Hook Structure with Buffer Material for Shear Stress Absorption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hook mechanisms in portable electronic devices, such as laptop computers, are complex and costly due to multiple separate parts, and they are prone to breakage under shear stress as the devices are miniaturized, making assembly challenging and increasing the risk of damage during storage and handling.
Innovation Solution
A simplified hook structure incorporating a buffer material like rubber, polyurethane, or silicon rubber is integrated into the housing, which absorbs shear stress and protects the hook body from breakage by using a buffer material disposed inside the front cover with a hook body featuring horizontal plates and a pressing plate for secure fixation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate parts are used in hook mechanisms, then the hook structure can be assembled to provide retention function, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple separate components (hook body, buffer material, pressing plate) into an integrated hook structure where the buffer material is directly attached to the hook body and the pressing plate is integrated with the housing. This merging reduces the number of separate parts while maintaining the retention function, thereby reducing assembly complexity and manufacturing cost.
2Reliability
If hook mechanisms are designed with multiple components, then the retention function can be achieved, but the assembly time and labor cost increase
Solution Approach 1:
By merging the buffer material attachment directly to the hook body and integrating the pressing plate with the housing, the patent eliminates multiple assembly steps. The hook structure can be installed as a single unit or with minimal components, significantly reducing assembly time and labor cost while maintaining reliable retention function.
3Volume of moving object
If the device is miniaturized to reduce physical size, then portability is improved, but the hook structure becomes more prone to breakage under shear stress
Solution Approach 1:
The patent incorporates a buffer material (such as rubber or silicone) between the hook body and the pressing plate that acts as a cushioning element. This buffer material absorbs and distributes shear stress before it reaches the hook body, preventing breakage. This beforehand cushioning allows the device to be miniaturized while maintaining hook strength and resistance to shear stress.
Solution Approach 2:
The patent uses composite construction by combining rigid materials (for the hook body and pressing plate) with flexible buffer materials (such as rubber or silicone). This composite approach provides both structural strength and stress absorption, enabling device miniaturization without compromising hook integrity under shear stress.
4Device complexity
If the hook structure is simplified to reduce complexity, then manufacturing cost and assembly difficulty decrease, but the protection against shear stress breakage may be insufficient
Solution Approach 1:
The buffer material is integrated into the simplified hook structure as an essential component that attaches directly to the hook body. This beforehand cushioning provides protection against shear stress breakage without adding complex mechanisms, maintaining both simplicity and strength in the hook design.
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 buffer material effectively absorbs shear stress, reducing the risk of hook breakage and simplifying the assembly process, while maintaining the structural integrity and functionality of the hook mechanism, even in compact device designs.
Implementation Method 1
a buffer material (41) having a first through opening (411) disposed in a fastening groove (32) of the front cover (31)... The buffer material effectively absorbs shear stress, reducing the risk of hook breakage

AI summary
A hook structure is disclosed in the invention, which can be implemented to a housing for a monitor in a portable electronic device. The housing is comprised of a front cover and a rear cover, and the hook structure comprises at least a buffer material, hook bodies, and pressing plates. The buffer material is disposed at an inner side of the front cover and is adjacent to a through opening; each hook body has a first horizontal plate and a second horizontal plate; a lateral edge of the first horizontal plate extends into a fastening hook and penetrates through the through opening, so that the second horizontal plate is pressed tightly against the buffer material around the through opening. Each pressing plate is used to press against the second horizontal plate, so that each hook body is fixed onto the front cover inside of the housing.
