Locking Mechanism for Floating Platform Shock Absorber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing shock-absorbing dampers in medical apparatuses are ineffective during transportation, amplifying shock loads and causing internal component damage, leading to increased manufacturing costs due to recalibration or replacement needs after delivery.
Innovation Solution
A locking mechanism comprising a first fixing component on the floating platform, a second fixing component on the base, and a third fixing component that engages to lock the platform onto the base, combined with resilient components for shock absorption, ensuring the machine's gravity center is within the locking mechanism's field, thereby restraining platform displacement and preventing vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If dampers are used to absorb shock loads during operation, then precision of detection is maintained, but shock loads during transportation are amplified causing component damage
Solution Approach 1:
The locking mechanism is activated before transportation to securely fix the machine to the base, preventing any relative movement. This preliminary action ensures that when shock loads occur during transportation, the machine cannot move relative to the base, thus avoiding component damage while allowing the dampers to function properly during operation
Solution Approach 2:
The system transitions between two states: locked state during transportation where the machine is rigidly fixed to the base, and unlocked state during operation where the machine can move relative to the base through the dampers. This dynamic switching allows the system to adapt to different operational requirements and avoid the contradiction between precision maintenance and shock absorption
2Ease of manufacture
If the machine is assembled and calibrated in advance, then manufacturing cost is reduced, but recalibration or component replacement is needed after transportation
Solution Approach 1:
The machine is assembled and calibrated once during manufacturing with the locking mechanism engaged, establishing the correct component positions. The locking mechanism then maintains these positions throughout transportation, preventing any shifts that would require recalibration. This approach preserves the initial calibration without needing post-transportation adjustments
Solution Approach 2:
The locking mechanism provides beforehand protection by securing the machine to the base before transportation begins. This prevents shock loads from causing component displacement or damage, eliminating the need for costly recalibration or component replacement after transportation
3Object-affected harmful factors
If a locking mechanism is added to prevent transportation shock, then component damage is prevented, but device complexity increases
Solution Approach 1:
The locking function is extracted as a separate, independent mechanism from the main machine structure. The locking mechanism consists of discrete components (locking arms, latches, or bolts) that can be added to the base or platform without modifying the machine itself. This modular approach prevents component damage while minimizing the increase in overall device complexity
Solution Approach 2:
The locking mechanism acts as an intermediary between the machine and the base, providing a simple connection interface. Rather than making the machine itself complex, a separate locking system is introduced that bridges the machine and base, securing the machine during transportation without requiring complex modifications to either component

Function Achieved in This Case

AI summary
A shock absorbing device includes a floating platform, a base, and at least three locking mechanisms. The floating platform is movably spaced above the base and loaded with a machine. A center of gravity of the floating platform and the machine is located within a field enclosed by the at least three locking mechanisms. Each of the at least three locking mechanisms includes a first fixing component, a second fixing component, and a third fixing component. The first fixing component is disposed on the floating platform. The second fixing component is disposed on the base and located at a position corresponding to the first fixing component. The third fixing component is disposed on the second fixing component to engage with the first fixing component, so that the floating platform can be locked onto the base, which prevents damage of internal components of the machine caused by shock loads during transportation.
