Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal body stacks on top of the pin and moves longitudinally down the pin to secure coupling, then the terminal body can be securely attached to the pin, but additional space above the pin is required which is not optimal for various applications
Solution Approach 1:
The patent transitions from longitudinal coupling (stacking on top) to transverse coupling (coupling through the side). The terminal body is designed with a transverse opening that receives the pin horizontally, eliminating the need for vertical stacking space. This dimensional change allows secure attachment while minimizing the space requirement above the pin.
Solution Approach 2:
Instead of the terminal body moving down onto the pin (vertical approach), the pin is inserted through the terminal body from the side (horizontal approach). This inversion of the coupling direction eliminates the need for clearance space above the pin while maintaining secure attachment through the locking member mechanism.
2Extent of automation
If a locking member with biasing wings is used to automatically secure the terminal body to the pin, then automatic securing is achieved, but the terminal body must stack on top of the pin requiring additional space
Solution Approach 1:
The locking member mechanism is reoriented from vertical operation to horizontal operation. The transverse opening allows the pin to enter horizontally, and the locking member engages the pin through lateral movement rather than vertical stacking, maintaining automatic securing while eliminating space requirements above the pin.
Solution Approach 2:
The locking member acts as an intermediary that enables automatic securing through a different mechanism. Instead of relying on vertical stacking and longitudinal movement, the locking member engages the pin through the transverse opening, providing automatic attachment without requiring clearance space above the pin.

AI summary
The subject invention provides for a motion transmitting remote control assembly (38) for transmitting motion in a curved path, including a terminal body (62) defining a longitudinal axis (A) and a cavity (66). The terminal body (62) further defines a first opening (70) extending transverse to the longitudinal axis (A). A locking member (114) is disposed within the cavity (66) and is movable between a locked position and an unlocked position. The locking member (114) has a trigger portion (126) retaining the locking member (114) in the unlocked position and a securing portion (128). A biasing member (116) is disposed within the cavity (66) and abuts the locking member (114). The terminal body (62) further defines a second opening (72) extending transverse to both the longitudinal axis (A) and the first opening (70) into the cavity (66). The second opening (72) provides access to the trigger portion (126) to release the locking member (114) from the unlocked position to the locked position and the securing portion (128) at least partially closes the second opening (72).
