Hook and Recess Engaging Structure for Electronic Device Casings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods for assembling electronic devices result in components that are difficult or impossible to disassemble, leading to increased production costs and labor due to the need for extra devices or materials.
Innovation Solution
The use of specific hooks and recesses in the engaging structure allows for easy assembly and disassembly by creating a gap between the hook and recess, enabling the hook to be pulled out and the components to be detached without additional equipment or materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional assembly methods (rubber, hooks, supersonic wave) are used, then assembly is achieved, but disassembly becomes impossible or requires additional equipment
Solution Approach 1:
The engaging structure is divided into distinct segments: the hook portion and the recess portion with ribs. This segmentation allows each component to perform its specific function independently - the hook provides engagement while the ribs provide support and enable disassembly through pivot action, resolving the contradiction between secure assembly and easy disassembly
Solution Approach 2:
The engaging structure transitions from a static, permanent connection to a dynamic, reversible connection. The gap between the hook end and recess front edge, combined with the rib structure, enables the connection to dynamically switch between engaged and disengaged states, allowing easy disassembly without compromising assembly strength
2Strength
If permanent engagement methods are used, then assembly strength is improved, but disassembly requires additional equipment or materials
Solution Approach 1:
The engaging structure is designed to be self-sufficient for both assembly and disassembly operations. The rib structure acts as an integrated pivot mechanism that enables disassembly using only the structure's own components, without requiring external tools or additional materials, thus resolving the contradiction between strong engagement and easy disassembly
3Ease of manufacture
If extra assembly equipment or materials are used, then assembly is achieved, but production cost and labor increase
Solution Approach 1:
The invention extracts and eliminates the need for external assembly equipment and materials by integrating all necessary functions into the engaging structure itself. The hook and recess design with rib pivots provides both assembly and disassembly capabilities within the structure, removing dependencies on external tools and thereby improving production efficiency
Solution Approach 2:
The engaging structure performs multiple functions: it provides secure engagement during assembly, maintains structural strength during operation, and enables easy disassembly through the rib pivot mechanism. This multi-functionality eliminates the need for separate assembly and disassembly systems, reducing production costs and improving efficiency

AI summary
The invention discloses an electronic device and an engaging structure thereof. The electronic device comprises a first casing and a second casing. The first casing comprises a plate portion and a plurality of hooks. Each hook is located on the plate portion. The second casing comprises a first side portion, a second side portion, an engaging portion, a first rib and a second rib. The engaging portion is between the first and the second side portions and comprises a plurality of recesses. Each recess is engaged with one of the hooks and has a front edge. A gap is between one end of the hook and the front edge of the recess. The first and second ribs are respectively located on the first and the second side portions. The plate portion is disposed on the first and second ribs. The hook can be detached from the recess by the gap.
