Rotating Strap Clip Structure for Reliable Wireless Charging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wearable electronic devices face issues with poor charging performance if the strap attached to the housing is not horizontally unfolded, and if electrical isolation is not maintained between the housing and another electronic device during charging.
Innovation Solution
A strap design that allows detachable combination with a connection pin of the housing and can be horizontally unfolded, facilitating both wearability and wireless charging by using a clip member rotatably combined with the connection pin.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the strap is combined with the housing using a spring connection pin, then the wearable electronic device can be securely attached to the user's body, but the strap cannot be horizontally unfolded for proper wireless charging
Solution Approach 1:
The connection pin is divided into two functional parts: a spring portion for secure attachment and a protrusion portion for horizontal detachment. This segmentation allows the pin to serve dual purposes - maintaining secure connection during wear while enabling easy horizontal removal for charging by applying force to the protrusion portion that extends beyond the strap assembly.
Solution Approach 2:
The protrusion portion of the connection pin acts as an intermediary element that facilitates the transition between worn state and charging state. By providing a designated horizontal interface, it mediates the detachment process without requiring separation of the entire spring mechanism, enabling users to unfold the strap for charging while maintaining the secure connection structure.
2Stability of the object's composition
If the strap is tightly connected to the housing, then wearability is improved, but the strap cannot be horizontally unfolded to maintain electrical isolation during wireless charging
Solution Approach 1:
The connection pin incorporates dynamic characteristics through its spring portion that allows vertical compression for secure attachment, while the protrusion portion enables horizontal movement for detachment. This dynamic design permits the strap to transition between a stable connected state during wear and an unfolded detached state during charging, adapting to different functional requirements.
Solution Approach 2:
The connection mechanism is segmented into a spring portion for maintaining stable connection and a protrusion portion for enabling horizontal detachment. This segmentation allows the strap assembly to maintain stability when worn while providing the adaptability to be horizontally unfolded for proper wireless charging positioning and electrical isolation.
3Strength
If a separate tool is required to separate the strap from the connection pin, then secure attachment is achieved, but charging convenience is reduced
Solution Approach 1:
The protrusion portion of the connection pin is designed to extend beyond the strap assembly, creating a self-service interface that users can directly manipulate with their fingers. This eliminates the need for separate tools by providing a built-in detachment mechanism that maintains secure attachment through the spring portion while enabling easy manual removal for charging by pushing the protrusion portion horizontally.
4Ease of operation
If the connection pin structure is simplified for easy detachment, then charging convenience is improved, but attachment strength is reduced
Solution Approach 1:
The connection pin is segmented into a spring portion that provides strong attachment through elastic force and a protrusion portion that enables easy detachment through horizontal pushing. This segmentation allows the pin to simultaneously achieve both strong attachment strength during wear and easy detachment for charging by distributing different functions to different portions of the same component.
Solution Approach 2:
The connection pin exhibits dynamic characteristics with the spring portion maintaining strong attachment through compressive force while the protrusion portion allows easy horizontal detachment. This dynamic design enables the pin to transition between a high-strength attached state and an easy-to-remove detached state, balancing attachment strength with detachment ease.
