Adjustable Collar Stay With Sliding Segmented Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for an adjustable collar stay that can be easily adapted to fit various shirt sizes and styles, allowing for quick adjustment with one hand and reusability across multiple shirts.
Innovation Solution
The adjustable collar stay consists of a lower and upper member that can be assembled and disassembled, featuring a mechanism with channels and lips for sliding engagement, allowing for extension and retraction, and includes a locking mechanism for secure positioning, enabling versatile fitment across different collar types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length collar stay is used, then the structure is simple and easy to manufacture, but it cannot adapt to various shirt sizes and styles
Solution Approach 1:
The collar stay is divided into two separate members: a lower member with a channel and an upper member with a lip. The upper member can slide within the lower member's channel, allowing the collar stay to be adjusted in length by moving the upper member to different positions along the channel. This segmentation enables adaptability while maintaining relatively simple individual component structures.
Solution Approach 2:
The collar stay transitions from a fixed-length structure to a dynamic, adjustable-length structure. The upper member can move dynamically within the lower member's channel, allowing the user to extend or retract the collar stay as needed. This dynamic capability provides versatility without requiring complex mechanisms, as the movement is achieved through simple sliding engagement.
2Adaptability or versatility
If an adjustable collar stay mechanism is added, then versatility across shirt sizes is improved, but the ease of operation deteriorates due to complex adjustment procedures
Solution Approach 1:
The adjustment mechanism allows the upper member to slide freely within the lower member's channel, enabling quick and easy length adjustment. The user can simply push or pull the upper member to the desired position without requiring complex operations. This dynamic sliding mechanism maintains ease of operation while providing versatility.
Solution Approach 2:
The collar stay adjustment is designed to be user-friendly and self-service oriented. The sliding mechanism allows the user to independently adjust the length to fit different collar sizes without requiring tools or complex procedures. The simple engagement between the lip and channel enables intuitive adjustment.
3Reliability
If a secure locking mechanism is implemented, then reliability of positioning is improved, but the device complexity increases
Solution Approach 1:
The locking function is achieved through the segmented design of the lower member with a channel and the upper member with a lip. The lip engages with the channel to provide secure positioning at various lengths. This segmentation allows for reliable locking without requiring additional complex locking components, as the engagement between the two members themselves provides the securing function.
