Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electric nail guns face challenges in extending the lifespan of resilient elements due to abrupt impact stresses, which can lead to premature wear and reduced operational efficiency.
Innovation Solution
A retrieving device with stationary and moving seats and resilient members, featuring elongated holes and extension springs, is integrated into the impact mechanism to absorb shock and distribute forces evenly, allowing for smoother movement and reduced stress on resilient components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the first resilient members are stretched to move the slide block forward, then the impact member can contact the flywheel and drive the nail forward, but the abrupt stretching causes high impact stress that reduces the lifespan of the resilient members
Solution Approach 1:
The patent introduces a retrieving device with resilient members that act as a cushioning mechanism before the main impact occurs. The retrieving resilient members are pre-compressed or pre-positioned to absorb the abrupt stretching forces, providing beforehand cushioning that protects the first resilient members from high impact stress while still enabling the nail driving function
2Ease of operation
If the swing arm is pivoted to move the impact member to contact the flywheel, then the impact mechanism can function, but the abrupt movement creates impact stress on the resilient members
Solution Approach 1:
The retrieving device acts as an intermediary mechanism between the swing arm and the impact member. The retrieving resilient members serve as a mediator that absorbs and distributes the impact stress generated by the swing arm's pivotal movement, reducing the harmful forces transmitted to the first resilient members while maintaining the operational functionality of the impact mechanism
