Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If a two-layer folding or sliding design is adopted, then the device achieves a compact form factor with small volume, but the area utilization rate of the lower body is reduced due to partial stacking
Solution Approach 1:
The patent employs a moving mechanism that enables the second body to dynamically transition between stacked and spread positions. This dynamic configuration allows the device to adapt its structure based on usage requirements, resolving the contradiction between compact storage volume and effective usage area by making the stacking relationship changeable rather than fixed.
Solution Approach 2:
The invention introduces a new spatial dimension for movement by allowing the second body to move not only vertically for stacking but also horizontally to achieve complete spreading. This dimensional expansion enables the device to fully utilize the lower body's area when spread, while maintaining compact volume when stacked, thus resolving the area utilization contradiction.
2Shape
If the second body is stacked on the first body, then the device achieves a compact form factor, but the area utilization rate of the first body is reduced
Solution Approach 1:
The moving mechanism enables the device to dynamically switch between compact stacked shape and expanded spread shape. This dynamic capability allows the device to maintain compact form factor when needed while fully utilizing the first body's area when spread, resolving the contradiction between shape compactness and area utilization.
Solution Approach 2:
The invention changes the structural parameters of the device by introducing a moving mechanism that alters the relative position and orientation of the two bodies. This parameter change enables the transition from a compact stacked configuration to a fully spread configuration, maximizing area utilization while maintaining the ability to return to compact form.
