Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing impact tools with high-power capabilities often suffer from increased weight and vibrations, leading to deformation and damage of the lens and substrate due to inadequate shock absorption, especially during drops.
Innovation Solution
The impact tool incorporates a light emitter unit isolated from vibrations using radial and axial elastic members supported by the hammer case, which reduces the transmission of vibrations and enhances shock absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Power
If the impact tool is designed with high power output, then the power and productivity are improved, but the weight increases and causes more vibrations leading to deformation and damage of the lens and substrate
Solution Approach 1:
The patent introduces a buffer as an intermediary component positioned between the hammer case and the lens/substrate assembly. This buffer absorbs and attenuates vibrations and shocks generated during high-power operation, preventing them from reaching and damaging the lens and substrate. The buffer acts as a mediator that isolates the fragile optical components from the harsh mechanical environment while allowing the high-power mechanism to operate effectively.
Solution Approach 2:
The patent implements a buffer that provides beforehand cushioning for the lens and substrate assembly. The buffer is pre-positioned and pre-compressed to ready state, capable of absorbing sudden shocks and vibrations before they can cause damage. This prior cushioning mechanism ensures that even during high-power operation or accidental drops, the lens and substrate are protected from impact forces.
2Device complexity
If the lens and substrate are directly supported by the hammer case, then the device complexity is reduced, but the vibrations during striking propagate to the substrate causing damage
Solution Approach 1:
The buffer serves as an intermediary element between the hammer case and the lens/substrate assembly. Rather than directly mounting the optical components to the hammer case, the buffer is inserted as a intermediate layer that decouples the mechanical vibrations from the fragile components. This simple intermediary solution effectively blocks vibration transmission without requiring complex isolation systems.
3Ease of manufacture
If the hammer case cover is used to absorb shock, then the ease of manufacture is improved, but for heavy high-power products the outer rib deforms under shock causing lens and substrate damage
Solution Approach 1:
The buffer acts as an internal intermediary shock absorption mechanism, positioned between the hammer case structure and the lens/substrate assembly. While the outer hammer case cover provides external shock protection, the buffer provides internal shock attenuation closer to the vulnerable components. This layered approach with the buffer as intermediary ensures that even if the outer structure deforms under heavy shock, the lens and substrate remain protected.
Solution Approach 2:
The buffer provides beforehand cushioning specifically for the lens and substrate assembly, independent of the outer hammer case cover's performance. The buffer is pre-compressed and ready to absorb shocks before they reach the optical components, ensuring protection even when the outer structure experiences deformation under heavy loads or drops.
