Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing massagers face issues with fixed sensor response patterns that fail to cater to individual user needs, leading to inconsistent user experiences due to manufacturing variations and assembly errors.
Innovation Solution
An adaptive range determination process for sensors, where user-triggered data collection determines a current maximum range value within a preset time, ensuring the sensor operates within this range to adapt to individual user needs and enhance measurement resolution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If fixed sensor response patterns are used in massagers, then manufacturing and assembly are simplified, but user experience consistency deteriorates due to individual manufacturing errors and assembly variations
Solution Approach 1:
The patent applies preliminary action by performing sensor calibration and range determination during the manufacturing process. The system pre-determines the actual maximum range value of each sensor through calibration procedures, storing this information in the device. This preliminary calibration compensates for individual manufacturing errors before the product reaches the user, ensuring consistent user experience without requiring complex assembly adjustments.
2Device complexity
If fixed sensor response patterns are used, then device complexity is reduced, but adaptability to individual user needs deteriorates
Solution Approach 1:
The patent implements parameter changes by dynamically adjusting the sensor's working range based on the determined actual maximum range value. Instead of using a fixed response pattern, the system modifies the sensor's operational parameters (maximum range value) to match each device's specific characteristics. This allows the device to adapt to individual user needs while maintaining relatively simple control logic through automated range determination.
3Quantity of substance
If sensors operate over their full actual range, then measurement coverage is maximized, but measurement precision deteriorates due to the wider operating range
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the sensor's working range based on the determined actual maximum range value. Instead of using a fixed response pattern, the system modifies the sensor's operational parameters (maximum range value) to match each device's specific characteristics. This allows the device to adapt to individual user needs while maintaining relatively simple control logic through automated range determination.
Solution Approach 2:
The patent implements local quality by tailoring the sensor's measurement range to each specific device's actual maximum range value. Rather than using a uniform wide range for all devices, the system optimizes the measurement range locally for each device based on its calibration data. This ensures that each sensor operates with optimal precision within its specific working range, improving measurement resolution where it matters most for each individual device.
