Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Hand-held band saws require external tools for adjusting the height of the supporting member, which is inconvenient and can lead to stress collapse or damage during use, affecting working efficiency.
Innovation Solution
A hand-held band saw design featuring a supporting device with a fixing member, slider, supporting member, connection assembly, and buffer member, allowing the supporting member to be adjusted in height without external tools and providing a buffer force to prevent damage from external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the supporting member uses a rigid connection structure, then the supporting member can maintain stable position, but the supporting member cannot adapt to different working conditions and may be damaged during accidental drops or collisions
Solution Approach 1:
The patent transforms the rigid supporting member into a dynamic structure by adding a buffer member (spring) that allows the supporting member to move between a first position and a second position. The buffer member enables the supporting member to adapt to different working conditions while maintaining stability through the elastic force that returns it to its original position after displacement.
2Ease of operation
If the supporting member is designed for easy adjustment, then the user can conveniently change height, but the supporting member may become unstable or require complex locking mechanisms
Solution Approach 1:
The patent implements self-service by enabling the supporting member to be adjusted directly by hand without requiring external tools. The buffer member's elastic force automatically returns the supporting member to its original position after manual displacement, providing both ease of adjustment and position stability through the self-resetting mechanism.
3Device complexity
If the supporting member uses a simple structure, then the device complexity is reduced, but the supporting member lacks protection against damage from external forces
Solution Approach 1:
The patent applies beforehand cushioning by incorporating a buffer member (spring) between the supporting member and the housing assembly. This buffer member is pre-configured to provide elastic cushioning that absorbs external forces from accidental drops or collisions, protecting the supporting member from damage while maintaining relatively simple structural addition.
4Adaptability or versatility
If the supporting member is fixed in position, then the structure is simple and stable, but the supporting member cannot be adjusted to different heights for different workpieces
Solution Approach 1:
The patent transforms the fixed supporting member into a dynamic, adjustable structure by connecting it to a slider that can be displaced along the housing assembly. The buffer member enables the supporting member to return to its original position after adjustment, providing height adaptability while maintaining relatively simple structure through the use of basic mechanical components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient height adjustment of the supporting member and prevents damage from accidental drops or collisions, improving user experience and operational efficiency.
Implementation Method 1
the buffer member is capable of generating a buffer force, so as to enable the supporting member to return to an original position from the third position

AI summary
A hand-held band saw includes a band saw body and an supporting device. The supporting device includes a fixing member, a slider, a supporting member, and a connection assembly. The fixing member is fixedly connected to the band saw body, the slider is slidably connected to the fixing member, the supporting member supports a workpiece and is connected to the slider, and the connection assembly connectes the slider and the supporting member. When the slider moves, the connection assembly is capable of enabling the supporting member to move along with the slider. The connection assembly comprises a buffer member mounted between the slider and the supporting member.
