Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both image guidance and sound image guidance are provided simultaneously, then guidance reliability is improved, but user confusion increases due to lack of coordination between the two guidance types
Solution Approach 1:
The patent combines image guidance and sound image guidance into a unified guidance system by determining output timings based on the correlation between the two guidance types. The processing circuitry coordinates the timing of image output and sound image output so that they work together synergistically, merging their effects to improve overall guidance reliability while avoiding user confusion through coordinated presentation.
Solution Approach 2:
The system dynamically adjusts the output timing of images and sound images based on real-time correlation analysis. The processing circuitry continuously determines whether to output images, sound images, or both together by evaluating their correlation, making dynamic decisions about guidance presentation to optimize effectiveness and prevent user confusion.
2Loss of information
If image guidance and sound image guidance are output at the same time without timing coordination, then information completeness is improved, but guidance effectiveness deteriorates due to user confusion
Solution Approach 1:
The system performs preliminary analysis of the correlation between image guidance and sound image guidance before determining output timings. The processing circuitry evaluates whether the guidance information is redundant or complementary in advance, and based on this preliminary assessment, decides the appropriate timing for outputting images and sound images to ensure both completeness and effectiveness.
Solution Approach 2:
The system changes the timing parameter of guidance output based on the correlation between image and sound image guidance. By adjusting when each guidance type is presented (whether simultaneously or sequentially), the system optimizes the balance between providing complete information and maintaining clear, effective guidance that avoids user confusion.

AI summary
A reproducing apparatus includes, a first sensor, processing circuitry, an audio reproducing device, and an image reproducing device. The first sensor detects a current location of a user. The processing circuitry acquires a destination, determines a direction of the destination based on the current location, generates a guidance sound image and a guidance image, and determines a first output timing which is an output timing of the guidance sound image and a second output timing which is an output timing of the guidance image. The audio reproducing device reproduces the guidance sound image at the first output timing to guide the user toward the destination. The image reproducing device reproduces the guidance image at the second output timing to guide the user toward the destination.
