Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pawl device with spring is used to hold mobile devices, then the device can securely hold phones and planar devices, but the structure becomes complicated and manufacturing cost increases
Solution Approach 1:
The patent removes the spring component from the pawl device, extracting the problematic element that caused complexity and reliability issues. The redesigned device uses a simple pawl mechanism without spring, achieving both structural simplification and maintained holding capability through geometric constraint design.
Solution Approach 2:
The holding device is segmented into distinct functional components: the pawl element for engagement, the slot for movement, and the guide structure. This segmentation allows each component to perform its specific function efficiently without requiring complex spring-based mechanisms, reducing overall device complexity while maintaining reliability.
2Adaptability or versatility
If a spring-based pawl device is used, then the device can adapt to different sizes, but the spring reaches fatigue point and fails over time
Solution Approach 1:
The spring is completely removed from the design, eliminating the component subject to fatigue. The adaptability function is achieved through the pawl's ability to engage at different positions along the slot, providing size adaptability without relying on elastic deformation of a spring.
Solution Approach 2:
The device incorporates dynamic elements through the movable pawl that can slide along the slot and engage at different positions. This dynamic adjustment capability provides adaptability to different device sizes while maintaining reliability through purely mechanical engagement without fatigue-prone spring components.
3Reliability
If a complicated pawl device structure is used, then the holding function is achieved, but the manufacturing cost becomes high
Solution Approach 1:
By removing the spring and complex adjustment mechanisms, the patent dramatically simplifies the manufacturing process. The holding function is achieved through simple geometric features (pawl, slot, guide) that can be manufactured using basic machining or molding processes, significantly reducing manufacturing cost while maintaining reliable holding capability.
Solution Approach 2:
Instead of using a complex active mechanism (spring-based pawl device) to achieve holding function, the patent inverts the approach by using a simple passive geometric constraint system. The holding function emerges from the geometry of the pawl and slot interaction rather than from an active spring mechanism, making it simpler and cheaper to manufacture.

AI summary
An adjustable stand for mobile devices includes a board-like body, and a first holding unit and a second holding unit. The first holding unit is movable between the upper end and the bottom end of the body. The second holding unit is movable between the left side and the right side of the body. Two lateral members are respectively connected to the left side and the right side of the body. A support includes a bar with two arms extending from two ends of the bar. Each arm has a connector and two connectors are pivotably connected to the left and right sides of the body. The bar can be put on a desk top. The mobile device is positioned by the first and second holding units.
