Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fastening member holders are provided in the lower case to hold fastening members for fixing upper circuit components, then the upper circuit components can be securely fixed, but the space for arranging lower circuit components in the lower case is limited
Solution Approach 1:
The fastening member holders are relocated from the lower case to the upper case, utilizing the vertical dimension and the space above the lower case. This allows the lower case to be fully utilized for arranging lower circuit components while the upper case provides the fastening function, effectively using three-dimensional space to resolve the spatial conflict.
Solution Approach 2:
The circuit assembly is divided into functional zones: the upper case is dedicated to holding fastening members and upper circuit components, while the lower case is dedicated to accommodating lower circuit components. This segmentation allows each case to be optimized for its specific function without spatial interference.
2Device complexity
If fastening member holders are integrated into the lower case structure, then the assembly structure is simplified, but the design flexibility for arranging lower circuit components is reduced
Solution Approach 1:
By moving the fastening member holders to the upper case, the invention utilizes the vertical dimension to separate the fastening function from the lower case plane. This maintains structural simplicity while fully preserving the layout flexibility of the lower case for various circuit component arrangements.
3Volume of stationary object
If the circuit assembly size is reduced to improve compactness, then spatial efficiency is improved, but the space for accommodating both upper and lower circuit components becomes constrained
Solution Approach 1:
The invention transitions from a two-dimensional planar arrangement to a three-dimensional configuration by placing fastening member holders in the upper case. This vertical utilization of space allows the lower case to be fully packed with lower circuit components without interfering with the fastening function, thereby reducing overall assembly volume while maintaining component accommodation capacity.
Solution Approach 2:
The upper circuit components and their fastening members are effectively nested within or above the lower case structure, utilizing the vertical space above the lower circuit components. This nested arrangement maximizes the use of available volume without increasing the horizontal footprint of the assembly.
