Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fixing devices for outdoor equipment, such as 5G Customer Premise Equipment (CPE), are prone to failure, leading to equipment falls and potential injuries due to inadequate damping mechanisms.
Innovation Solution
A damping device comprising a housing, guide roller, friction drum, and buffer shaft, where a wire is passed through the device to suspend the equipment, utilizing a buffer to generate friction and slow down the equipment's descent when it falls, thereby preventing injury and equipment damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional fixing devices (holding poles, expansion screws, sticking back adhesive) are used to fix outdoor equipment, then the equipment can be installed on outdoor foundations, but the fixing devices are prone to failure leading to equipment falls and potential injuries
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a damping device with elastic elements (springs or rubber buffers) that are pre-configured to absorb impact energy. When the fixing device fails and equipment falls, the elastic buffer compresses to absorb the impact energy, preventing the equipment from hitting the ground with full force and thereby reducing injury risk.
Solution Approach 2:
The patent converts the harmful impact energy from equipment falls into beneficial elastic potential energy storage. The damping device uses elastic buffers that compress during impact, converting kinetic energy into elastic potential energy, which is then gradually released to control the equipment's descent and reduce harmful effects.
2Object-affected harmful factors
If a damping device with friction mechanism is used to slow down equipment descent, then injury prevention is improved, but the device complexity increases
Solution Approach 1:
The patent merges the damping function with the existing fixing device structure. The damping device is integrated into the mounting bracket or fixing mechanism, combining the support function with the energy absorption function in a single unified structure, thereby reducing overall system complexity despite adding damping capabilities.
Solution Approach 2:
The damping device uses a nested structure where the elastic buffer is positioned within the fixing device housing. The friction drum and guide roller are nested within the housing, with the wire passing through them. This nested arrangement compactly packages multiple functional elements without significantly increasing external dimensions or complexity.

Function Achieved in This Case
The damping device effectively reduces the dropping speed of outdoor equipment, preventing injuries and equipment damage by generating friction between the guide roller and friction drum, and allows for easy reassembly by releasing elastic potential energy when the force is removed.
