Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional passive shoe inserts are used, then manufacturing is simple and cost-effective, but foot support is inadequate and does not adjust to movement
Solution Approach 1:
The patent applies dynamics by transforming the static, passive insert into a dynamic system that actively adjusts its properties. The shape memory polymer layer changes its mechanical characteristics in response to stimuli from the sensing layer, enabling the insert to adapt its support properties based on real-time foot movement and pressure conditions.
Solution Approach 2:
The patent implements feedback through the sensing layer that continuously monitors foot pressure and movement, transmitting this information to the shape memory polymer layer. This closed-loop feedback system enables the insert to respond automatically to changing foot conditions, adjusting support levels without user intervention.
2Adaptability or versatility
If shape shifting orthotic sole with sensing layer is implemented, then foot support adapts to movement and placement, but device complexity increases
Solution Approach 1:
The patent utilizes parameter changes by employing a shape memory polymer layer that alters its physical properties (shape, rigidity, or softness) in response to external stimuli. The sensing layer detects changes in foot parameters (pressure, position, movement) and triggers corresponding changes in the polymer's mechanical parameters, enabling dynamic adaptation.
Solution Approach 2:
The patent applies composite materials by combining the shape memory polymer layer with the sensing layer and control system. This composite structure integrates multiple functional materials that work together: the sensing layer detects conditions, the control system processes information, and the shape memory polymer executes the response, creating a unified adaptive system.
3Ease of operation
If constant feedback and automatic adjustment are provided, then foot comfort is enhanced, but energy consumption increases
Solution Approach 1:
The patent applies periodic action by implementing time-based control strategies where the system adjusts support parameters at specific intervals or in response to periodic foot movement patterns. This allows the system to provide necessary adjustments while remaining in a low-power state during periods of minimal activity, reducing overall energy consumption.
Solution Approach 2:
The patent implements self-service through the automatic adjustment mechanism that operates autonomously based on sensing layer input. The system self-regulates support levels without requiring external control or continuous user input, minimizing the need for high-power processing and communication functions, thereby reducing energy consumption.
