Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery is accommodated within the cutting tool, then the cutting tool can be made compact, but the battery capacity is limited and requires frequent replacement
Solution Approach 1:
The cutting tool is divided into two separate components: the cutting tool body (with sensor and power path) and the battery (accommodated in a housing). This segmentation allows the battery to be optimized for capacity independently of the cutting tool size constraints, while the cutting tool remains compact for operation.
Solution Approach 2:
A power path serves as an intermediary connection between the battery in the housing and the sensor in the cutting tool. This power path transmits electrical energy from the battery to the sensor, enabling extended operational time without requiring the battery to be physically integrated into the cutting tool body.
2Volume of moving object
If frequent battery replacements are required, then the cutting tool can remain compact, but productivity is reduced due to interruptions
Solution Approach 1:
By separating the battery from the cutting tool body and accommodating it in an external housing, the system allows for larger battery capacity without increasing cutting tool size. This enables longer operational periods between battery replacements, thereby improving productivity.
Solution Approach 2:
The battery is pre-charged to full capacity in the housing before being connected to the cutting tool. This preliminary charging action ensures maximum operational time is available before the next replacement cycle, minimizing interruptions and improving productivity.
3Loss of information
If real-time evaluation of cutting tool state is required, then continuous data collection is needed, but limited battery capacity prevents this
Solution Approach 1:
The power path acts as an intermediary that enables continuous power supply to the sensor from the high-capacity battery in the housing. This allows the sensor to continuously collect real-time data about the cutting tool state without being constrained by limited battery capacity.
Solution Approach 2:
The battery is pre-charged to full capacity and positioned in the housing before operation begins. This preliminary preparation ensures that sufficient energy is available from the outset to support continuous real-time data collection throughout the entire operational period.

AI summary
A cutting tool has a cutting bite, a power path, and a housing. The cutting bite includes a cutting edge, a shank that holds the cutting edge, and a sensor attached to the shank. The power path has a first terminal connected to the cutting bite and a second terminal opposite to the first terminal, and supplies power to the sensor. The housing accommodates a battery that stores power to be supplied to the power path, and is connected to the second terminal.
