Handheld Holder Rack Clamp for Secure Phone Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current holders for handheld devices, such as mobile phones, do not provide a secure clamp during use on personal transport vehicles, leading to the risk of the device dropping and being damaged.
Innovation Solution
A holder with a fixed portion and a moveable portion, where the moveable portion includes third and fourth engaging portions that can engage with first and second toothed racks on the fixed portion, and an actuation mechanism to selectively actuate the moveable portion between engaged and moving configurations, providing a secure clamp.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a simple holder structure is used, then the device is easy to manufacture and operate, but the handheld device is not securely clamped and may drop during driving
Solution Approach 1:
The holder employs a moveable portion that can transition between engaged and disengaged states relative to the fixed portion. The moveable portion includes engaging portions that can engage with toothed racks on the fixed portion, creating a dynamic clamping mechanism that provides secure holding when engaged while maintaining operational simplicity through manual actuation.
Solution Approach 2:
The holder is divided into distinct functional segments: a fixed portion with toothed racks, a moveable portion with corresponding engaging portions, and an actuation mechanism. This segmentation allows each component to perform its specific function independently, achieving reliable clamping through the interaction of engaged portions with toothed racks while keeping the overall structure manageable and manufacturable.
2Reliability
If a secure clamp is implemented using engaging portions and toothed racks, then the handheld device is tightly secured, but the device complexity increases
Solution Approach 1:
The engaging portions on the moveable portion automatically engage with the toothed racks on the fixed portion through simple relative movement. The actuation mechanism facilitates this engagement without requiring complex control systems, allowing the mechanical structure itself to provide the securing function through inherent geometric compatibility between the engaging portions and toothed racks.
Solution Approach 2:
The actuation mechanism serves as an intermediary that translates simple user input into the complex motion required for the moveable portion to engage or disengage from the fixed portion. This intermediary component simplifies the user interface while managing the mechanical complexity internally, allowing secure clamping without requiring the user to directly manipulate complex mechanisms.
3Reliability
If the moveable portion is designed to move along the fixed portion with engaging portions, then the clamping security is improved, but the ease of operation is reduced
Solution Approach 1:
The actuation mechanism acts as an intermediary that simplifies the operation of moving the moveable portion along the fixed portion. By converting simple user input into the required complex motion for engagement and disengagement, the mechanism maintains ease of operation while achieving secure clamping through the interacting engaging portions and toothed racks.

AI summary
A holder for a handheld device includes a fixed portion and a moveable. The fixed portion includes a first engaging portion and a second engaging portion. The moveable portion includes a third engaging portion to engage with the first engaging portion, a fourth engaging portion to engage with the second engaging portion, and an actuation mechanism to selectively actuate the moveable portion between an engaged and a moving configuration. The engaged configuration is when the third engaging portion is moved towards and engages the first engaging portion, and the fourth engaging portion is moved towards and engages the second engaging portion. The moving configuration is when the third engaging portion is moved away from and disengages the first engaging portion and the fourth engaging portion is moved away from and disengages the second engaging portion, allowing the moveable portion to move relative to the fixed portion.
