Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing screw and bench vices with single clamping gaps limit alternative fastening directions, leading to ergonomic issues, unreliable fastening, and increased risk of workpiece movement during processing, especially when working vertically or with irregularly shaped pieces.
Innovation Solution
A vice with two clamping gaps, one linear and one curvilinear, adjustable in direction and angle, allowing for versatile fastening options by using a linear actuator and rotatable threaded rod, enabling secure clamping from different angles and orientations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a single clamping gap is used in traditional vices, then the structure is simple, but the versatility of fastening directions is limited
Solution Approach 1:
The vice is divided into two independent clamping gap systems: a first clamping gap between the first jaw and second jaw, and a second clamping gap between the third jaw and fourth jaw. This segmentation allows each clamping gap to operate independently and provide different fastening directions, thereby increasing versatility without requiring a completely new vice design.
Solution Approach 2:
The invention adds a vertical dimension to the traditional horizontal clamping gap by introducing a second clamping gap that opens in the vertical direction. This dimensional expansion enables workpieces to be fastened from multiple directions (horizontally and vertically), solving the limitation of single-direction fastening in traditional vices.
2Reliability
If clamping from the lateral direction is used, then the vice structure is simple, but the workpiece stability is poor
Solution Approach 1:
The clamping function is segmented into two independent systems: lateral clamping (first clamping gap) and vertical clamping (second clamping gap). This segmentation allows the vertical clamping gap to provide additional stability support, preventing workpiece movement in the vertical direction while the lateral gap handles horizontal positioning, thereby improving overall fastening reliability.
Solution Approach 2:
By introducing vertical clamping capability through the second clamping gap, the invention adds dimensional stability to the traditional lateral clamping system. This multi-dimensional clamping approach prevents workpiece settlement and movement, significantly improving fastening reliability without compromising the simplicity of the individual clamping mechanisms.
3Ease of operation
If a single clamping gap is used, then the device is easy to operate, but the ergonomic performance is poor
Solution Approach 1:
The vice operates as two independent single-gap vices combined into one unit. Each clamping gap can be operated separately with its own screw mechanism, allowing the user to select the most ergonomic fastening direction for each specific workpiece. This segmentation maintains the simplicity and ease of operation of traditional single-gap vices while providing enhanced ergonomic flexibility.
Solution Approach 2:
The addition of vertical clamping capability provides another operational dimension, allowing users to choose between horizontal and vertical fastening approaches based on workpiece geometry and personal ergonomics. This multi-directional capability improves working comfort without significantly increasing operational complexity, as each gap operates independently with familiar screw mechanisms.
4Ease of operation
If the anvil surface is located behind the jaw in a blind area, then the vice structure is compact, but the accessibility is poor
Solution Approach 1:
The anvil surface is repositioned from a blind area behind the jaw to an accessible location on the front face of the vice body, utilizing the vertical space created by the second clamping gap. This repositioning allows the anvil to be easily accessible for pounding operations without requiring the user to reach into blind areas or compromise the compact structure of the vice.
