Wearable Band Connection Button for Quick Spring Bar Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The disassembly and assembly of wearable electronic apparatus elements, such as watch bands, are inefficient and pose a risk of injury due to poor lever operation, leading to low efficiency and potential skin scratches.
Innovation Solution
A wearable electronic apparatus design featuring a connection structure with spring bar pins, first and second springs, a button, and a cover, which allows for quick locking and unlocking of watch bands through elastic forces and guided movements, enhancing assembly and disassembly efficiency while preventing injuries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If two levers are exposed for user operation to disassemble or assemble the watch band, then the connection structure is simple, but the operation experience is poor and disassembly/assembly efficiency is low
Solution Approach 1:
Instead of using traditional levers that require sliding motion, the patent uses a button that is pressed inward to trigger the release mechanism. The spring bar pins automatically move outward when the button is pressed, inverting the conventional operation direction and achieving one-handed operation with improved efficiency
Solution Approach 2:
The patent extracts the lever mechanism entirely and replaces it with a button mechanism combined with spring bar pins. This extraction of the problematic lever component while retaining the essential function of releasing the spring bar from the shaft hole resolves the operation experience issue
2Object-affected harmful factors
If the lever is small and raised for operation, then the connection structure is compact, but there is a risk that the lever scratches skin and clothes
Solution Approach 1:
The patent introduces a button as an intermediary component between the user and the spring bar pin mechanism. The button serves as a safe interface that transmits force to release the pins without exposing sharp or raised edges that could damage skin or clothes
Solution Approach 2:
The hazardous lever component is completely removed from the design. The patent extracts the problematic element that caused scratching risks while maintaining the functional capability through the button and spring bar pin system
3Speed
If the second springs provide strong elastic force for quick locking, then the locking speed is fast, but the button may detach from the connection part
Solution Approach 1:
The patent applies counterbalancing forces to offset the strong elastic force of the second springs. The first springs provide opposing elastic force to prevent the button from detaching, creating a force equilibrium that enables fast locking while maintaining button retention
Solution Approach 2:
The patent adjusts the elastic force parameters of the spring system by using two different springs with different force characteristics. The first and second springs work together with controlled force parameters to achieve both rapid locking and secure button retention
