Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If functional workaround method is used to modify operation of manufactured semiconductor chip, then performance discrepancy can be addressed, but fundamental problem of the semiconductor chip cannot be solved
Solution Approach 1:
The patent implements dynamic reconfigurability by allowing the processing order of control sequences to be changed after manufacturing. The processor can receive requests from external devices and dynamically reorder control sequences, enabling the semiconductor device to adapt its function post-manufacturing while maintaining reliable operation through structured control flow management
2Adaptability or versatility
If hardware changes are made after manufacturing, then functional adaptability is improved, but manufacturing cost increases
Solution Approach 1:
The patent replaces physical hardware modification with software-based control sequence reordering. Instead of physically changing hardware circuits after manufacturing (which would increase cost and complexity), the system uses programmable control sequences that can be dynamically reordered through software requests, achieving functional adaptability without additional manufacturing costs
Solution Approach 2:
The patent changes the parameter of control sequence processing order rather than modifying hardware structure. By allowing the processing order parameter of control sequences to be dynamically adjusted based on external requests, the system achieves functional flexibility while maintaining the same physical hardware, thus avoiding increased manufacturing costs
3Stability of the object's composition
If control program sequences are executed in fixed order, then hardware operation is stable, but functional flexibility is reduced
Solution Approach 1:
The patent introduces dynamic reconfigurability to the control sequence execution, allowing the processing order to change from fixed to variable. The system maintains stability through structured control sequences while enabling functional flexibility by allowing external devices to request and implement reordering of these sequences, thus resolving the contradiction between stability and adaptability
