution Approach 1:
The detection system is segmented into independent sensor units that can be individually placed in different pockets. Each sensor is a simple, low-cost component that detects local conditions, and multiple sensors work together to provide comprehensive detection accuracy. This segmentation allows for improved detection through multiple sensors while keeping individual component costs low and manufacturing straightforward.
3Loss of information
If wireless communication module is added, then information transmission to portable device is improved, but energy consumption increases
Solution Approach 1:
The wireless communication module operates periodically rather than continuously, transmitting data only when sensor detections indicate changes in object presence or when triggered by specific events. This periodic operation ensures that information is transmitted reliably to the portable device while significantly reducing energy consumption compared to continuous communication.
