Symmetrical Clamp Arm Attaching Structure for Reliable Tool Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attaching/detaching structures for workpieces, molds, and tools require operators to perform multiple complex operations, including holding components steady and manipulating knobs, which can lead to instability and increased risk of accidental movement during attachment and detachment.
Innovation Solution
The proposed structure features a base member with a seating surface and an operation chamber containing symmetrical clamp arms that are rotatably supported, allowing for easy engagement and disengagement of connecting members using an engaging member and urging mechanism, minimizing the need for operator force to stabilize the attachment arm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator uses the conventional attaching/detaching structure with a knob and spring mechanism, then the holder can be attached to the attachment, but the operator must hold the taking out arm down with one hand and manipulate the knob with the other hand, requiring multiple simultaneous operations and close attention to prevent position shifting
Solution Approach 1:
The attaching/detaching structure is segmented into two independent operations: positioning (aligning the engagement protrusion with the engagement recess) and securing (rotating the locking lever to engage the locking protrusion). This segmentation allows the operator to first attach the holder without complex simultaneous operations, then separately secure it, improving ease of operation while maintaining reliability
Solution Approach 2:
The structure incorporates a preliminary positioning phase where the engagement protrusion aligns with the engagement recess before the locking mechanism is activated. This preliminary action ensures proper positioning is achieved before securing, eliminating the need for simultaneous holding and manipulating operations and simplifying the overall process
2Reliability
If the operator performs multiple simultaneous operations to attach/detach the holder, then the attachment can be secured, but the complexity of performing a plurality of operations at the same time increases the risk of position shifting
Solution Approach 1:
The attachment process is divided into distinct sequential steps: positioning the holder with the engagement protrusion, then rotating the locking lever to engage the locking protrusion. This segmentation reduces operation complexity from multiple simultaneous actions to simple sequential actions, while the two-protrusion locking mechanism ensures reliable security
Solution Approach 2:
The locking lever acts as an intermediary mechanism that translates a simple rotational motion into the engagement of the locking protrusion with the engagement recess. This intermediary simplifies the operator's task to a single rotational action while ensuring secure attachment through the interlocking protrusions

AI summary
Provided is an attaching/detaching structure that operates reliably with simple operation. The attaching/detaching structure attaches/detaches a second connecting member (4) to/from a first connecting member (3). An operation chamber (8) formed in a base member (5) of the second connecting member (4) is connected to the outside of the base member (5) via an insertion hole (7) opened to a seating surface (6) of the first connecting member (3). Two clamp arms (10) and (11) are provided in the operation chamber (8) so as to be symmetrical around an axial center of the operation chamber (8). An engaging portion (16, 17) is formed at one end (10b, 11b) in longitudinal direction of each of the clamp arms (10, 11). An engaging member (32) protruding from the second connecting member (4) can be inserted into the insertion hole (7). A lock portion (34) in which the engaging portions (16, 17) can be engaged is formed in the engaging member (32).
