Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a hand controller is mounted at a fixed location for controlling the electric lifting table, then the control function is achieved, but the ease of operation deteriorates and the device complexity increases
Solution Approach 1:
The patent extracts the control function from the fixed hand controller and relocates it to the table board surface through touch-sensitive regions. This allows users to operate the lifting table directly at the table surface without needing to reach for a separate controller, significantly improving ease of operation while reducing device complexity by eliminating the need for a dedicated hand controller unit
Solution Approach 2:
The table board is given multiple functions: it serves both as the structural table surface and as the control interface for the lifting mechanism. By integrating control regions directly into the table board, the system achieves multi-functionality where the same component (table board) performs both support and control functions, reducing overall device complexity
2Ease of operation
If a hand controller is provided for controlling the electric lifting table, then the control function is achieved, but the cost increases
Solution Approach 1:
The patent merges the control function with the table board structure by integrating touch-sensitive regions directly into the table surface. This consolidation eliminates the need for a separate hand controller component, reducing material costs, assembly complexity, and overall manufacturing cost while maintaining full control functionality
Solution Approach 2:
The table board serves dual purposes as both the structural surface and the control interface. This multi-functionality reduces the total component count and bill of materials, directly lowering manufacturing costs while ensuring the control function is fully preserved through the integrated touch-sensitive regions
