Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If existing jumping robot structures are used, then jumping function is achieved, but structural complexity increases and energy utilization efficiency decreases
Solution Approach 1:
The jumping mechanism is divided into independent functional modules: elastic potential energy storage module (springs), energy release module (latch mechanism), and motion transmission module (connecting rods). This segmentation allows each component to be optimized independently, reducing overall structural complexity while maintaining high energy utilization efficiency through specialized design of each segment.
Solution Approach 2:
The patent combines multiple functions into integrated components: the elastic deformation of the spring body simultaneously provides both energy storage and the jumping force, while the connecting rods integrate motion transmission and structural support functions. This merging reduces the number of separate components, simplifying the overall structure while preserving energy efficiency.
2Adaptability or versatility
If existing jumping robot structures are used, then jumping capability is achieved, but adaptability to complex environments is limited due to single motion form
Solution Approach 1:
The robot integrates multiple motion capabilities into a single platform: the jumping mechanism provides vertical propulsion for obstacle clearance, while the balance wheel assembly enables rotational motion and posture adjustment. This multi-functional design allows the robot to adapt to various terrain conditions (flat surfaces, slopes, obstacles) without requiring completely separate motion systems, thereby enhancing environmental adaptability while controlling overall complexity.
Solution Approach 2:
The balance wheel is designed as a dynamically adjustable component that can rotate to different angles and positions during operation. This dynamic adjustability allows the robot to modify its motion characteristics in real-time based on terrain conditions, enabling transitions between different motion modes (jumping, rolling, balancing) to enhance adaptability to complex environments.
3Duration of action of moving object
If jumping mechanism is added to robot, then obstacle crossing capability is improved, but continuous jumping capability is lost
Solution Approach 1:
The elastic springs are pre-loaded with potential energy before each jumping sequence, and the latch mechanism is pre-positioned to control the timing of energy release. This preliminary preparation allows the robot to execute rapid successive jumps without requiring complex mid-sequence adjustments, as the system is already configured for the next jump action. The reset mechanism simply needs to re-engage the latch, a simple action that enables continuous jumping capability.
4Use of energy by moving object
If springtail movement mechanism is implemented, then energy utilization efficiency is improved, but structural simplicity must be maintained
Solution Approach 1:
The elastic springs serve as self-contained energy storage devices that automatically recharge during the robot's movement or idle periods. The deformation and recovery of the spring body is a self-service process that requires no external power input or complex control systems, yet provides high energy utilization efficiency by directly converting elastic potential energy into jumping motion. This self-service characteristic maintains structural simplicity while achieving excellent energy efficiency.
