Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile phone holders lack a locking mechanism, leading to potential detachment during rough terrain, and excessive clamping members complicate phone placement and removal.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple clamping members are used to secure the phone, then the reliability of phone fixation is improved, but the device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines multiple clamping members into a single integrated clamping structure that can be operated by one moving component. The clamp member integrates the functions of multiple separate clamping elements, allowing them to work together through a single actuating member, thus reducing device complexity while maintaining fixation reliability
Solution Approach 2:
The clamp member is designed to perform multiple functions: it can clamp objects of different sizes, provide both elastic retention and locked positioning, and accommodate various object shapes. This multi-functionality replaces what would otherwise require multiple specialized clamping members, simplifying the overall device structure
2Ease of operation
If elastic member alone is used for phone retention, then the ease of operation is improved, but the reliability of phone fixation deteriorates
Solution Approach 1:
The clamping system transitions from a static elastic retention mechanism to a dynamic system with two distinct states: an unlocked state where the elastic member provides flexible retention for easy phone placement, and a locked state where the forcing member engages with the actuating member to provide rigid, vibration-resistant fixation. This dynamic state change resolves the contradiction between ease of operation and fixation reliability
Solution Approach 2:
The system changes the clamping force parameter from a continuous elastic force to a discrete locked state. The forcing member, when rotated, changes the parameter of clamping stability from 'elastic retention' to 'mechanically locked', providing enhanced reliability while maintaining ease of operation through simple rotational action
3Reliability
If locking structure is added to prevent detachment, then the reliability of phone fixation is improved, but the device complexity increases
Solution Approach 1:
The locking function is merged into the existing actuating member mechanism. The forcing member integrates with the actuating member's rotational movement, so that the same rotational action that drives the clamp member also engages the locking function through the forcing member's interaction with the actuating member, avoiding the need for a separate locking mechanism
Solution Approach 2:
The forcing member and actuating member are designed to work together in a self-locking manner. When the forcing member rotates to the locked position, it automatically engages with the actuating member to prevent reverse movement, creating a self-sustaining locked state without requiring additional springs, latches, or complex locking mechanisms

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Prevents accidental detachment of objects by ensuring secure clamping, while simplifying the process of placing and removing items.
Implementation Method 1
the resilient member generates a recovering force; when the external force is removed, the resilient member drives the actuating member to reversely rotate through the recovering force

AI summary
A expandable holder rack with rotary clamping function includes a main body, an actuating member, a resilient member, a clamping member, and a forcing member. The main body has an eccentric chamber containing the actuating member. The resilient element is connected with the main body and the actuating member. The clamping member is slidably disposed on the main body and connected with the actuating member, and allowed to expand outward and retract toward the main body when the resilient member causes the actuating member to reverse. The forcing member is disposed on the main body and rotates between a first and a second position. Thus, the forcing member presses the actuating member, preventing the clamping member from sliding, entering a positioned status; alternatively, the forcing member moves away from the actuating member, allowing the clamping member to slide, entering a free status.
