Innovation Solution
A bicycle sensor device with a processor element that switches between normal, service request, and data transfer modes, modifying output data to alert users of anomalies, ensuring data is transferred and uploaded to a remote server, thereby prompting users to connect for maintenance and enabling regular remote monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If battery-driven sensors with short range communication are used to reduce weight and cost, then battery weight and size are kept low, but users may forget to perform timely data transfers, making remote monitoring impossible
Solution Approach 1:
The sensor device incorporates a feedback mechanism that monitors data transfer timing and provides notifications to users when data needs to be transferred. The processor element tracks when data was last transferred and generates alerts through the transmitter element, creating a closed-loop system that ensures timely data synchronization without requiring users to remember manual transfer schedules.
Solution Approach 2:
The sensor device performs self-monitoring of its operational state and data transfer status. The processor element automatically determines when data transfer is needed and initiates communication with external devices, reducing the cognitive burden on users and ensuring reliable remote monitoring capability is maintained.
2Reliability
If internet connection is provided in the sensor to enable remote monitoring, then data can be transmitted directly to remote servers, but electrical energy consumption becomes excessively high, requiring large and heavy batteries
Solution Approach 1:
The sensor device employs periodic action by using short-range communication for data transfer at intervals rather than continuous internet connectivity. The transmitter element establishes brief communication sessions with external devices at predetermined intervals, allowing data to be transferred in periodic bursts. This approach maintains remote monitoring capability while dramatically reducing energy consumption compared to continuous internet connection.
Solution Approach 2:
The sensor device uses an external device as an intermediary between the sensor and the remote server. Data is first transferred via low-energy short-range communication to the external device, which then handles internet connectivity and server communication. This intermediary approach allows the sensor to maintain remote monitoring functionality while avoiding the high energy costs of direct internet access.
3Reliability
If sensors are used to monitor bicycle parts for wear, then maintenance can be performed timely, but users may not pay attention to or remember to perform data transfer in a timely manner
Solution Approach 1:
The sensor device implements feedback by continuously monitoring data transfer status and providing timely notifications to users. The processor element tracks when data was last transferred and generates alerts through the transmitter element when transfer is needed, ensuring users are promptly reminded to synchronize data for maintenance monitoring without significant delays.
Solution Approach 2:
The sensor device performs preliminary actions by proactively notifying users before data becomes outdated. The system anticipates when data transfer is needed and alerts users in advance, allowing them to perform data synchronization before maintenance decisions are critical, thus preventing delays in maintenance timing.

AI summary
A bicycle sensor device of the type not having Internet accessibility and comprising at least one sensor element adapted for registering data regarding the bicycle, a data storage unit adapted for storing registered data regarding the bicycle, a processor element adapted for generating an output of the sensor device, and a transmitter element adapted for transmitting by short range communication an output of the sensor device to an external device being adapted for displaying the output of the sensor device to a user. The processor element is configured to cause the transmitter element to transmit the output of the sensor device to an external device in one of a first mode, a second mode and a third mode. The first mode is a normal operation mode, the second mode is a service request mode, and the third mode is a data transfer mode.
