Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
It is challenging to confirm whether a wireless communication apparatus visually recognized by a worker is the correct device to execute data writing instructions, as existing methods rely on visual perception of signal transmission, which is difficult in wireless communication techniques, and installing a display device would hinder downsizing and cost reduction.
Innovation Solution
Incorporating an optical sensor that changes output states based on light presence, allowing the wireless communication apparatus to transmit different signals indicating connection requests, and only writing data to memory when the optical sensor is in a high output state, ensuring that only visually confirmed devices execute data writing instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a display device is installed to visually confirm signal transmission for data writing, then confirmation accuracy is improved, but device size and cost increase
Solution Approach 1:
The patent introduces an optical sensor as an intermediary component that detects light signals to confirm device identity. Instead of using a display device to show confirmation, the optical sensor detects the presence or absence of light (e.g., from a flashlight or indicator) to determine whether to execute data writing, thereby avoiding the need for complex display hardware while maintaining confirmation accuracy
Solution Approach 2:
The patent replaces the mechanical/visual display system with an optical detection system. The optical sensor substitutes for display devices by using light detection (optical field interaction) to provide confirmation feedback, eliminating the need for screens or visual indicators while achieving the same confirmation purpose
2Ease of operation
If visual perception methods are used to confirm signal transmission, then confirmation simplicity is improved, but reliability in wireless communication deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the optical sensor detects light signals and provides confirmation feedback to the control circuit. The control circuit uses this feedback to determine whether to execute data writing operations, creating a reliable closed-loop confirmation system that maintains simplicity while ensuring accuracy through automated light-detection feedback
3Productivity
If data writing is enabled without optical sensor confirmation, then operation speed is improved, but data writing accuracy deteriorates
Solution Approach 1:
The patent performs preliminary confirmation action by using the optical sensor to detect light signals before executing data writing operations. The control circuit checks the optical sensor state in advance to confirm device identity, ensuring accuracy is verified beforehand so that data writing can proceed quickly without compromising precision
