Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a locking element with notches and a locking piece mechanism is used, then the seat can be tilted to multiple angles, but the operation becomes complex and requires significant effort
Solution Approach 1:
The patent applies the dynamics principle by making the locking piece movable rather than fixed. The locking piece can dynamically transition between engaged and disengaged states with a single pushing action, allowing the seat to tilt freely when disengaged and lock at desired angles when engaged. This dynamic mechanism replaces complex multi-component locking systems with a simple movable locking piece that responds to user input.
Solution Approach 2:
The patent extracts the essential locking function from a complex mechanism and isolates it into a single locking piece that interacts with notches on the locking element. By removing unnecessary intermediate components and focusing on the core engagement between the locking piece and notches, the system achieves multi-angle tilting with simplified operation requiring minimal effort.
2Reliability
If a complex locking mechanism with multiple components is used, then the seat can be securely locked at various angles, but the device complexity increases
Solution Approach 1:
The patent extracts the locking function into a single essential component - the locking piece - that engages with notches on the locking element. This extraction eliminates redundant components while maintaining secure locking at various angles. The notches provide reliable engagement points, and the locking piece provides the necessary locking action without requiring additional mechanisms.
Solution Approach 2:
The locking element serves multiple functions: it provides the notches for angular positioning, acts as the locking mechanism when engaged, and allows free movement when disengaged. The control rod also serves dual purposes as both a control element and a structural component of the assembly. This multi-functionality reduces the total number of components while maintaining reliability.

AI summary
The assembly contains a base and a tilt adjustment member. The base has a frame with a seat attachment piece for attaching the frame to a seat cushion of a seat. A locking element is configured in the frame and has a number of notches. In front of the locking element, the frame has a fastening section so that the tilt adjustment member can be accommodated. Each of the lateral sides of the frame has a through hole for a control rod to thread through. The tilt adjustment member contains a swing block, a seat, a locking piece, and a twisting element. By configuring the locking element and the tilt adjustment member on the base, and by using the control rod to engage the locking piece of the tilt adjustment member to interact the notches of the locking element, the seat can be tilted with simple operation and limited effort.
