Machine Tool Energy Supply Device Nesting and Weight Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large machine tools, such as chisel hammers, face difficulties in handling due to uneven weight distribution, leading to instability and potential damage, especially to the energy supply components which are often exposed.
Innovation Solution
The machine tool design incorporates an energy supply device that can be positioned between two housing areas, with interfaces for both mechanical and electrical connections, ensuring stable integration and balanced weight distribution, and optionally includes a ventilation channel with a fan for cooling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the energy supply device is positioned in exposed parts of the machine tool for easy access, then the ease of operation is improved, but the reliability deteriorates due to increased risk of damage from drops or impacts
Solution Approach 1:
The energy supply device is nested within the machine tool housing, specifically positioned in the counterweight element that is integrated into the housing structure. This nesting approach protects the energy supply device from external damage while maintaining accessibility through the housing design, resolving the contradiction between protection and ease of access.
Solution Approach 2:
The machine tool housing is segmented into functional regions, with the energy supply device housed in a dedicated compartment within the counterweight element. This segmentation allows the energy supply device to be protected within its own enclosed space while the housing structure provides overall protection, balancing reliability with operational accessibility.
2Stability of the object's composition
If the machine tool has a balanced mass distribution for stability, then the stability is improved, but the ease of operation deteriorates due to increased weight and difficulty in handling
Solution Approach 1:
The counterweight element serves a dual function: it provides the necessary mass for stable operation of the percussion mechanism while simultaneously housing the energy supply device. By integrating the battery into the counterweight, the design achieves balanced mass distribution for stability without adding separate heavy components, thus maintaining ease of operation.
Solution Approach 2:
The counterweight element and energy supply device housing are merged into a single integrated structure. This combination eliminates the need for separate counterweight and battery compartments, achieving stable mass distribution while reducing overall complexity and maintaining manageable weight for hand-held operation.
3Device complexity
If the energy supply device is integrated into the machine tool housing for compact design, then the device complexity is reduced, but the ease of repair deteriorates due to difficulty in accessing and replacing the energy supply device
Solution Approach 1:
The energy supply device is designed with dynamic accessibility - while integrated into the housing for compactness, it can be quickly accessed by opening the housing or removing the counterweight element. This dynamic design allows the system to transition between integrated (for compactness) and accessible (for repair) states, resolving the contradiction between integration and ease of maintenance.
