One-Piece Remote Control Housing for Easier Assembly and Service
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control devices are complex to manufacture and assemble, requiring skilled personnel and specialized tools, which increases assembly time and cost, and makes servicing difficult.
Innovation Solution
A remote control device with a single-piece casing that houses a chassis, end insert, keypad, and display, where the chassis and end insert are secured to the casing using threaded screws, simplifying assembly and service.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple pieces of housing are used to construct the remote control, then the structural integrity and protection of internal components is improved, but the assembly complexity and manufacturing difficulty increases
Solution Approach 1:
The patent merges multiple housing pieces into a single integrated housing structure that encloses all internal components (chassis, circuit board, battery, keypad). This single housing piece provides complete structural protection while eliminating the need to assemble multiple housing segments, thereby reducing assembly complexity while maintaining structural integrity.
2Strength
If multiple pieces of housing are used with snapping or gluing methods, then the structural integrity is improved, but the ease of disassembly for repair or service deteriorates
Solution Approach 1:
The patent segments the remote control into a permanent housing structure and removable internal modules (chassis, circuit board, battery). The housing itself remains as a single intact piece for structural strength, while internal components are designed to be independently removable through the housing openings, enabling easy service access without damaging the housing structure.
3Adaptability or versatility
If various components are fastened together and placed in housing pieces, then the device functionality is improved, but the assembly time and cost increases
Solution Approach 1:
The patent designs the housing with pre-formed openings and integrated mounting structures that allow components to be directly inserted and secured in their final positions. The housing includes built-in features such as recesses, clips, and alignment guides that enable components to be quickly positioned and fixed without requiring separate fastening operations or specialized tools, thereby reducing assembly time while maintaining full device functionality.

AI summary
A remote control device is disclosed. A single-piece casing has a front surface, rear surface, and pair of opposing side surfaces disposed between the front and rear surfaces. An inner cavity is formed within the casing between the top, bottom and side surfaces and extends along at least part of a length of the casing. A front opening is formed in the front surface and extends into the inner cavity. The front opening is configured to receive a display. At least one key opening is formed in the front surface and extends into the inner cavity. A keypad is configured to be disposed within the inner cavity and includes at least one key positioned on the keypad to extend through the at least one key opening. A chassis has a body configured to be disposed within the inner cavity at least beneath the keypad and the front opening.
