Hollow-Core Post Fixing Structure for Rugged Casing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing fixing structures for rugged notebook computer casings, which use high-density glass fiber materials and thermal copper pillars, suffer from low bonding strength, making it difficult to efficiently fix the motherboard to the casing.
Innovation Solution
A fixing structure comprising a hollow-core post and a fixing post with a screwing element, where the fixing segment is inserted into the hollow-core post and the screwing element is screwed into an inner screw hole, enhancing the structural strength by forming the hollow-core post and casing integrally from high-density glass fiber material, with ribs for reinforcement and customizable dimensions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If high-density glass fiber material is used for the casing, then cost is reduced and structural strength is improved, but bonding strength with thermal copper pillar is insufficient
Solution Approach 1:
The patent uses high-density glass fiber material as a composite material for the casing, combining glass fibers with a binder to create a material that provides both cost-effectiveness and structural strength while enabling improved bonding characteristics for the fixing mechanism
Solution Approach 2:
The fixing post is divided into distinct segments including an external screwing portion for securing the motherboard and an internal screw hole for engagement with the hollow-core post, allowing each segment to perform its specific function optimally and improving overall bonding reliability
2Reliability
If thermal copper pillar is used to fasten motherboard to casing, then electrical connection is achieved, but bonding strength is low and fixing is inefficient
Solution Approach 1:
The patent merges the functions of mechanical fixing and electrical connection by integrating the screwing element into the hollow-core post structure, creating a unified fixing mechanism that provides both structural bonding strength and electrical connectivity through the conductive glass fiber material
Solution Approach 2:
The hollow-core post acts as an intermediary element between the fixing post and the casing, providing a bonded connection through the glass fiber material that transfers both mechanical loads and electrical signals, thereby improving bonding strength while maintaining electrical connection functionality

AI summary
A fixing structure for a casing and a method for manufacturing the same are provided. The fixing structure for a casing includes a hollow-core post, a fixing post, and a screwing element. The hollow-core post extends from the casing. The fixing post comprises a fixing segment. The fixing segment is inserted into the hollow-core post and has an inner screw hole. The screwing element is inserted into the casing and screwed to the inner screw hole. Therefore, the fixing structure is conducive to enhancement of the strength of engagement between the hollow-core post and the fixing post.
