Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for bracelets that can aesthetically appeal while being expandable to accommodate varying wrist dimensions and prevent slipping off the wrist.
Innovation Solution
A bracelet design featuring interlocking bangles with ovular bases and arm members that can translate relative to each other, allowing for adjustable length and diameter, with springs providing a biasing force to return to a contracted state for secure fit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the bracelet is made rigid to maintain shape and structure, then structural stability is improved, but ease of placement on wrist deteriorates
Solution Approach 1:
The bracelet is divided into multiple rigid bangle segments that can translate relative to one another along guide surfaces. This segmentation allows the bracelet to maintain structural integrity while enabling expansion and contraction for easy placement on the wrist.
Solution Approach 2:
The bracelet incorporates dynamic translation capability between rigid bangle segments through guide surfaces and cam mechanisms. This allows the bracelet to transition between expanded and contracted states, providing both structural stability and ease of placement.
2Reliability
If the bracelet diameter is made fixed to maintain consistent fit, then reliability of fit is improved, but adaptability to different wrist dimensions deteriorates
Solution Approach 1:
The bracelet diameter is made dynamically adjustable through the translation of bangle segments relative to one another. This allows the bracelet to adapt to different wrist dimensions while maintaining a reliable fit through the biasing mechanism that ensures consistent contact.
Solution Approach 2:
The bracelet utilizes parameter changes in the form of variable diameter through mechanical translation of segments. The biasing mechanism maintains reliable fit parameters while the translation capability adjusts the diameter parameter to match different wrist sizes.
3Ease of operation
If springs are added to provide biasing force for automatic return, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The biasing springs enable the bracelet to automatically return to its contracted state without user intervention. This self-service mechanism improves ease of operation by eliminating the need for manual compression while adding only moderate complexity through the spring integration.
4Adaptability or versatility
If multiple bangles are used to form the bracelet, then adaptability and expandability are improved, but device complexity increases
Solution Approach 1:
The bracelet is constructed from multiple bangle segments that can translate relative to one another. This segmentation provides expandability and adaptability while the standardized interface and guide surfaces keep the overall device complexity manageable.
Solution Approach 2:
The bangle segments are designed to nest or interlock with one another through guide surfaces and cam mechanisms. This nesting arrangement enables expandability while maintaining a compact structure when contracted, balancing adaptability with controlled complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The bracelet can be easily placed on the wrist by expanding and then returns to a contracted state to prevent slipping, ensuring a comfortable and secure fit.
Implementation Method 1
springs may be operatively coupled to the first and second bangles to provide a biasing force to urge the bracelet toward its resting state
