Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate holders are used to hold multiple tool bits, then each tool bit can be securely held, but the device complexity and number of parts increases
Solution Approach 1:
The patent combines multiple tool bit holding functions into a single resiliently deformable bit holder that can simultaneously hold multiple interchangeable tool bits. The bit holder acts as an integrated component with multiple holding positions, eliminating the need for separate holders for each tool bit while maintaining secure holding capability through its deformable structure that adapts to each bit
2Ease of manufacture
If traditional rigid holders are used, then manufacturing is simple, but space utilization within the device is inefficient
Solution Approach 1:
The patent employs a resiliently deformable bit holder that can dynamically change its shape and configuration. The holder can deform to accommodate different tool bit sizes and shapes, allowing efficient use of the available space within the device. This dynamic capability enables compact arrangement of multiple tool bits without requiring excessive clearance, while the material and basic structure remain simple to manufacture
Solution Approach 2:
The resiliently deformable bit holder changes its physical parameters (shape, volume, configuration) based on the inserted tool bits. This parameter change allows the holder to optimize space utilization by adapting its form to fit the specific combination of tool bits present, achieving efficient space use without complex manufacturing
3Volume of moving object
If a compact design with multiple bit holding spaces is implemented, then space efficiency improves, but the reliability of securing each individual tool bit may be compromised
Solution Approach 1:
The resiliently deformable bit holder provides different local qualities at different positions and regions. Each portion of the holder can independently deform to provide optimal securing force for the specific tool bit at that location. This localized adaptation ensures reliable securing of each individual tool bit even when multiple bits are held in a compact arrangement, as each bit receives customized holding pressure from the deformable structure
