Electronic Label Holder Coupler for Tool-Free Detachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic label device holders require significant force and often a special lever to detach the electronic label device, making it difficult for users to easily separate the device without additional tools.
Innovation Solution
The electronic label device holder features a design with a first coupler having a top horizontal extension and pressing portion, a second coupler with a clipping gap, and a third coupler with a guide portion, allowing the electronic label device to be stably coupled and easily detached using elastic movements and pivoting mechanisms, eliminating the need for additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hook-shaped couplers are used to prevent separation, then the electronic label device is securely retained, but significant force and special tools are required to detach it
Solution Approach 1:
The coupler structure transitions from a static hook shape to a dynamic design where the second coupler can rotate about the first coupler. This rotation capability allows the coupler to adapt between a locked position (providing retention stability) and an unlocked position (enabling easy detachment), resolving the contradiction between secure retention and easy operation.
Solution Approach 2:
The coupler is divided into multiple functional segments: a first coupler for primary attachment, a second coupler for rotation and locking, and a third coupler with elastic deformation capability. This segmentation allows each part to perform its specific function - the first coupler provides structural support, the second enables controlled movement for detachment, and the third provides elastic retention - collectively resolving the contradiction between stability and ease of operation.
2Reliability
If multiple coupled protrusions and couplers are used, then stable coupling is achieved, but the structure becomes complex and requires special levers for separation
Solution Approach 1:
Multiple coupling functions are merged into a single integrated coupler assembly. The first, second, and third couplers work together as one unit, combining attachment, rotation, locking, and elastic retention functions. This merging reduces the need for separate components and special levers, simplifying the overall structure while maintaining coupling stability.
Solution Approach 2:
The coupler assembly is designed to perform multiple functions: the first coupler provides structural attachment, the second coupler enables rotation and locking/detachment, and the third coupler provides elastic retention. This multi-functionality allows a single integrated structure to replace what would otherwise require multiple separate components and special tools, reducing device complexity while maintaining reliability.
3Ease of operation
If elastic materials are used in the coupler, then easy detachment is enabled, but the structural strength may be reduced
Solution Approach 1:
The third coupler is specifically designed with elastic material properties localized at the portion that contacts the coupled protrusion. This local elasticity provides the necessary flexibility for easy detachment while the rest of the coupler structure maintains rigid construction for structural strength. This localized application of elastic quality resolves the contradiction between ease of operation and overall structural strength.

AI summary
A holder for holding an electronic label device includes a body; a first coupler including a top horizontal extension and a pressing portion extending from the top horizontal extension in a front direction at a predetermined curvature; a second coupler extending in a horizontal direction and protruding from a top of the body in a front direction, wherein the second coupler is spaced from the pressing portion to define a clipping gap therebetween; and a third coupler including: a bottom horizontal extension extending in a horizontal direction and protruding from a bottom of the body in a front direction; and a guide portion extending from the bottom horizontal extension at a predetermined angle relative to the bottom horizontal extension, such that an upper portion of the guide portion and the bottom horizontal extension define a protrusion receiving portion.
