Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information presentation systems lack enhanced attractiveness and interactive elements, particularly in educational settings for children, where the ability to reveal hidden information using invisible codes is not fully utilized for intellectual training.
Innovation Solution
A portable electronic device with a camera module, touch panel, and memory section that identifies photographed positions on an image with embedded invisible codes, allowing for the display of special images based on position and time conditions, providing an engaging pseudo-observation experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If invisible codes are embedded in information sections to enable hidden information presentation, then information presentation capability is improved, but device complexity increases due to additional imaging and processing sections
Solution Approach 1:
The portable electronic device integrates multiple functions into a single system: the imaging section captures both visible and invisible code information, the control section processes this data to identify photographed positions, and the display section presents both original and hidden information. This multi-functional integration resolves the contradiction by making one device perform both simple display and complex hidden information detection tasks.
Solution Approach 2:
The invisible codes are embedded within the visible information sections, creating a nested structure where hidden information is contained within the apparent content. The imaging section captures the outer visible layer while simultaneously detecting the inner invisible codes, allowing the system to access multiple information layers without requiring separate physical structures.
2Measurement precision
If the imaging section captures invisible codes to identify photographed positions, then measurement precision is improved, but difficulty of detecting and measuring increases due to invisible code recognition
Solution Approach 1:
The control section serves as an intermediary that bridges the imaging section and display section. It receives raw image data containing invisible codes, processes this data to decode the hidden information and calculate photographed positions, then transmits the processed results to the display section. This intermediary processing step resolves the detection difficulty by automating the complex recognition task.
Solution Approach 2:
The system replaces manual visual inspection and physical measurement with automated optical imaging and digital processing. The imaging section uses cameras or sensors to capture invisible code patterns, and the control section uses algorithms to interpret these patterns and determine positions, substituting mechanical detection methods with electronic and computational approaches.
3Ease of operation
If special images are displayed based on position and time conditions to enhance attractiveness, then user engagement is improved, but device complexity increases due to additional control functions
Solution Approach 1:
The display section dynamically adjusts its content based on real-time conditions: it receives photographed position data from the control section and current time information, then selectively displays special images or ordinary content accordingly. This dynamic adaptation to changing conditions enhances user engagement while the control section manages the complexity through automated conditional logic.
Solution Approach 2:
The system implements a feedback loop where the imaging section captures information, the control section analyzes it to determine photographed positions and match them against stored information, and the display section presents results based on this analysis. This feedback mechanism allows the device to respond appropriately to user actions and environmental conditions, enhancing engagement while the automated feedback process manages control complexity.

AI summary
[Problem] To provide an educational toy which allows an observed action to be experienced artificially. [Solution] A toy system (900) is used by bringing a magnifying-glass type hand-held instrument (930) into contact with a page (912) of a main body portion (910) having a picture portion (914). The magnifying-glass type hand-held instrument (930) captures an image of the picture portion (914), and determines the location, within the image in said picture portion, that has been captured. From pre-stored image data of a picture image that is the same as the picture portion (914), image data for a part (a partial image) corresponding to the location being captured are then read out and are displayed on a touch panel (942). If the location being captured fulfills certain location conditions, one image element from image elements W41 to W49 is also selected as a special image and is displayed superimposed on the partial image.
