Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional strap mechanisms for removing electronic devices from cages are uncomfortable to operate, difficult to use with one hand, and prone to breaking due to spatial constraints and excessive force application.
Innovation Solution
A strap mechanism featuring a slidable first rail with a locking part and handle, and a strap that deforms to provide component forces in specific directions, allowing easy and secure removal of electronic devices from cages, with enhanced structural strength and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional handle is used to pull the electronic device out of the cage, then the device can be removed, but the handle is operated constrainedly and uncomfortably, unable to be operated by one hand
Solution Approach 1:
The invention extracts the force application function from the handle itself and transfers it to a separate strap. The strap is pulled by the user while the handle remains stationary, allowing the handle to be small and the strap to be long, thus resolving the contradiction between compact handle dimensions and ease of operation
Solution Approach 2:
The strap acts as an intermediary between the user's pulling force and the handle. Instead of directly pulling the handle, the user pulls the strap which transmits the force to the handle through the slot mechanism, enabling one-handed operation with a compact handle
2Volume of moving object
If the handle dimensions are made small due to spatial limitation, then the device fits in the cage, but the handle is operated constrainedly and pains the user when pressed excessively
Solution Approach 1:
The invention extracts the force bearing function from the handle and transfers it to the strap. The strap, being a flexible element, can be made long and strong without increasing the handle dimensions, thus resolving the contradiction between compact size and structural strength
Solution Approach 2:
The strap is made of flexible material that can deform under pull force, distributing the stress along its length rather than concentrating it at the handle. This flexible element provides both the needed strength and the ability to absorb excessive force without breaking the handle
3Productivity
If the handle is designed for direct pulling, then the device can be removed, but the handle is broken easily at the point of force application
Solution Approach 1:
The invention separates the force application function from the handle structure. The strap absorbs all the pulling force through deformation, while the handle only provides guidance through the slot. This resolves the contradiction by making the handle durable while maintaining efficient removal capability
Solution Approach 2:
The flexible strap deforms under pull force, absorbing the stress that would otherwise concentrate at the handle's force application point. This prevents handle breakage while maintaining the ability to quickly pull the device out of the cage

Function Achieved in This Case
Enables convenient and easy operation of removing electronic devices from cages, overcoming the limitations of conventional mechanisms by providing improved structural strength and reliability, allowing for one-handed use without risk of breakage.
Implementation Method 1
the strap being for contacting against the first handle part so as to provide a component force in a first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the strap is generated by being pulled in the first direction

AI summary
A strap mechanism for drawing an electronic device from a cage in a first direction is disclosed. The strap mechanism includes a first rail. The first rail includes a first locking part for connecting with a lateral surface of the electronic device and disposed inside the cage in a slidable manner, and a first handle part connected to an end of the first locking part. A first slot is formed on the first handle part. The strap mechanism further includes a strap. A first end of the elastic strap is inserted inside the first slot. The strap is for contacting against the first handle part so as to provide a component force in the first direction and in a second direction perpendicular to the first direction to the first handle part when a deformation of the elastic strap is generated by being pulled in the first direction.
