Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock-absorption structures in photographic equipment, particularly those using metal springs, suffer from diminished effectiveness over time due to fatigue and loosening, leading to compromised ability to dampen vibrations and jitters during photography.
Innovation Solution
A self-adjusting shock-absorption device featuring a movable frame that rotates along a pivot, incorporating an adjusting component and an elastic component. The adjusting component dynamically adjusts its position in response to the rotation of the movable frame, altering the length of the elastic component to maintain effective shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal spring is used for shock absorption, then initial cushioning effectiveness is achieved, but shock-absorption effectiveness diminishes over time due to fatigue and loosening
Solution Approach 1:
The patent transforms the static metal spring into a dynamic system where the elastic component's length is continuously adjusted by the adjusting component based on the movable frame's rotation angle. This dynamic adjustment allows the system to adapt to varying load conditions and prevents the elastic component from operating in a fixed state that leads to fatigue, thereby resolving the contradiction between initial effectiveness and long-term durability
Solution Approach 2:
The patent changes the physical parameters of the shock-absorption system by dynamically modifying the length of the elastic component through the adjusting component. As the movable frame rotates, the adjusting component alters the elastic component's length, changing its stiffness and load-bearing characteristics. This parameter change prevents the elastic component from remaining under constant stress, eliminating fatigue accumulation and maintaining reliable shock absorption over extended service life
2Reliability
If a fixed-length elastic component is used, then结构简单性 is maintained, but responsiveness to varying vibration frequencies is reduced
Solution Approach 1:
The patent introduces dynamics into the previously static elastic component by coupling it with the adjusting component that responds to the movable frame's rotation. This creates a dynamically adjustable system where the elastic component's length varies with the operating conditions, enhancing responsiveness to different vibration frequencies while accepting the necessary increase in structural complexity
Solution Approach 2:
The patent implements a feedback mechanism where the movable frame's rotation angle directly influences the adjusting component's position, which in turn modifies the elastic component's length. This closed-loop feedback system automatically adjusts the shock absorption characteristics in real-time based on the actual operating state, improving responsiveness without requiring external control systems

AI summary
The present disclosure pertains to the technical realm of photographic equipment, introducing a self-adjusting shock-absorption device that incorporates a movable frame and a shock-absorption mechanism. The movable frame is designed to rotate along at least one pivot. The shock-absorption mechanism comprises an adjusting component and an elastic component, where the elastic component is flexibly positioned within the movable frame, with at least one of its ends linked to the adjusting component. The end of the adjusting component, distant from the elastic component, is also movably attached to the movable frame. As the movable frame rotates along its pivot, the adjusting component dynamically shifts, resulting in a modulation of the elastic component's length.
