Portable Apparatus Holder With Dynamic Stopper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable apparatus holders are complex in construction, unreliable in holding the apparatus when not mounted to an object, and may detach due to varying object thicknesses, especially when the object is thin.
Innovation Solution
A simplified apparatus main body holder with a base wall, pivotable clip piece, and a stopper mechanism urged by a torsional coil spring, which ensures the stopper is engaged regardless of object thickness, providing reliable attachment and detachment without the need for additional urging members.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple coil springs are used to urge the clip piece and stopper piece, then the holding reliability is improved, but the device complexity increases
Solution Approach 1:
The patent combines the functions of multiple coil springs into a single elastic member (leaf spring). The leaf spring simultaneously urges both the clip piece and stopper piece, eliminating the need for separate coil springs and their associated mounting structures. This merging reduces part count and simplifies construction while maintaining the reliability benefits of having both urging functions active.
Solution Approach 2:
The leaf spring serves multiple functions: it acts as both the first elastic member urging the clip piece and the second elastic member urging the stopper piece. This multi-functional design replaces what would traditionally require two separate components, thereby reducing device complexity while preserving the dual urging mechanism's reliability advantages.
2Ease of operation
If the engaging piece is escaped to avoid the back face plate, then the ease of insertion is improved, but the holding reliability deteriorates when not mounted
Solution Approach 1:
The stopper piece is designed to dynamically change position based on mounting state. When not mounted, the elastic member allows the stopper piece to escape and avoid the back face plate, facilitating easy insertion. When mounted, the compression of the elastic member forces the stopper piece into engagement with the back face plate, ensuring reliable holding. This dynamic positioning resolves the contradiction between ease of insertion and holding reliability.
Solution Approach 2:
The position of the stopper piece changes based on the compression state of the elastic member. In the unmounted state, the elastic member is less compressed, allowing the stopper to escape. In the mounted state, the elastic member is compressed, changing the parameter of stopper position to ensure engagement. This parameter change enables the system to adapt to different states and resolve the reliability contradiction.
3Adaptability or versatility
If the engaging piece depth depends on mounted object thickness, then the adaptability is improved, but the holding reliability deteriorates for thin objects
Solution Approach 1:
The elastic member automatically adjusts its compression level based on the thickness of the mounted object. For thin objects, the elastic member compresses more, generating greater urging force that ensures the stopper piece engages firmly with the back face plate. This self-adjusting mechanism eliminates the need for manual adjustment and ensures reliable holding across varying thicknesses without compromising adaptability.
Solution Approach 2:
The urging force parameter of the elastic member changes in response to object thickness. When objects are thinner, the elastic member experiences greater compression, which increases the urging force applied to both the clip piece and stopper piece. This parameter change ensures that holding reliability is maintained for thin objects while preserving adaptability to different thickness ranges.

AI summary
A main body holder has a base wall with a through-hole, a holding portion, and a pivotally attached clip piece. A stopper member is movably disposed within the base wall through-hole for movement between a restricting position and a releasing position. In the restricting position, the stopper member projects from the base wall and is configured to engage and securely hold the main body of a portable apparatus on the holding portion so that the apparatus main body is only partially disposed over the base wall through-hole in a state in which the apparatus main body is fully received by the holding portion. In the releasing position, the stopper member extends into the through-hole and does not project from the base wall so that the apparatus main body is allowed to be slid relative to the holding portion. An urging member urges the clip piece into contact with the holding portion and urges the stopper member to the restricting position.
