Wearable Connecting Structure with Detachable Pin Catch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional connecting structures for wearable devices, such as wristwatches, require complex maintenance due to the pin catch being stored in a storage space, making repairs and replacements difficult.
Innovation Solution
A connecting structure featuring a connecting pin with a step, a pin catch that moves in a recess perpendicular to the insertion hole, a biasing member to hold the pin catch, and a holder that transitions between holding and detachable states, allowing easy maintenance by detaching the pin catch from the recess.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the pin catch is stored in a storage space within the device body, then the connecting structure maintains stability and security, but maintenance and replacement of the pin catch become difficult
Solution Approach 1:
The connecting structure is divided into separable components: the device body, the pin catch, and the connecting pin. The pin catch can be independently removed from the storage space by detaching the connecting pin, allowing maintenance without disassembling the entire device. This segmentation enables easy replacement of the pin catch while maintaining secure connection during normal operation.
Solution Approach 2:
The pin catch is extracted from the storage space through a removable connection mechanism. The connecting pin serves as an extraction tool that, when removed, allows the pin catch to be taken out from the storage space. This extraction mechanism provides easy access to the pin catch for maintenance while keeping it securely stored during use.
2Stability of the object's composition
If the pin catch is firmly held in the storage space, then the connecting structure remains stable, but disassembly for maintenance requires complex procedures
Solution Approach 1:
The connection mechanism is segmented into simple, independent elements: the pin catch holder, the connecting pin, and the storage space. This segmentation allows the structure to remain stable when assembled while enabling simple disassembly by removing just the connecting pin, avoiding complex multi-step procedures.
Solution Approach 2:
Instead of requiring complex tools or procedures to disassemble the pin catch from the storage space, the design inverts the approach: a simple connecting pin is used to hold the pin catch in place, and removing this simple pin automatically releases the pin catch. This inversion simplifies the disassembly process while maintaining firm holding during operation.
3Device complexity
If the connecting structure uses a traditional pin and hole configuration, then the structure is simple, but maintenance time and costs increase
Solution Approach 1:
The connecting structure segments the pin catch into a separately replaceable component that can be accessed by removing just the connecting pin. This segmentation reduces maintenance time by allowing the pin catch to be replaced without disassembling the entire device, while the overall structure remains simple and easy to understand.
Solution Approach 2:
The connecting structure enables self-service maintenance by allowing users to easily remove and replace the pin catch themselves. The simple pin-and-holder mechanism can be manipulated without specialized tools or knowledge, reducing maintenance time and costs while keeping the structure simple.

AI summary
A connecting structure includes a connecting pin, a pin catch, a biasing member, and a holder. The connecting pin has a first portion, a second portion thicker than the first portion, and a step therebetween and connects a connecting object and a connected object (objects) by being inserted into their insertion holes. The pin catch moves in a recess in one of the objects in moving directions that are not an extending direction of the insertion holes and has a pin engagement portion that engages the step. The biasing member biases the pin catch in one of the moving directions. The holder is on the one of the objects and transitions, in response to user operation, to a first state where the holder and the biasing member holds the pin catch or a second state where the pin catch is detachable from the recess.
