3/16 Pitch Micro Saw Chain for Stable Low-Power Cutting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing saw chains are not suitable for the lightweight and compact demands of home environments due to their large specifications and weight, with existing small-pitch chains still failing to meet these requirements.
Innovation Solution
A 3/16 in (4.76 mm) pitch micro saw chain composed of specific components with optimized dimensions and configurations, including left and right gear cutting chain sheets, a side connecting sheet, and a transmission sheet, with precise measurements for width, height, and pitch to achieve a lightweight and compact design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If existing saw chains use larger specifications and heavier weights, then cutting power and durability are improved, but portability and ease of operation deteriorate
Solution Approach 1:
The patent changes the pitch parameter from conventional larger sizes to 3/16 inch (4.76mm), and adjusts the saw line width to 4.4-5.4mm, creating a compact chain design that reduces weight while maintaining cutting effectiveness through optimized geometric parameters
2Weight of moving object
If saw chain pitch is reduced to achieve lightweight design, then portability is improved, but cutting stability and section smoothness deteriorate
Solution Approach 1:
The patent optimizes multiple parameters simultaneously: pitch (4.76mm), saw line width (4.4-5.4mm), and maximum height (8.5-9.8mm), creating a balanced configuration that maintains cutting stability despite the reduced pitch, preventing chain shake while achieving lightweight design
3Volume of moving object
If saw chain dimensions are reduced for compactness, then ease of carrying is improved, but energy consumption increases
Solution Approach 1:
The patent reduces the chain's volumetric dimensions through optimized pitch and height parameters, while the compact design actually decreases energy consumption by reducing the mass that the motor must accelerate and move, creating a positive energy efficiency outcome

AI summary
The present disclosure belongs to the technical field of gardening tools, in particular relates to a 3/16 pitch micro saw chain of a motor driven saw chain. The 3/16 pitch micro saw chain of the motor driven saw chain is composed of a left gear cutting chain sheet, a right gear cutting chain sheet, a side connecting sheet and a transmission sheet with a transmission function by riveting a chain shaft. The width A of a saw line is confirmed by an upper cutter point of the left gear cutting chain sheet/the right gear cutting chain sheet and the width A of the saw line is 4.4-5.4mm. A maximum height C is confirmed from the bottommost end of the transmission sheet with the transmission function top the highest part of the left gear cutting chain sheet/the right gear cutting chain sheet, and the maximum height C is Cl+C2=8.5-9.8mm. An average pitch is confirmed by a hole pitch T1 of the transmission sheet with the transmission function and a hole pitch T2 of the side connecting sheet and the left gear cutting chain sheet/the right gear cutting chain sheet, and T= (Tl+T2)/2=4.76mm, S=A∗C∗T=178-252mm3. The present disclosure has higher cutting efficiency for the saw sheet, light weight, easy operation, no easy shaking during use, more smooth section, stronger stability and safety, and lower power consumption.
