Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing reciprocating saws face challenges in effectively clamping objects of varying sizes due to fixed clamping mouth parts, leading to cumbersome and difficult operations, especially with round or tubular objects like branches and pipes.
Innovation Solution
A clamping device with a rotatably hinge-connected clamp and clamp support, featuring snap-fit structures and elastic members, allowing for adjustable clamping angles and easy mounting/removal, ensuring stable clamping of objects during cutting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-size clamping mouth part is used, then the structure is simple, but objects of varying sizes cannot be clamped effectively
Solution Approach 1:
The clamping device employs a rotatable clamp that can change its orientation and clamping angle dynamically. The clamp rotates relative to the clamp support to adapt to objects of different sizes and shapes, transforming a static structure into a dynamic one that adjusts to varying clamping requirements.
Solution Approach 2:
The clamping device is divided into separable components: the clamp, the clamp support, and the positioning structures. This segmentation allows the clamp to rotate independently and adjust its position while maintaining connection through the hinge, enabling adaptability without requiring a completely complex integrated structure.
2Reliability
If a complex clamping component structure is used, then clamping capability is improved, but the reciprocating saw becomes clumsy and difficult to operate
Solution Approach 1:
The elastic member provides dynamic clamping force that automatically adjusts to maintain stable clamping. The clamp can rotate and adapt its position while the elastic member ensures continuous contact and stable holding, achieving reliability without requiring a bulky fixed structure.
Solution Approach 2:
The elastic member automatically provides the clamping force needed to secure the object. The system uses its own elastic deformation to generate and maintain clamping pressure, eliminating the need for additional complex mechanisms or manual adjustment during operation.
3Adaptability or versatility
If a fixed clamping structure is used, then manufacturing is simple, but the clamping mouth cannot accommodate objects outside a certain size range
Solution Approach 1:
The clamping device uses separate components (clamp, clamp support, positioning structures) that are easier to manufacture individually than a single complex fixed structure. The hinge connection and snap-fit structures are simple to produce and assemble, while providing the needed adaptability through their modular nature.
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
The clamping device provides secure and reliable clamping for objects of different sizes, simplifying operations and reducing the overall size and complexity of the reciprocating saw, enhancing user convenience and safety.
Implementation Method 1
an elastic member is also mounted between the clamp and clamp support, and the clamp can be rotated back to an initial position relative to the clamp support by means of the elastic member
Implementation Method 2
the positioning structures further comprise a first snap-fit structure formed on the clamp support, and a second snap-fit structure that can engage with the first snap-fit structure and is arranged on the housing
