Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If exercise equipment is replaced with new equipment having built-in motion sensing functions, then motion sensing interactive applications are provided, but cost increases and recycling issues arise
Solution Approach 1:
The motion sensing function is segmented from the exercise equipment itself and implemented as a separate add-on module. The pressure sensing film is installed on specific components of existing equipment, allowing motion sensing capabilities to be added without replacing the entire equipment system.
Solution Approach 2:
The pressure sensing film can be applied to multiple different exercise equipment components (handlebars, pedals, seats, etc.) to provide various motion sensing functions. This universal application approach allows a single sensing technology to enhance multiple types of equipment without requiring specialized replacement equipment for each function.
2Adaptability or versatility
If exercise equipment is replaced with new equipment having built-in motion sensing functions, then motion sensing interactive applications are provided, but recycling issues arise
Solution Approach 1:
By segmenting the sensing function into a separate installable module rather than integrating it into the core equipment structure, the original equipment can remain intact and be reused or recycled while the sensing module can be removed, updated, or repurposed independently.
Solution Approach 2:
The pressure sensing film is designed as a removable add-on that can be recovered and reused across different exercise equipment units. This approach allows the sensing components to be recovered and redeployed rather than discarded with each equipment replacement, reducing waste and recycling issues.
3Measurement precision
If pressure sensing elements are tightly disposed on exercise equipment components, then real-time motion sensing is achieved, but device complexity increases
Solution Approach 1:
The patent uses a flexible pressure sensing film that can be tightly disposed on curved and irregular surfaces of exercise equipment components such as handlebars, pedals, and seats. This thin film structure achieves real-time pressure sensing without adding significant structural complexity, as it conforms to existing component shapes rather than requiring rigid sensor housings.
Solution Approach 2:
The flexible film acts as an intermediary layer between the user's body and the exercise equipment component. It mediates the pressure transmission while maintaining the original component structure, thereby achieving accurate pressure sensing without modifying or complicating the underlying equipment structure.
