Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In serially connected light-emitting systems, if one light-emitting unit is damaged, it disrupts data transmission, causing subsequent units to malfunction and preventing them from operating.
Innovation Solution
The system incorporates a shunt node and auxiliary input terminals in each light-emitting unit, allowing data to be transmitted through auxiliary paths when a main path is disrupted, ensuring that subsequent units can still receive data and operate even if one unit is damaged, without the need for additional output terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If light-emitting units are connected in a single-line series structure, then the device complexity is reduced and ease of operation is improved, but the reliability deteriorates because one damaged unit causes all subsequent units to malfunction
Solution Approach 1:
The patent divides the single data transmission path into multiple segments by introducing auxiliary input terminals and alternative data transmission paths. Each light-emitting unit has both a main input terminal (receiving data from the previous unit) and an auxiliary input terminal (receiving data directly from the controller or previous units), creating segmented redundant paths that prevent single-point failure from disabling the entire system.
Solution Approach 2:
The patent changes the data transmission parameter from a single sequential path to multiple parallel paths by enabling light-emitting units to receive data through either their main input terminal or auxiliary input terminal. This parameter change allows the system to dynamically switch between different data transmission routes, maintaining reliability while preserving the simple series connection structure.
2Reliability
If auxiliary input terminals and shunt nodes are added to create alternative data paths, then the reliability is improved, but the device complexity increases
Solution Approach 1:
The auxiliary input terminals serve multiple functions: they can receive data directly from the controller's data output terminal, receive data from previous light-emitting units through shunt nodes, and provide alternative paths when main paths fail. This multi-functionality allows the system to achieve redundancy without adding completely separate independent systems, thereby limiting the increase in device complexity.
Solution Approach 2:
The patent implements a nested structure where auxiliary data transmission paths are embedded within the existing series connection framework. The shunt nodes tap into existing data lines and route them to auxiliary terminals, creating nested alternative paths that utilize the existing circuit topology rather than requiring completely separate parallel systems.
3Reliability
If data is transmitted through multiple paths, then the reliability is improved, but the loss of information may increase due to potential data synchronization issues
Solution Approach 1:
The controller performs preliminary actions by sending the same data packets through both the main data transmission path and auxiliary data transmission paths simultaneously or in predetermined sequences. This preliminary duplication ensures that data arrives at light-emitting units through multiple paths with known timing relationships, preventing information loss or desynchronization.
Solution Approach 2:
The system implements feedback mechanisms where light-emitting units monitor the data received through both main and auxiliary paths, detect any discrepancies or failures, and switch to the appropriate path. This feedback ensures data integrity by comparing received data from multiple paths and correcting or selecting the valid data stream.
