Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the support frame is designed with adjustable angle functionality, then the adaptability for different testing positions is improved, but the device complexity increases due to additional components like adjustment shaft and fixing block
Solution Approach 1:
The support frame employs a dynamic adjustment mechanism where the tray can be rotated to different angles and locked at desired positions. The adjustment shaft with U-shaped grooves and fixing blocks enables the tray to assume multiple angular positions, transforming a static structure into a dynamically adjustable one that adapts to various testing requirements.
Solution Approach 2:
The adjustment mechanism is segmented into discrete functional components: the adjustment shaft with U-shaped grooves, the fixing blocks for locking, and the elastic member for positioning. This segmentation allows each component to perform its specific function independently while contributing to the overall adjustability of the support frame.
2Manufacturing precision
If the support frame includes adjustment mechanism with multiple components, then the positioning accuracy is improved, but the ease of operation deteriorates due to complex assembly and adjustment steps
Solution Approach 1:
The elastic member (spring) automatically positions the fixing block into the U-shaped groove when the tray is released after adjustment. This self-service mechanism eliminates the need for manual positioning or complex locking procedures, allowing operators to simply pull the tray to the desired angle and release it, with the elastic member handling the precise engagement automatically.
Solution Approach 2:
The elastic member acts as an intermediary between the fixing block and the U-shaped groove, providing the force necessary to engage them precisely. This intermediary component simplifies the interaction by automatically ensuring proper alignment and engagement, reducing the operational complexity for the user.
3Volume of moving object
If the tray is designed to retract to a flat position, then the space occupation is reduced, but the stability of the tray during adjustment may be compromised
Solution Approach 1:
The U-shaped grooves are pre-positioned at specific locations along the adjustment shaft, including positions for both the extended (device placement) and retracted (flat) states. This preliminary arrangement ensures that stable positioning is available at both extremes of the tray's range of motion, maintaining stability regardless of whether the tray is extended or retracted.
4Reliability
If elastic member is added to provide positioning force, then the positioning reliability is improved, but the device complexity increases due to additional components
Solution Approach 1:
The elastic member transforms the positioning system from a passive mechanical engagement to an active spring-loaded system. By changing the parameter of applying continuous elastic force, the system achieves more reliable positioning where the fixing block is consistently pushed into the U-shaped groove, ensuring positive engagement and preventing accidental disengagement during use.

AI summary
A support frame includes a column, a rocker arm, a tray, an adjustment shaft and a fixing block. The column is vertically arranged, the rocker arm is horizontally arranged, and the column and the rocker arm are connected by a hinge. The rocker arm includes a transverse support tube connected to the hinge, and the adjustment shaft is arranged inside the transverse support tube. An elastic member has one end connected to the adjustment shaft and another end connected to the column or the hinge. The transverse support tube is provided with multiple U-shaped grooves, and the fixing block is arranged outside the transverse support tube, and the tray is connected to the fixing block. The fixing block passes through the U-shaped groove to be connected to the adjustment shaft; or, a screw passes through the U-shaped groove, to connect the fixing block to the adjustment shaft.
