Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile phone holders have large volumes, are inconvenient to carry, and pose a risk of falling, which can damage the phone due to cumbersome operation and loose screw-fixing members.
Innovation Solution
A mobile phone holder with a sliding opening mechanism utilizing a first and second coupling part connected by an extension spring, allowing for easy operation and reduced volume, where the clamping space adjusts to securely hold mobile phones and thin objects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional mobile phone holder uses a screw-fixing member with elastic member to connect left and right members, then the holder can securely clamp the mobile phone, but the holder has large volume and is not easy to be carried
Solution Approach 1:
The holder is divided into two separate members (left member and right member) that can be independently held and operated. Each member contains its own clamping portion and pressing portion, allowing the device to be segmented into portable sections while maintaining clamping functionality when assembled together.
Solution Approach 2:
The left pressing portion is designed to penetrate through the right member's accommodating portion via the sliding opening, creating a nested structure where one component passes through another. This nesting reduces the overall volume when the holder is in its compact state while still enabling the full clamping range when activated.
2Reliability
If a conventional mobile phone holder uses a screw-fixing member to connect members, then the holder can be assembled, but the screw-fixing member has a risk of falling off after multiple uses
Solution Approach 1:
The traditional screw-fixing mechanical connection is replaced with a direct sliding insertion mechanism. The left pressing portion slides through the right member's accommodating portion and locking groove, creating a secure connection through geometric interlocking rather than threaded fastening, eliminating the risk of screw loosening or falling off.
Solution Approach 2:
Instead of using a fastening element (screw) to connect the members, the design inverts the approach by having one member's pressing portion directly penetrate and lock within the other member's structure. The connection is achieved through the pressing portion engaging the locking groove from the inside, reversing the traditional external fastening approach.
3Reliability
If another type of mobile phone holder uses two L-members with compression spring, then the holder can hold the mobile phone, but both hands are needed for operation which is inconvenient
Solution Approach 1:
The functions of both L-members are merged into a single integrated structure where the left member's pressing portion serves as the operating element that directly actuates the right member's clamping portion. This consolidation allows one-handed operation while maintaining the dual-clamp holding capability, as the pressing action on one side automatically triggers the clamping action on both sides.
Solution Approach 2:
The left pressing portion acts as an intermediary element that transfers the user's single-handed pressing force to the right clamping portion through the sliding mechanism. This intermediary action allows one hand to control the operation of both clamping portions, eliminating the need for two-handed operation while maintaining balanced phone holding.
4Reliability
If another type of mobile phone holder uses two L-members that need to be operated with both hands, then the holder can clamp the phone, but careless operation will cause the falling and thus damage of the mobile phone
Solution Approach 1:
The sliding mechanism provides mechanical feedback through the locking groove geometry, which naturally limits the range of motion and prevents over-pressing. As the left pressing portion slides into the locking groove, the groove's shape provides tactile and mechanical feedback that indicates when the clamping is properly engaged, preventing careless over-operation that could cause phone damage.
Solution Approach 2:
The locking groove is designed with a predetermined depth and geometry that acts as a mechanical stop, cushioning against excessive pressing force before it can reach the phone. This pre-designed limitation protects the phone from damage by preventing the user from applying too much force, even during careless operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mobile phone holder achieves reduced volume, convenient operation, and prevents phone falling, making it suitable for carrying and securely holding mobile phones and other thin devices.
Implementation Method 1
a mobile phone holder with a sliding opening, which has a first coupling part and a second coupling part... The first coupling part and the second coupling part are coupled with each other and connected to both ends of an extension spring, respectively... due to a tensile force of the extension spring, the first clamping portion and the second clamping portion are close to each other and thus the clamping space reduces, thereby the mobile phone is held

AI summary
A mobile phone holder includes: a first coupling part having a first accommodating portion, a first clamping portion and a first pressing portion; a second coupling part having a second accommodating portion, a second clamping portion, a second pressing portion, and a sliding opening; and an extension spring. The first pressing portion penetrates into the second accommodating portion and penetrates out through the sliding opening. A clamping space is formed by the first and second clamping portions. A pressing space is formed by the first and second pressing portions. Both ends of the extension spring are fixed at the first and second accommodating portions. The first and second pressing portions are pressed toward each other such that the pressing space decreases and the clamping space increases. The first and second pressing portions are released, thereby due to a tensile force, the pressing space increases and the clamping space decreases.
