Recording Device Leg Part with Movable Contact for Surface Irregularity Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recording devices face image quality reduction due to installation surface irregularities, as deformation absorption members between the main body and leg parts cause significant distortion when installed on uneven surfaces.
Innovation Solution
A recording device with a leg part featuring three reference contact parts on the same plane and one movable contact part coupled through an elastic member, which deforms to follow installation surface irregularities, minimizing distortion by distributing weight evenly and stabilizing the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If deformation absorption members are interposed between the main body and each of two support column parts of the leg part, then the influence of installation surface irregularities is reduced, but significant distortion is caused at the joining part between the main body and the leg part when the two deformation absorption members elastically deform in directions different from each other
Solution Approach 1:
The patent divides the support function into three reference contact parts (fixed) and one movable contact part (elastic), segmenting the deformation absorption function to specific locations rather than distributing it uniformly across all support points. This segmentation allows the main body to remain stable while selectively absorbing surface irregularities.
Solution Approach 2:
The patent applies different properties to different contact parts: three contact parts are fixed to provide stable support, while one contact part is made movable with elastic deformation capability to locally absorb surface irregularities. This local differentiation resolves the contradiction by concentrating deformation absorption where it won't cause distortion.
2Adaptability or versatility
If multiple deformation absorption members are used to reduce the influence of installation surface irregularities, then adaptability to uneven surfaces is improved, but the complexity of the device structure increases
Solution Approach 1:
The patent introduces a movable contact part that can dynamically adjust its position through elastic deformation, allowing the device to adapt to various installation surface conditions. This dynamic element provides adaptability without requiring multiple complex deformation absorption members, as the movable part can compensate for irregularities in conjunction with the three fixed reference contact parts.

Function Achieved in This Case
The configuration effectively suppresses twist and distortion of the main body due to installation surface irregularities, maintaining image quality and stability by allowing the movable contact part to adjust to surface irregularities through elastic deformation.
Implementation Method 1
The movable contact part is coupled with the main body through an elastic member that is elastically deformable in a direction that intersects the plane
