Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a lace adjuster assembly with feedback assembly is used to measure athletic performance, then measurement precision and data accuracy are improved, but device complexity increases
Solution Approach 1:
The patent combines the lace adjuster mechanism with the feedback assembly into a single integrated unit. The feedback assembly including sensors, processors, and power sources is merged with the lace adjuster components, allowing both lace adjustment and performance measurement functions to be performed by one device rather than separate systems.
Solution Approach 2:
The lace adjuster assembly is designed to perform multiple functions: adjusting shoelace tension, measuring athletic performance metrics, capturing images, and providing feedback. This multi-functional design eliminates the need for separate devices for each function, addressing the complexity issue while maintaining measurement precision.
2Measurement precision
If dual feedback assemblies with sensors are installed on each shoe, then athletic performance analysis accuracy is improved, but weight of the shoes increases
Solution Approach 1:
The feedback system is divided into two separate assemblies, one on each shoe. Each assembly independently measures performance metrics for its respective foot, allowing for segmented data collection that improves overall measurement accuracy by capturing bilateral performance differences.
Solution Approach 2:
The patent utilizes various sensor types that detect different physical parameters (acceleration, rotation, force, position) to measure performance. By changing the measurement parameters detected by each sensor, the system achieves comprehensive performance analysis while keeping individual sensor weights minimal.
3Loss of information
If sensors and feedback assemblies are integrated into the lace adjuster, then athletic performance visualization is improved, but ease of operation decreases
Solution Approach 1:
The feedback assembly provides real-time information about athletic performance through sensors and processors. This feedback mechanism allows athletes to visualize and understand their performance metrics, compensating for the increased operational complexity by providing valuable performance information that enhances the user experience.

AI summary
A lace adjuster system for selectively adjusting shoelaces (12) of shoes (10A, 10B) of a user, including a first lace adjuster assembly (13) for use with the first shoe (10A) and a second lace adjuster assembly (13) for use with the second shoe (10B). Each lace adjuster assembly (13) includes (i) a lace adjuster (14); and (ii) a feedback assembly (15) that is mechanically coupled to the lace adjuster (14), the feedback assembly (15) selectively measuring statistical data of the user during an athletic performance, the feedback assembly (15) including a sensor assembly (216) that senses a performance characteristic of the user during the athletic performance; and a controller (360) that receives the performance characteristic and generates a statistical data point that is based at least in part on the performance characteristic. The statistical data points can be combined to generate a combined statistical data point having enhanced accuracy.
