Inclined Strap Holder Structure for Space-Saving Wearable Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wearable electronic devices face design restrictions due to protruding strap connection structures, limiting the inner space and external appearance diversity of the housing.
Innovation Solution
A strap structure is designed with inclined holding parts that are inserted into the housing at specific angles, providing a stable coupling while minimizing external protrusions and enhancing design flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protruding lug structure is used for strap connection, then the strap can be securely connected to the housing, but the external appearance design is restricted and the inner space of the housing is reduced
Solution Approach 1:
The patent transitions from a conventional protruding lug structure to a recessed strap connecting structure. By moving the connection interface into the housing (inward direction) rather than outward, the design eliminates external protrusions while maintaining secure strap attachment. This dimensional repositioning resolves the contradiction by preserving connection reliability without compromising external appearance design freedom.
2Reliability
If a protruding lug structure is used for strap connection, then the strap can be securely connected to the housing, but the inner space of the housing is limited
Solution Approach 1:
The patent repositions the strap connection interface from an external protruding location to an internal recessed location within the housing. This dimensional change allows the connection structure to utilize the housing's internal volume efficiently, maintaining secure strap attachment while maximizing the available inner space for other components.
3Shape
If a recessed strap connecting structure with inclined holding parts is used, then the external appearance design is diversified and inner space is maximized, but the strap connection complexity increases
Solution Approach 1:
The patent employs asymmetric inclined holding parts within the recessed strap connecting structure. The first and second holding parts have different inclination angles relative to the horizontal direction, creating an asymmetric configuration that simplifies the insertion and securing process while maintaining design diversity and maximizing inner space utilization.

AI summary
A strap structure and a wearable electronic device comprising same, the strap structure being connected to one side of a housing are provided. The strap structure includes a strap body, a holder body connected to one side of the strap body, a first holder part, which protrudes toward the inside of the housing from the end on one side of the holder body, and is inserted into the housing at an angle of inclination greater than 0° and less than 90° in the inward direction of the housing, with the horizontal direction being defined as 0° and the vertical direction defined as 90° or −90° when the housing is placed with the center thereof facing upward, and a second holder part arranged at the end on the other side of the holder body and inserted into the housing at an angle of inclination less than 0° and greater than −90°.
