Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat plate structure is used for the support, then the manufacturing process is simple, but the support strength is insufficient
Solution Approach 1:
The support is divided into a plate body and multiple protrusions that extend from the plate body. The protrusions are positioned to engage with corresponding recesses in the module body, creating a segmented structure that enhances support strength while maintaining manufacturing simplicity through standard stamping or cutting processes.
Solution Approach 2:
The support structure combines a flat plate base material with added protrusion features, creating a composite geometric structure that maintains the simplicity of the base material while adding mechanical interlocking capability. This allows the support to achieve both ease of manufacture and sufficient strength through structural composition rather than material changes.
2Ease of operation
If the support and module body are separated, then assembly is flexible, but assembly deviation occurs affecting bonding quality
Solution Approach 1:
The protrusions on the support are designed to fit into corresponding recesses in the module body, creating a nested fitting relationship. This nesting structure guides the support into precise alignment with the module body during assembly, eliminating assembly deviation while maintaining the flexibility of separate component assembly.
Solution Approach 2:
The protrusions and recesses act as intermediary alignment features between the support and module body. These intermediary structures facilitate precise positioning and registration of the components during assembly, ensuring bonding quality while allowing flexible assembly operations.
3Reliability
If the support surface is large, then bonding area increases, but the support becomes bulky and aesthetic appearance deteriorates
Solution Approach 1:
Instead of increasing the surface area of the plate body, the bonding reliability is enhanced by adding protrusions that extend in the vertical dimension. These protrusions provide additional bonding surfaces and mechanical interlocking features without increasing the horizontal footprint, maintaining a sleek aesthetic appearance while improving bonding reliability.
Solution Approach 2:
The support structure concentrates bonding functionality in specific localized regions through the protrusions rather than requiring a uniformly large surface area. This local quality approach provides sufficient bonding reliability at discrete points while keeping the overall support structure compact and aesthetically pleasing.

AI summary
Embodiments of this application disclose a bracket, a module assembly, and an electronic device, where the bracket may mount a module more stably, to improve position stability of the module in the electronic device. Two first limiting parts arranged opposite to each other are arranged at two ends of the bracket, a second limiting part is arranged on at least one side of the bracket, and the two first limiting parts and the second limiting part are enclosed to form a mounting position for mounting the module. Two first limiting parts at two ends and a second limiting part at least at one side are enclosed to form a mounting position, and both the first limiting parts and the second limiting part may limit the module, so as to limit in all directions and ensure position stability of the module in the bracket. The bracket is further fixed to the electronic device through fixing parts, so that the position stability of the module in the electronic device may be ensured.
