Innovation Solution
A method and system for configuring wristwatch straps that involves acquiring morphological data using sensors like cameras or lasers, determining optimal strap configurations based on these data, and adjusting the strap length and clasp positioning to fit the wearer's wrist and hand dimensions, considering preferences and lifestyle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional manual measurement and adjustment methods are used, then operator experience can guide configuration, but the process is imprecise and time-consuming
Solution Approach 1:
The patent replaces manual mechanical measurement with optical scanning technology. A 3D optical scanner captures the wearer's wrist and hand morphology automatically, eliminating the need for manual tape measurement and operator interpretation. This substitution of mechanical/manual processes with optical automation directly improves measurement precision while reducing configuration time.
Solution Approach 2:
The system enables self-service configuration by automatically processing the scanned morphology data to determine optimal strap length and clasp positioning. The configuration is generated autonomously based on the captured 3D data, without requiring operator intervention or experience-based judgment, thereby eliminating time loss while maintaining high precision.
2Adaptability or versatility
If multiple adjustment devices are added to achieve optimal fit, then strap configurability improves, but device complexity increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating the optimal strap configuration (length and clasp positioning) based on the wearer's 3D morphology scanned before fitting. This allows the strap to be configured correctly from the start, reducing or eliminating the need for multiple adjustment devices and complex trial-and-error adjustments, thereby maintaining adaptability while reducing device complexity.
3Reliability
If deployant clasp is used to prevent watch dropping, then security improves, but hand clearance requirement increases overall strap dimension
Solution Approach 1:
The patent uses parameter changes by optimizing the clasp positioning parameter based on the scanned hand morphology. The system calculates the precise location where the clasp should be positioned to achieve the required hand clearance while maintaining watch security. This parameter optimization allows the strap to be neither too long nor too short, resolving the contradiction between security and overall dimension.
