Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool designs require a larger tool rest to absorb slack in linear members, leading to a less compact setup.
Innovation Solution
A compact tool rest design that incorporates a base, a rotatably supported tool holder, a rotational mechanism, flexible linear members connected to a winding device, and fluid pipes for controlling tool mounting and removal, which prevents slack by winding up the linear members as the tool holder rotates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a concentrated slack absorbing portion is used to absorb the slack of the linear member, then the linear member slack is absorbed, but the size of the tool rest increases
Solution Approach 1:
The patent applies the dynamics principle by making the linear member itself dynamic through rotation around its longitudinal axis. As the tool holder rotates, the linear member winds around the winding core, dynamically absorbing slack without requiring a large static slack absorbing portion. This transforms the slack absorption function from a static structural requirement to a dynamic operational process.
Solution Approach 2:
The patent utilizes the flexible shells principle by employing a flexible linear member that can bend and wind around the winding core. The linear member's flexibility allows it to coil around the core during tool holder rotation, effectively absorbing slack while maintaining a compact tool rest structure. This replaces the need for rigid, space-consuming slack absorption mechanisms.
2Adaptability or versatility
If the tool holder rotates, then tool mounting and removal is enabled, but slack is generated in the linear member
Solution Approach 1:
The patent applies preliminary action by pre-arranging the linear member to wind around the winding core before rotation begins. The winding core is positioned and configured in advance to receive and guide the linear member during rotation. This preliminary setup ensures that as the tool holder rotates, the linear member smoothly winds around the core without generating excessive slack or requiring post-rotation adjustments.
Solution Approach 2:
The winding core serves as an intermediary element between the rotating tool holder and the linear member. It mediates the interaction by providing a surface for the linear member to wind around during rotation. This intermediary structure allows the linear member to accommodate the rotational motion while maintaining tension and preventing slack, enabling tool mounting and removal without shape distortion.
3Ease of operation
If multiple linear members are used for fluid control, then tool mounting and removal control is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by designing a single winding device and winding core that serves multiple linear members simultaneously. Instead of providing separate winding mechanisms for each fluid control linear member, the invention uses one multi-functional winding core around which multiple linear members can wind during tool holder rotation. This reduces device complexity while maintaining ease of operation for controlling multiple fluid lines.
Solution Approach 2:
The patent merges multiple linear members into a unified winding system. Multiple fluid control linear members are combined and wound around the same winding core during tool holder rotation. This consolidation reduces the number of separate winding devices needed, simplifying the overall device structure while preserving the ability to control multiple fluid lines for tool mounting and removal operations.
